GCOR Railroad Operating Rules Exam — Questions and Answers

Question 1: A crew needs to use a hand-operated crossover between two main tracks. What is the correct procedure for lining the switches?

Both switches of the crossover must be opened and properly lined before the movement begins. (Correct answer)
Request the dispatcher to remotely line the crossover switches.
Line only the switch on the track the train is currently occupying.
Line the first switch, move the engine past it, then line the second switch.

Correct answer: Both switches of the crossover must be opened and properly lined before the movement begins.

GCOR Rule 8.12 requires that both switches of a crossover must be opened and lined for the crossover movement before the movement starts. This ensures a continuous and safe route.

Question 2: If an employee receives a radio communication that is incomplete or not understood, what action must be taken?

Wait five seconds and if there is no clarification, proceed as planned.
Ask another crew member for their interpretation of the message.
Act on the portion of the message that was clearly understood.
Treat the communication as if it was not sent and do not act upon it. (Correct answer)

Correct answer: Treat the communication as if it was not sent and do not act upon it.

GCOR Rule 2.6, "Communication Not Understood or Incomplete," states that an employee must not act upon a communication that is not fully understood. They must treat it as if it were not sent. The only exception is if the information suggests a safety hazard, in which case the employee must take the safe course, including stopping movement until clarification is received.

Question 3: A train crew is instructed by a Track Bulletin Form B to protect against men and equipment between MP 10 and MP 12. Upon approaching the limits, what is the first required action?

Stop before entering the limits unless instructed otherwise by the employee in charge. (Correct answer)
Proceed at restricted speed upon entering the limits.
Sound the horn in a specific sequence to warn the work crew.
Contact the train dispatcher to confirm the bulletin is still in effect.

Correct answer: Stop before entering the limits unless instructed otherwise by the employee in charge.

GCOR Rule 15.2, 'Protection by Track Bulletin Form B,' requires that a train must not enter the limits protected by a Form B bulletin until instructed by the employee in charge. A train must stop before the limits unless prior instructions are received.

Question 4: A train crew has been granted 'Track and Time' authority from MP 80 to MP 90 in CTC territory. Within these limits is CP 85, which is a dispatcher-controlled crossover. How does this authority affect their movement at CP 85?

The 'Track and Time' authority does not include interlocking limits, so they cannot enter CP 85.
They may pass the signal only after stopping and waiting 10 minutes.
They may pass the absolute signal at CP 85 displaying a 'Stop' indication without stopping and without communicating with the control operator. (Correct answer)
They must stop before the absolute signal at CP 85 and get separate permission to pass it.

Correct answer: They may pass the absolute signal at CP 85 displaying a 'Stop' indication without stopping and without communicating with the control operator.

GCOR Rule 10.3 (Track and Time) grants authority to occupy the track within specified limits. Unless a control point is specifically designated as a manual interlocking in the timetable, the Track and Time authority includes the limits of the control point. Therefore, a train can pass a controlled signal displaying 'Stop' within their Track and Time limits without stopping or obtaining additional permission.

Question 5: Under GCOR, at what point must the locomotive's bell be rung when approaching a public grade crossing?

Only when the horn signal sequence has been completed
The bell is not required if warning lights and gates are present and functioning
At least 1,500 feet before the crossing and stopped until traffic clears
Not less than one-quarter mile before the crossing until the locomotive clears it (Correct answer)

Correct answer: Not less than one-quarter mile before the crossing until the locomotive clears it

GCOR requires the bell to be rung not less than one-quarter mile before a public crossing and to continue ringing until the locomotive has passed through the crossing.

Question 6: Under GCOR, what must the engineer do when the locomotive alerter (vigilance device) sounds its warning?

Acknowledge the device by pressing the designated button or pedal (Correct answer)
Radio the dispatcher to report the alert condition
Apply the emergency brake immediately
Reduce speed to restricted speed until the alert clears

Correct answer: Acknowledge the device by pressing the designated button or pedal

The engineer must acknowledge the alerter by pressing the designated acknowledgment button or pedal to confirm they are alert and in control.

Question 7: Which of the following actions is explicitly prohibited when a blue signal is displayed on a track, according to GCOR 5.13?

Operating a switch that provides access to the protected track.
Placing other rolling equipment on the same track in a way that blocks the view of the blue signal. (Correct answer)
Using a radio to communicate near the protected track.
Walking on the ballast within 10 feet of the protected track.

Correct answer: Placing other rolling equipment on the same track in a way that blocks the view of the blue signal.

GCOR Rule 5.13 states that a blue signal signifies workmen are on, under, or between rolling equipment. One of the key requirements is that 'Other rolling equipment must not be placed on the same track so as to block or reduce the view of the blue signal.'

Question 8: Which of the following is a key difference between movement authority in an Automatic Block System (ABS) territory versus a Centralized Traffic Control (CTC) territory?

CTC territory does not use intermediate signals, only absolute signals.
In ABS, trains can proceed without any form of track authority.
In CTC, signal indications authorize train movement, while in ABS, signals provide protection but do not authorize movement. (Correct answer)
Reverse movements are not permitted in ABS territory.

Correct answer: In CTC, signal indications authorize train movement, while in ABS, signals provide protection but do not authorize movement.

In CTC territory, block signal indications are the primary method used to authorize train movements. In ABS territory, signals provide information about block occupancy to ensure trains are spaced safely, but the authority to occupy the main track comes from another source, such as a track warrant or timetable authority.

Question 9: Which of the following is required before making a reverse movement on a main track?

The headlight must be set to dim and flashing.
The conductor must walk ahead to protect the movement.
Permission must be obtained from the train dispatcher or control operator, unless within the same signaled block. (Correct answer)
The movement must be made at timetable speed.

Correct answer: Permission must be obtained from the train dispatcher or control operator, unless within the same signaled block.

GCOR Rule 6.4.1, 'Permission for Reverse Movements,' mandates that a train must obtain permission from the train dispatcher or control operator before making a reverse movement on a main track, with the exception of movements staying within the same signaled block in certain territories like CTC.

Question 10: When making a trailing point movement over a spring switch, which of the following is a primary requirement before proceeding?

The train dispatcher must give verbal authorization for the movement.
The switch must be operated by hand to the reverse position and back again.
The movement must not exceed 5 MPH.
A crew member must observe that the switch points are closed and fit properly. (Correct answer)

Correct answer: A crew member must observe that the switch points are closed and fit properly.

For a trailing point movement over a spring switch, the points are forced open by the wheels and then spring back. It is critical to ensure the points are properly closed before the movement starts to prevent a derailment. Testing the switch by hand (lining it over and back) is required only for certain facing point movements under specific signal indications.

Question 11: Under GCOR, when must an engineer reduce speed to 20 mph or less at grade crossings not equipped with automatic warning devices?

Only when flagged by a crew member
Only in inclement weather
Always, regardless of visibility (Correct answer)
Only at night

Correct answer: Always, regardless of visibility

GCOR requires trains to reduce to 20 mph or less at all passive grade crossings (those without automatic warning devices) regardless of conditions.

Question 12: When is the mandatory verbal repetition of a track warrant by the copying employee NOT required according to GCOR?

When the employee has a certified conductor's license.
If the warrant only authorizes movement for less than one mile.
During emergency situations as declared by the railroad.
When the track warrant is transmitted mechanically to a device. (Correct answer)

Correct answer: When the track warrant is transmitted mechanically to a device.

GCOR Rule 14.13 states that repetition is not required when track warrants are transmitted mechanically (e.g., to a computer or fax machine in the cab). In this case, the 'OK' time is given when the warrant is issued, and the standard read-back procedure is bypassed.

Question 13: What is the most important element in performing duties?

Cooperation with fellow employees
Safety (Correct answer)
None of the above
Reporting for duty at the proper place and time

Correct answer: Safety

Explanation: Safety is the most important element in performing duties because it ensures the well-being and protection of oneself and others. By prioritizing safety, individuals can prevent accidents, injuries, and potential harm in the workplace. It also promotes a positive work environment and increases productivity. Safety measures include following protocols, using protective equipment, and being aware of potential hazards. By prioritizing safety, individuals can effectively carry out their duties without compromising their own health and the safety of others.

Question 14: The location of absolute signals controlled by a control operator is a:

Control point (Correct answer)
Control location
Control Operator
Control approach

Correct answer: Control point

Explanation: The location of absolute signals controlled by a control operator is referred to as a control point. This is the designated area where the control operator is stationed to manage and control the absolute signals. It serves as a central point from where the control operator can monitor and regulate the signals to ensure smooth and safe traffic flow.

Question 15: What are signal appliances that are interconnected so that each of their movements follows the other in a proper sequence?

Automatic block signal system
Track warrant signals
Interlocking (Correct answer)
Centralized traffic control

Correct answer: Interlocking

Explanation: Interlocking is the correct answer because it refers to a system of signal appliances that are interconnected in such a way that their movements follow each other in a proper sequence. This system ensures the safe and efficient movement of trains by preventing conflicting movements and maintaining a proper flow of traffic.

Question 16: According to GCOR, what must a crew do upon discovering a broken rail?

Stop and flag any following trains, then await dispatcher instructions
Reduce speed to 10 mph and proceed across the break
Proceed slowly over the broken rail to maintain schedule
Stop immediately, protect both ends of the break, and notify the dispatcher (Correct answer)

Correct answer: Stop immediately, protect both ends of the break, and notify the dispatcher

GCOR requires the crew to stop immediately upon discovering a broken rail, protect both ends of the break, and notify the dispatcher before any other trains approach.

Question 17: When determining a 'sufficient' number of hand brakes to apply on unattended equipment, which of the following set of factors must be considered?

The proximity to the nearest yard and the type of locomotive used.
The time of day and the number of crew members present.
The schedule of the next train to use the track.
The track grade, weather conditions, and tonnage of the cars. (Correct answer)

Correct answer: The track grade, weather conditions, and tonnage of the cars.

GCOR requires a performance-based approach to securing equipment. Employees must evaluate conditions that could cause movement, such as the steepness of the track (grade), wind (weather), and the weight of the cars (tonnage), to determine how many hand brakes are sufficient to hold the equipment safely.

Question 18: Under GCOR, what does it mean when a locomotive is operating 'light'?

The locomotive is operating on tracks with reduced weight restrictions
The locomotive is moving without any cars coupled to it (Correct answer)
The locomotive is operating at less than 50% of its rated horsepower
The locomotive is operating with fewer than the rated number of powered axles

Correct answer: The locomotive is moving without any cars coupled to it

A 'light' locomotive (or 'running light') means the locomotive is moving without any cars or equipment coupled to it.

Question 19: When a locomotive in a consist develops a mechanical failure that causes it to drag or resist movement, what action is required under GCOR?

Reduce speed to 15 mph and proceed to the next siding
Increase throttle on the remaining units to overcome the resistance
Stop the train and take the defective locomotive out of service (Correct answer)
Cut out the traction motors on the defective unit and continue

Correct answer: Stop the train and take the defective locomotive out of service

A locomotive that drags or resists movement creates a dangerous mechanical condition, requiring the train to stop and the defective unit to be removed from service.

Question 20: An employee notices a defective section of track that could potentially affect safe train operations. Under GCOR rules for reporting unusual conditions, what is the employee's IMMEDIATE responsibility?

Only report it if a train is currently approaching the defect.
Fix the defect personally if the tools are available.
Report it by the first available means of communication. (Correct answer)
Wait until the end of the shift to file a written report.

Correct answer: Report it by the first available means of communication.

GCOR Rule 1.1.3 mandates that employees must 'Report by the first means of communication any... defects in tracks, bridges, or signals; or any unusual condition that may affect the safe and efficient operation of the railroad.' This ensures that potential hazards are addressed as quickly as possible.

Question 21: Which of the following is the correct procedure for voiding a track warrant that is no longer needed or must be changed?

The crew simply writes 'VOID' on their copy; no communication with the dispatcher is needed.
The warrant automatically becomes void after a fixed period of two hours.
The crew can verbally agree with the dispatcher to void the warrant.
A new track warrant must be issued that includes the instruction 'Track Warrant No. ___ is void'. (Correct answer)

Correct answer: A new track warrant must be issued that includes the instruction 'Track Warrant No. ___ is void'.

GCOR Rule 14.11 specifies that to change the limits or instructions of a track warrant, a new warrant must be issued. This new warrant must explicitly state, 'Track Warrant NO. ____________ is void,' followed by the number of the warrant being superseded.

Question 22: What action is required when a locomotive's dynamic brakes become inoperative during a descending grade operation?

Tie down hand brakes on the rear cars and continue at slow speed
Increase locomotive throttle to maintain control
Immediately apply emergency brakes and stop the train
Notify the dispatcher and use train brakes to control speed (Correct answer)

Correct answer: Notify the dispatcher and use train brakes to control speed

When dynamic brakes fail on a descending grade, the engineer must notify the dispatcher and rely on the train's air brakes to control speed.

Question 23: A train crew is making a facing point movement over a spring switch that is not protected by a block signal or switch point indicator. What action must be taken?

Report the unprotected switch to the dispatcher after passing it.
Trail the entire train through the switch in the opposite direction first.
The train must stop and a crew member must test the switch by lining it over and back by hand. (Correct answer)
Proceed at restricted speed over the switch.

Correct answer: The train must stop and a crew member must test the switch by lining it over and back by hand.

GCOR Rule 8.9.1 specifies that if a train is making a facing point movement over a spring switch and the switch is not protected by a block signal or switch point indicator, the train must stop and a crew member must test the switch by hand to ensure it is properly lined and the points fit correctly.

Question 24: A single locomotive is being left unattended on a main track. What is the minimum hand brake requirement according to GCOR?

Permission must be received from the dispatcher to leave it without a hand brake.
One wheel must be chocked.
The hand brake on the locomotive must be fully applied. (Correct answer)
The automatic air brake is sufficient if the compressor is running.

Correct answer: The hand brake on the locomotive must be fully applied.

When leaving locomotives unattended, all locomotives in the consist must be secured with a handbrake. This is a specific requirement to ensure the power units themselves are secured against unintended movement.

Question 25: What is a trackside warning detector?

A device that indicates conditions such as overheated journals, dragging equipment, excess dimensions, shifted loads, high water, or slides (Correct answer)
A device that gives warning of track failures
A device to indicate a warning two miles in advance
A device that gives warnings of track conditions.

Correct answer: A device that indicates conditions such as overheated journals, dragging equipment, excess dimensions, shifted loads, high water, or slides

Explanation: A trackside warning detector is a device that indicates conditions such as overheated journals, dragging equipment, excess dimensions, shifted loads, high water, or slides. This device is designed to give warnings about potential hazards or issues on the track, allowing for timely intervention and prevention of accidents or damage to the train or tracks.

Question 26: A train crew is approaching established working limits. Under what condition may their train enter these limits?

Only after receiving direct instructions from the Roadway Worker in Charge (RWIC) controlling the limits. (Correct answer)
After receiving permission from the train dispatcher.
If the governing signal to enter the limits displays a 'Proceed' indication.
If the train is moving at restricted speed.

Correct answer: Only after receiving direct instructions from the Roadway Worker in Charge (RWIC) controlling the limits.

Working limits are under the exclusive control of the Roadway Worker in Charge (RWIC). Regardless of signal indication or dispatcher instructions for movement outside the limits, no train or on-track equipment may enter working limits without the express permission of the RWIC who is responsible for the on-track safety of the work group.

Question 27: According to GCOR, what must occur before a train exceeds 49 mph when operating with a distributed power unit (DPU)?

Communication and control of the DPU must be verified as operational (Correct answer)
The train must reduce to 49 mph permanently
Written authority must be obtained from the dispatcher
The DPU must be disconnected

Correct answer: Communication and control of the DPU must be verified as operational

Before exceeding 49 mph with a DPU, GCOR requires verification that communication and control of the distributed power unit are fully operational.

Question 28: When operating on another railroad, unless otherwise instructed, employees will be governed by:

Safety rules of the railroad they are employed by.
All of the above (Correct answer)
The operating rules and timetable/special instructions of the railroad they are on
Air brake and train handling rules of the railroad they are employed by

Correct answer: All of the above

Explanation: When operating on another railroad, employees will be governed by the safety rules, air brake and train handling rules, and the operating rules and timetable/special instructions of the railroad they are employed. All of these answers are correct because when working on another railroad, employees must follow the rules and regulations of that specific railroad in order to ensure safety and proper train operations.

Question 29: When must the conductor inform the engineer of a restriction?

Anytime it's convenient, but must be done at least 1 mile from the restriction.
After the train passes the last station, but at least 2 miles from the restriction. (Correct answer)
When leaving the initial station
After the train passes two stations in advance of the restriction, but at least after the train passes the last station

Correct answer: After the train passes the last station, but at least 2 miles from the restriction.

Explanation: The conductor must inform the engineer of a restriction after the train passes the last station, but at least 2 miles from the restriction. This ensures that the engineer has enough time to prepare for the restriction and adjust the train's speed accordingly. Informing the engineer earlier than 2 miles from the restriction may not provide enough time for the necessary adjustments to be made.

Question 30: An absolute signal is:

A block or interlocking signal with a number plate.
A block or interlocking signal without a number plate. (Correct answer)
A signal with a number plate.
Any signal displaying a red aspect.

Correct answer: A block or interlocking signal without a number plate.

Explanation: An absolute signal refers to a block or interlocking signal that does not have a number plate. This means that it does not display any specific information or indication, but rather serves as a general signal without any additional instructions. It is important to differentiate absolute signals from other types of signals that may display a red aspect or have a number plate, as they have different meanings and implications for train operations.

Question 31: Under what circumstance is a train permitted to enter CTC territory without a proceed indication on a controlled signal?

If the train is a light engine movement.
When the control operator grants verbal authority to pass a Stop indication or to enter the track between signals. (Correct answer)
During a signal suspension, all trains may enter CTC at restricted speed without authorization.
When entering from a yard track where Yard Limits are in effect.

Correct answer: When the control operator grants verbal authority to pass a Stop indication or to enter the track between signals.

GCOR Rule 10.1 specifies that a train must not enter or occupy any track where CTC is in effect unless a controlled signal displays a proceed indication OR the control operator authorizes the movement. This authorization can be to pass a stop signal or to enter the track between signals.

Question 32: Under GCOR, what must a locomotive engineer do when the train's speed exceeds the authorized maximum?

Contact the dispatcher for a new speed authority
Stop the train immediately
Continue at the exceeded speed until the next station
Reduce speed immediately and report the violation (Correct answer)

Correct answer: Reduce speed immediately and report the violation

When speed exceeds the authorized maximum, GCOR requires the engineer to immediately reduce speed and report the overspeed to the designated supervisor.

Question 33: An employee is instructed by a supervisor to perform an action that they, in good faith, believe violates a safety rule and could cause injury. What is the employee's right and responsibility in this situation?

To report the supervisor to an outside agency immediately.
To refuse the directive and walk off the job.
To obey the supervisor's order without question.
To challenge the directive in good faith. (Correct answer)

Correct answer: To challenge the directive in good faith.

GCOR includes provisions for a 'Good Faith Challenge' (Rule 1.4.1). This allows an employee to challenge a directive they believe would violate a safety rule without fear of reprisal, ensuring that safety is not compromised by a direct order.

Question 34: Under GCOR, when a train is operating in a dark territory, what is the maximum speed permitted when approaching a switch that is not within a signaled territory?

The train must stop 1,500 feet from the switch
The train must reduce to restricted speed while prepared to stop short of the switch (Correct answer)
The train may proceed at normal speed if the switch is lined correctly
The train must obtain verbal authority before passing the switch

Correct answer: The train must reduce to restricted speed while prepared to stop short of the switch

In dark territory, trains must approach switches at restricted speed, prepared to stop short of any obstruction.

Question 35: A train crew receives a track warrant authorizing them to 'WORK BETWEEN' MP 50 and MP 60. Which of the following movements is permitted under this authority?

Proceed directly from MP 50 to MP 60 and report clear.
Move in either direction between MP 50 and MP 60. (Correct answer)
Only move from MP 60 towards MP 50.
Occupy the main track at MP 50 but not proceed towards MP 60.

Correct answer: Move in either direction between MP 50 and MP 60.

GCOR Rule 14.3, 'Operating with Track Warrants,' specifies that a train authorized to 'WORK BETWEEN' two points may move in either direction between those points within the specified limits.

Question 36: Under GCOR, what is the required speed when a train is moving within 500 feet of a standing train or equipment on the same track?

10 mph
Restricted speed (Correct answer)
15 mph
20 mph

Correct answer: Restricted speed

GCOR requires trains to move at restricted speed when within 500 feet of standing equipment on the same track.

Question 37: A train crew is leaving their entire train, with locomotives attached, on a main track siding. In this specific situation, which method of securement is permitted that is normally prohibited for unattended cars?

Applying hand brakes on the locomotives only.
Using only wheel chocks on the lead locomotive.
Depending on the automatic air brake system without applying hand brakes. (Correct answer)
Relying on the dynamic brakes of the locomotive.

Correct answer: Depending on the automatic air brake system without applying hand brakes.

While GCOR 7.6 generally prohibits relying on air brakes, an exception exists when the engine(s) remain attached to the equipment. In this case, the locomotive's air compressors keep the brake system charged, preventing the pressure from bleeding off and making the air brake system a reliable means of securement.

Question 38: What is a crossover?

A combination of two switches that connect two adjacent tracks (Correct answer)
A track connection between two adjacent sidings
A track connection between two or more adjacent dual control switches
A combination of two switches that connect two adjacent trains

Correct answer: A combination of two switches that connect two adjacent tracks

Explanation: A crossover refers to a combination of two switches that connect two adjacent tracks. This allows trains to move from one track to another, typically in opposite directions. By using the crossover, trains can change tracks without having to reverse or make a large detour. This helps to improve efficiency and flexibility in the railway system.

Question 39: Crew members in the engine control compartment must be alert for signals. As soon as a signal becomes visible or audible, crew members must communicate clearly to each other the name or aspect of signals affecting their train.

This only applies to yellow and red signals
This applies only to distant signals
This only applies to yellow and yellow-red flags
This applies to all signals (Correct answer)

Correct answer: This applies to all signals

Explanation: This means that crew members in the engine control compartment must be alert for any signals, regardless of their color or type. As soon as a signal becomes visible or audible, crew members must communicate clearly to each other the name or aspect of the signals affecting their train. This ensures that the crew is aware of any signals and can respond accordingly to maintain safety and control of the train.

Question 40: A train is authorized to enter the main track in CTC territory at a hand-operated switch where no governing signal exists. What must happen before the train occupies the main track?

The crew must provide flag protection in both directions.
The crew must open the switch and wait 5 minutes to establish signal protection.
The control operator must verbally authorize the train to enter the track. (Correct answer)
The train can enter immediately after lining the switch, then report to the dispatcher.

Correct answer: The control operator must verbally authorize the train to enter the track.

According to GCOR Rule 9.17, within CTC territory, before a train enters the track at a hand-operated switch with no governing signal, the control operator must authorize the movement. The control operator is responsible for verifying there are no conflicting movements before granting this authority.

Question 41: When Yard Limits are in effect within CTC territory, which rule takes precedence for authorizing movement on the main track?

Rule 10.1 (Authority to Enter CTC Limits), requiring authorization from the control operator for any main track movement. (Correct answer)
Rule 6.13 (Yard Limits), allowing all movements to proceed at restricted speed without dispatcher contact.
Rule 6.4 (Reverse Movements), which becomes the primary authority for all movements.
The crew can choose which rule to operate under based on the situation.

Correct answer: Rule 10.1 (Authority to Enter CTC Limits), requiring authorization from the control operator for any main track movement.

When Yard Limits are established within CTC territory, the rules are combined. While the principle of moving at restricted speed (from Rule 6.13) still applies unless a signal indicates otherwise, GCOR specifically states that the control operator must still authorize any movement on the main track, per CTC rules. Rule 10.1 authority is required.

Question 42: Which of the following is a mandatory component of an on-track safety job briefing conducted by the RWIC before any work begins?

The expected time of completion for the entire project.
Information on the means by which on-track safety is to be provided for each track to be fouled. (Correct answer)
A review of the previous day's work and any incidents that occurred.
The names and contact information for all train dispatchers on duty in the territory.

Correct answer: Information on the means by which on-track safety is to be provided for each track to be fouled.

Federal regulations (49 CFR § 214.315) and GCOR require that an on-track safety job briefing must, at a minimum, include information on the means by which on-track safety will be provided for each track that workers may foul. This ensures every worker understands the specific type of protection being used (e.g., working limits, lookout, etc.).

Question 43: According to GCOR, when is a crew permitted to exceed the maximum authorized timetable speed?

When making up time for a late train
Never; timetable speed is the absolute maximum unless otherwise authorized (Correct answer)
Only when the track is clear and visibility is good
When authorized by the dispatcher via radio

Correct answer: Never; timetable speed is the absolute maximum unless otherwise authorized

GCOR prohibits exceeding the maximum timetable speed under any circumstances unless a specific written or radio authority has been issued.

Question 44: When a locomotive's automatic brake fails to apply during a required brake test, what action must be taken?

The locomotive may continue if the independent brake is functional
The conductor must authorize continued use and document the defect
The locomotive must be set out and not used until repaired (Correct answer)
The locomotive may move at restricted speed only

Correct answer: The locomotive must be set out and not used until repaired

A locomotive with a failed automatic brake must be set out of service and not used until the defect is repaired.

Question 45: A crew is performing a shoving movement on a main track. According to GCOR 6.5, what is the maximum authorized speed for a freight train during this operation?

10 MPH
20 MPH (Correct answer)
30 MPH
15 MPH

Correct answer: 20 MPH

GCOR Rule 6.5 explicitly states that when cars are shoved on a main track or controlled siding in the direction authorized, the movement must not exceed 20 MPH for freight trains and 30 MPH for passenger trains.

Question 46: An engineer finishes a radio conversation with the dispatcher and no further response is expected. Which procedural word should the engineer use to end the final transmission?

Out (Correct answer)
Over
Over and Out
Roger

Correct answer: Out

According to GCOR Rule 2.5, the word "OUT" is used to signify that the communication is complete and no response is expected. "Over" is used when a response is expected. The phrase "Over and Out" is contradictory and incorrect procedure.

Question 47: Under GCOR, when must a crew initiate an emergency stop?

Only when a signal displays stop indication
Whenever a condition exists that could cause injury, death, or equipment damage if not stopped (Correct answer)
When speed exceeds the authorized maximum by more than 10 mph
Only when ordered by the dispatcher

Correct answer: Whenever a condition exists that could cause injury, death, or equipment damage if not stopped

GCOR requires crews to initiate an emergency stop any time they observe a condition that could result in injury, death, or significant equipment damage.

Question 48: A train crew is preparing for a switching operation in a complex yard. Before beginning the work, what critical safety activity must they perform together?

Conduct a job briefing to discuss the plan and potential hazards. (Correct answer)
Ensure the lead locomotive has been recently washed.
Check the locomotive's fuel level.
Review the latest stock market report.

Correct answer: Conduct a job briefing to discuss the plan and potential hazards.

Conducting a job briefing is a fundamental safety practice. It ensures all crew members understand the planned movements, their individual responsibilities, and any potential hazards involved in the task, which is essential for safe and coordinated work.

Question 49: A yard crew is leaving a cut of cars unattended on a track. According to GCOR 7.6, what must be done to secure the equipment?

The cars must be coupled to a locomotive with its brakes set.
A sufficient number of hand brakes must be applied to prevent movement. (Correct answer)
Verbal notification to the yardmaster is sufficient.
Only the automatic air brakes must be applied.

Correct answer: A sufficient number of hand brakes must be applied to prevent movement.

GCOR Rule 7.6 states, 'Do not depend on air brakes to hold a train, engine, or cars in place when left unattended. Apply a sufficient number of hand brakes to prevent movement.' If hand brakes are inadequate, wheels must be blocked.

Question 50: A train crew hears the words "EMERGENCY, EMERGENCY, EMERGENCY" broadcast over the radio. According to GCOR, what is the required action for all other employees listening on that channel?

Acknowledge the transmission by saying "Roger Emergency."
Continue with normal duties but monitor the radio for instructions.
Give absolute priority to the communication and refrain from transmitting. (Correct answer)
Switch to a secondary channel to keep it clear for the emergency.

Correct answer: Give absolute priority to the communication and refrain from transmitting.

GCOR Rule 2.10 states that all employees must give absolute priority to an emergency communication. Unless they are directly involved in answering or assisting with the emergency, they must not transmit on the channel until they are certain no interference will result.

Question 51: Which of the following is a prohibited radio transmission according to GCOR?

Reporting a defect found during a roll-by inspection.
Transmitting unidentified, unnecessary, or profane language. (Correct answer)
Using the radio to give hand signals when visibility is poor.
Informing another crew member about the aspect of an upcoming signal.

Correct answer: Transmitting unidentified, unnecessary, or profane language.

GCOR Rule 2.11, "Prohibited Transmissions," explicitly forbids transmitting unnecessary or unidentified communications, as well as using indecent or profane language over the radio. Radio channels are for professional, safety-critical communication only.

Question 52: A train is operating within Yard Limits. What is the primary method of authorizing movement on the main track within these limits?

A clear signal indication from a block signal.
A track warrant issued by the dispatcher.
The presence of a 'Yard Limit' sign itself serves as authority. (Correct answer)
Verbal permission from the yardmaster.

Correct answer: The presence of a 'Yard Limit' sign itself serves as authority.

GCOR Rule 6.13, 'Yard Limits,' states that within yard limits, trains or engines are authorized to use the main track not protecting against other trains or engines. The rule itself, indicated by timetable and signs, provides the authority, with the key stipulation that all movements must be made at restricted speed.

Question 53: What is a controlled siding?

A siding within CTC or interlocking limits where a signal indication authorizes the siding's use (Correct answer)
A siding within CTC or interlocking limits where electric lock switches authorize the siding's use
A siding within CTC or interlocking limits where hand signals authorize the siding's use
A siding within CTC where a distant signal indication authorizes the siding use

Correct answer: A siding within CTC or interlocking limits where a signal indication authorizes the siding's use

Explanation: A controlled siding refers to a siding within CTC or interlocking limits where a signal indication is required to authorize the use of the siding. This means that train operators must receive a specific signal indication before using the siding, ensuring the safe and controlled movement of trains on the tracks.

Question 54: According to GCOR, when a crew member observes fire on the train, what is the immediate required action?

Reduce speed and attempt to identify the source while moving
Stop the train immediately and fight the fire with onboard extinguishers
Continue to the next station to access fire suppression equipment
Stop the train, protect the movement, and notify the dispatcher while evacuating if necessary (Correct answer)

Correct answer: Stop the train, protect the movement, and notify the dispatcher while evacuating if necessary

GCOR requires the crew to stop the train, protect the movement, notify the dispatcher, and evacuate personnel if the fire warrants it.

Question 55: A train has been given authority to proceed on a main track where a block system is in effect. If the train stops or its speed is reduced below 10 MPH after passing a proceed signal, what action is required by GCOR Rule 9.9?

Contact the dispatcher immediately for new instructions.
Wait for a following train to pass before proceeding.
Reverse to the last signal and get a new indication.
Proceed at restricted speed until the next signal is visible and displays a proceed indication. (Correct answer)

Correct answer: Proceed at restricted speed until the next signal is visible and displays a proceed indication.

GCOR Rule 9.9, 'Train Delayed Within a Block,' specifies that if a train that entered a block on a proceed indication stops or slows below 10 MPH, it must then proceed at restricted speed until the next signal is visible and that signal displays a proceed indication.

Question 56: A train receives a track warrant with Box 7 checked: 'Not in effect until after the arrival of Train XYZ at Dover.' What action must the crew take?

Contact the dispatcher for verbal permission to depart.
Depart immediately and clear the main track before Train XYZ arrives.
Proceed at restricted speed until Train XYZ is met.
Must not act on their authority until they have confirmed Train XYZ has arrived at Dover. (Correct answer)

Correct answer: Must not act on their authority until they have confirmed Train XYZ has arrived at Dover.

A track warrant with Box 7 checked creates a conditional authority. The authority granted by the warrant cannot be used, and the train cannot enter the limits, until the specified train (Train XYZ) has arrived at the designated location (Dover). This is a common method for arranging meets between trains in TWC territory.

Question 57: Under which circumstance must a train crew receive a new track warrant to alter their existing limits?

When the limits or instructions of the original warrant need to be changed. (Correct answer)
When the dispatcher verbally advises a change.
When they report clear of a portion of their limits.
When they are delayed within their limits.

Correct answer: When the limits or instructions of the original warrant need to be changed.

According to GCOR Rule 14.11, 'Changing Track Warrants,' if the limits or instructions of a track warrant need to be changed, a new track warrant must be issued that voids the previous one. Employees are explicitly forbidden from altering a warrant in any other manner.

Question 58: According to GCOR, if a train experiences a runaway condition on a descending grade, what is the required action?

Reduce throttle to idle and rely on dynamic brakes
Alert the dispatcher and attempt to reach a siding
Apply emergency brakes, sound the horn continuously, and notify the dispatcher immediately (Correct answer)

Correct answer: Apply emergency brakes, sound the horn continuously, and notify the dispatcher immediately

GCOR requires the engineer to apply emergency brakes, sound the horn continuously to warn others, and notify the dispatcher immediately of a runaway condition.

Question 59: Who is the employee assigned to operate a CTC or interlocking control machine?

Control Operator (Correct answer)
Controller
Clerk Operator
Conductor

Correct answer: Control Operator

Explanation: A control operator is an employee assigned to operate a CTC or interlocking control machine. They are responsible for controlling and monitoring the movement of trains, ensuring the safe and efficient operation of the railway system. They have the authority to control signals, switches, and other equipment to maintain the flow of train traffic. Control operators play a crucial role in maintaining the safety and smooth functioning of the railway network.

Question 60: An employee has finished using a hand-operated main track switch for a switching move. After the entire movement is clear of the switch, what is the final required action regarding the switch's position?

Leave the switch lined for the track last used.
Notify the train dispatcher of the switch's current position.
Place a red flag at the switch stand to indicate it was used.
Line and lock the switch for the main track. (Correct answer)

Correct answer: Line and lock the switch for the main track.

GCOR Rule 8.3 states that the normal position of a main track switch is for main track movement and it must be lined and locked in that position after use, unless specific exceptions apply (such as being attended or under dispatcher authority).

Question 61: A crew must leave a cut of 20 cars unattended on a track with a slight grade. According to GCOR 7.6, which of the following is the most critical and required action?

Leave the automatic air brakes fully applied and depart.
Chock the wheels of the lead car and notify the dispatcher.
Apply the hand brake on the first and last car only.
Apply a sufficient number of hand brakes and then release the air brakes to verify the equipment is secure. (Correct answer)

Correct answer: Apply a sufficient number of hand brakes and then release the air brakes to verify the equipment is secure.

GCOR 7.6 explicitly prohibits depending on air brakes alone to secure unattended equipment, as they can leak off over time. The rule requires applying a "sufficient number" of hand brakes to prevent movement and then verifying they are holding by releasing the air brakes.

Question 62: Under GCOR, what action is required when a crew member becomes incapacitated and unable to perform their duties?

The remaining crew member must stop the train and notify the dispatcher (Correct answer)
The incapacitated member must be removed at the next crossing
The train must continue to maintain schedule while help is summoned
The remaining crew may continue to the next stop if less than 10 miles away

Correct answer: The remaining crew member must stop the train and notify the dispatcher

GCOR requires the remaining crew member to stop the train and immediately notify the dispatcher when a crew member becomes incapacitated.

Question 63: Under GCOR, what must a locomotive engineer do if the automatic train stop or train control device activates unexpectedly?

Reduce speed to 30 mph and notify the dispatcher
Stop the train, report the activation, and not proceed until authorized (Correct answer)
Reset it immediately and continue
Apply independent brakes and continue at 15 mph

Correct answer: Stop the train, report the activation, and not proceed until authorized

An unexpected activation of automatic train stop or train control requires the engineer to stop the train, report the incident, and await authorization before proceeding.

Question 64: According to GCOR, what is required before a locomotive is moved in a yard or terminal where it has been set out?

The locomotive must be inspected and the brakes released by a qualified employee (Correct answer)
The locomotive must be fueled and sanded before any movement
A dispatcher clearance must be obtained regardless of track authority
A written work order must be completed and filed with the yardmaster

Correct answer: The locomotive must be inspected and the brakes released by a qualified employee

Before moving a locomotive that has been set out, a qualified employee must inspect it and ensure the brakes are properly released.

Question 65: Your train is approaching an interlocking and the governing signal displays a red over green aspect. What action should you take?

Stop immediately; the signal is improperly displayed.
Proceed prepared to stop at the next signal.
Proceed at normal speed as the route is clear.
Proceed on the diverging route at the prescribed speed through the turnout. (Correct answer)

Correct answer: Proceed on the diverging route at the prescribed speed through the turnout.

A red over green aspect is a 'Diverging Clear' signal. It indicates that the route is lined for a diverging movement and the train may proceed through the turnout at the speed specified in the timetable or special instructions. The track beyond the interlocking is clear.

Question 66: A train is authorized to enter a yard track protected by a derail. Before the train occupies the track, what must be done with the derail?

The train must stop and wait for a five-minute interval before proceeding.
The derail must be inspected and confirmed to be in the derailing position.
The train dispatcher must be contacted for verbal permission to pass the derail.
The derail must be removed from the rail or placed in the non-derailing position. (Correct answer)

Correct answer: The derail must be removed from the rail or placed in the non-derailing position.

The purpose of a derail is to protect another track (often the main track) from an unauthorized movement. The derail must be placed in the non-derailing position to allow equipment to safely enter the track it protects.

Question 67: According to GCOR, what is the first action a crew must take when a derailment occurs?

Protect the scene and notify the dispatcher immediately (Correct answer)
Conduct a damage assessment before notifying anyone
Attempt to re-rail the equipment
Move the train to the nearest siding

Correct answer: Protect the scene and notify the dispatcher immediately

GCOR requires that following any derailment, the crew's first action is to protect the scene to prevent further incidents and immediately notify the dispatcher.

Question 68: A conductor is initiating a non-emergency radio call to the dispatcher. What is the correct format for the initial transmission?

"Dispatcher, this is train XYZ, over."
"(Railroad) Dispatcher from (Railroad) Train XYZ at MP 123, over." (Correct answer)
"This is XYZ conductor, need to talk to the dispatcher, over."
"Train XYZ to the dispatcher at Omaha, over."

Correct answer: "(Railroad) Dispatcher from (Railroad) Train XYZ at MP 123, over."

GCOR Rule 2.2, "Required Identification," specifies that transmissions must begin by identifying the party being called, followed by the calling party's own identification, which includes the railroad initials, train ID, and location. This ensures there is no confusion about who is talking to whom.

Question 69: Under what specific condition may a train dispatcher issue a track warrant to a train that will have overlapping limits with men or equipment?

If the train crew verbally agrees to look out for the men and equipment.
When all trains authorized are notified and instructed to move at restricted speed within the overlapping limits. (Correct answer)
Only if the men or equipment are also operating a train.
Never, it is strictly prohibited to have overlapping limits between a train and men or equipment.

Correct answer: When all trains authorized are notified and instructed to move at restricted speed within the overlapping limits.

GCOR Rule 14.5 allows for a track warrant to be issued with overlapping limits for a train and men or equipment, provided that all trains involved are notified of the men or equipment and are instructed to move at restricted speed through the shared limits. The rule also requires that the employee in charge of the men or equipment is informed about the trains.

Question 70: When a train dispatcher transmits a mandatory directive by radio, what is the first action the copying employee must take after the dispatcher has finished speaking?

Acknowledge receipt by saying "Copy" or "Roger."
Immediately repeat the directive back to the dispatcher word-for-word. (Correct answer)
Write down the time and the dispatcher's name.
Ask the conductor to verify the contents of the directive.

Correct answer: Immediately repeat the directive back to the dispatcher word-for-word.

GCOR Rule 2.3, "Repetition," requires that employees who receive transmissions containing information, instructions, or advice that could affect safety must repeat them back to the sender. This ensures the directive was copied and understood correctly before being acted upon.

Question 71: According to GCOR, what speed is defined as 'restricted speed'?

A speed not exceeding 10 mph at all times
A speed that allows stopping within the range of vision, not to exceed 15 mph (Correct answer)
A speed not exceeding 20 mph
A speed that allows stopping within half the range of vision, not to exceed 20 mph

Correct answer: A speed that allows stopping within the range of vision, not to exceed 15 mph

Restricted speed under GCOR means a speed that allows the train to stop within the range of vision, and in no case exceeding 15 mph.

Question 72: In case of doubt or uncertainty:

Only take the safe course if your supervisor instructs you to.
Take the safe course (Correct answer)
Take the safe course only if it doesn't cause a delay.
Contact the train dispatcher for instructions

Correct answer: Take the safe course

Explanation: This means that whenever there is doubt or uncertainty, it is advisable to choose the safer option. However, it is important to note that this should only be done if it does not cause any delay. This answer implies that safety should be prioritized, but not at the expense of efficiency or productivity.

Question 73: According to GCOR, what must an engineer do before leaving a locomotive unattended?

Secure the locomotive so it cannot move and leave it in a safe condition (Correct answer)
Apply the independent brake and lock the cab
Notify the dispatcher and leave the engine running at idle
Place the reverser in the forward position and apply full throttle lockout

Correct answer: Secure the locomotive so it cannot move and leave it in a safe condition

Before leaving a locomotive unattended, the engineer must secure it so it cannot move and ensure it is in a safe condition to protect against unintended movement.

Question 74: A train crew receives a track warrant that includes the instruction in Box 8: 'Hold main track at last named point.' If the last named point is a station with a siding, what does this instruction require?

The train's authority extends to and includes the last siding switch.
The train must stop before the first siding switch at the station.
The train may proceed through the station on the main track without stopping.
The train's authority extends to but does not include the last siding switch. (Correct answer)

Correct answer: The train's authority extends to but does not include the last siding switch.

According to GCOR Rule 14.2 (B), when a track warrant includes the instruction 'Hold main track at last named point,' the train's authority extends up to, but does not include, the last siding switch at that location. This prevents the train from fouling the switch that an opposing train might need to use.

Question 75: According to GCOR Rule 1.1, what is the most important element in performing duties?

Punctuality
Efficiency
Following orders
Safety (Correct answer)

Correct answer: Safety

GCOR Rule 1.1 explicitly states, 'Safety is the most important element in performing duties. Obeying the rules is essential to job safety and continued employment.' This establishes safety as the primary concern above all other aspects of work.

Question 76: A series of consecutive blocks governed by block signals where the signals are activated by a train or by certain conditions that affect the block. This system is called:

Automatic block signal system (ABS) (Correct answer)
Centralized traffic control (CTC)
Track warrant control (TWC)
Absolute block signal system (ABSS)

Correct answer: Automatic block signal system (ABS)

Explanation: An automatic block signal system (ABS) is a system where block signals are activated by a train or certain conditions that affect the block. In this system, consecutive blocks are governed by block signals, ensuring safe and efficient train operations. Centralized traffic control (CTC) is a different system where a centralized control center manages train movements. Track warrant control (TWC) is a system where train movements are authorized by track warrants. Absolute block signal system (ABSS) is a term used to describe a system where each block is protected by a fixed signal and trains must receive permission to enter the block. However, none of these systems fully match the given description except for the automatic block signal system (ABS).

Question 77: When must both switches of a hand-operated crossover be opened before starting a crossover movement?

Only when the crossover connects to a siding.
Both switches must be opened before the movement starts. (Correct answer)
Only when the movement is on a main track.
At all times, unless used for continuous switching by one crew.

Correct answer: Both switches must be opened before the movement starts.

GCOR Rule 8.12 requires that both switches of a crossover must be opened before a crossover movement starts. The movement must be completed before either switch is returned to its normal position. This ensures the route is completely lined and secured.

Question 78: A train is operating in CTC territory and stops at a control point with an absolute signal displaying 'Stop'. The crew needs to make a reverse movement just inside the block they came from to set out a car. According to GCOR, what is the first required action?

Proceed through the stop signal, then initiate the reverse movement.
Immediately begin the reverse movement at restricted speed, as it's within the same block.
Wait for a more favorable signal indication before reversing.
Obtain permission from the control operator before making any reverse movement. (Correct answer)

Correct answer: Obtain permission from the control operator before making any reverse movement.

GCOR Rule 6.4.2 states that if a movement stops while the trailing end is between the outer opposing absolute signals of a control point, it must not change direction without permission from the control operator. Since the train is at a control point, permission is mandatory before reversing, even if the movement is within the same signaled block.

Question 79: According to GCOR, when must the locomotive horn be sounded at a public grade crossing?

At all times when the locomotive is moving through a crossing
Only during nighttime operations or in poor visibility conditions
Only when active warning devices are not functioning
At approximately one-quarter mile before the crossing and until the locomotive occupies the crossing (Correct answer)

Correct answer: At approximately one-quarter mile before the crossing and until the locomotive occupies the crossing

GCOR requires the horn to be sounded beginning approximately one-quarter mile before a public grade crossing and continuing until the locomotive occupies the crossing.

Question 80: A notice of conditions affecting train movement is:

A track bulletin (Correct answer)
A train location manual
A train lineup
A train ledger

Correct answer: A track bulletin

Explanation: A track bulletin is a notice that provides information about conditions that may affect train movement. It includes details about track maintenance, repairs, or any other factors that could impact the schedule or safety of train operations. Train personnel rely on track bulletins to stay informed and make necessary adjustments to ensure smooth and efficient train movement. A train ledger, train location manual, and train lineup are not specifically related to providing information about conditions affecting train movement, making them incorrect options.

Question 81: A train has authority on a track warrant from MP 10 to MP 30. After the entire train passes MP 20, the conductor reports this to the train dispatcher. What is the status of the train's authority?

A new track warrant is required to proceed to MP 30.
The entire warrant from MP 10 to MP 30 remains in effect.
The authority is considered void up to MP 20. (Correct answer)
The authority is now void between MP 20 and MP 30.

Correct answer: The authority is considered void up to MP 20.

GCOR Rule 14.3 states that when a crew member informs the train dispatcher that the entire train has passed a specific point, the track warrant authority is considered void up to that point. The authority from MP 20 to MP 30 remains in effect.

Question 82: Under GCOR, what does a crew do when a train encounters an unexpected low-hanging obstruction over the track?

Reduce to 10 mph and proceed with caution
Proceed at restricted speed while ducking
Contact the dispatcher and then proceed
Stop immediately and protect the obstruction before any action is taken (Correct answer)

Correct answer: Stop immediately and protect the obstruction before any action is taken

GCOR requires the crew to stop immediately when an unexpected obstruction is encountered and protect the scene before taking further action.

Question 83: Under GCOR, when is a crew authorized to pass a switch that is not properly lined without specific authority to do so?

When visibility confirms the track is clear for 500 feet
When the conductor personally lines and secures the switch
When the dispatcher verbally confirms the switch position
Never; improperly lined switches require specific authority before movement (Correct answer)

Correct answer: Never; improperly lined switches require specific authority before movement

GCOR prohibits any movement through an improperly lined switch without specific authority — verbal confirmation alone is insufficient.

Question 84: According to GCOR, when must a locomotive's number plates or identification be legible?

Only during daylight operations
Only when the locomotive is in a designated reporting location
At all times while the locomotive is in service (Correct answer)
Only when the locomotive is in lead position

Correct answer: At all times while the locomotive is in service

Locomotive identification must be legible at all times while the unit is in service to allow proper identification for operational and safety purposes.

Question 85: According to GCOR Rule 8.2, who bears the ultimate responsibility for the position of a hand-operated switch while it is in use?

The conductor of the train.
The employee who is operating the switch. (Correct answer)
The train dispatcher.
The locomotive engineer.

Correct answer: The employee who is operating the switch.

GCOR Rule 8.2 explicitly states that the employee handling or operating the switch is responsible for its position. This is a rule of personal responsibility.

Question 86: Under GCOR Rule 8.2, who is specifically assigned responsibility for the position of a hand-operated switch while it is in use?

The employee operating the switch. (Correct answer)
The train dispatcher.
The engineer operating the locomotive.
The conductor of the train.

Correct answer: The employee operating the switch.

GCOR Rule 8.2 clearly states, 'The employee operating the switch or derail is responsible for the position of the switch or derail in use.' This places direct responsibility on the individual physically manipulating the switch.

Question 87: Under GCOR, what must be done before a train movement resumes following an emergency stop?

A written slow order must be obtained
An inspection must be made and the cause of the emergency must be determined (Correct answer)
The dispatcher must be notified and a release must be received
The conductor must walk the entire train

Correct answer: An inspection must be made and the cause of the emergency must be determined

GCOR requires that before resuming movement after an emergency stop, an inspection must be conducted and the reason for the stop must be identified and resolved.

Question 88: Who is responsible for the safety of their train and observance of the rules?

The conductor
The engineer
The yardmaster
The conductor and engineer (Correct answer)

Correct answer: The conductor and engineer

Explanation: The conductor and engineer are responsible for the safety of their train and observance of the rules. The conductor is in charge of managing the train's crew, ensuring that the train operates safely, and enforcing safety protocols. The engineer, on the other hand, is responsible for operating the train and adhering to the rules and regulations of the railway system. Together, they work as a team to ensure the safety of the train and its passengers.

A qualified crew member must be posted as a lookout at the leading end
The headlight on the leading end must be illuminated (Correct answer)
Speed must be reduced to no more than 10 mph at all times
The dispatcher must be notified and movement limited to yard tracks only

Correct answer: The headlight on the leading end must be illuminated

When a locomotive is operated long hood or cab forward, the headlight on the leading end must be illuminated to provide visibility and warning to others.

Question 90: While operating in signaled territory, your train passes a signal displaying a flashing yellow aspect. What is the name and indication of this signal?

Advance Approach: Proceed prepared to stop at the second signal.
Clear: Proceed at maximum authorized speed.
Approach Restricting: Proceed prepared to pass the next signal at restricted speed. (Correct answer)
Diverging Approach: Proceed on a diverging route prepared to stop at the next signal.

Correct answer: Approach Restricting: Proceed prepared to pass the next signal at restricted speed.

A flashing yellow aspect is an 'Approach Restricting' signal. The indication is to proceed prepared to pass the next signal at restricted speed. This tells the engineer that the block ahead is clear, but the next signal will require them to enter a block under restricted speed conditions.

Question 91: Under GCOR, who is permitted to establish, control, and release working limits for the purpose of on-track safety?

Only a qualified Roadway Worker in Charge (RWIC). (Correct answer)
A designated member of the train crew operating in the vicinity.
The train dispatcher for the territory where the work is being performed.
Any employee who has completed the annual roadway worker protection training.

Correct answer: Only a qualified Roadway Worker in Charge (RWIC).

Only a properly qualified Roadway Worker in Charge (RWIC) has the authority and responsibility to establish, have control over, and ultimately release working limits. This ensures a single point of contact and control for the safety of the work group.

Question 92: In a situation of doubt or uncertainty regarding a rule or instruction, what is the required course of action under GCOR Rule 1.1.1?

Proceed with the most efficient option.
Wait for the dispatcher to provide clarification, regardless of delay.
Ask a more experienced, but not supervisory, co-worker.
Take the safe course. (Correct answer)

Question 96: Crossings that intersect at the same level are called:

Level crossings
Overhead crossings
Bridge crossings
Crossings at grade (Correct answer)

Correct answer: Crossings at grade

Explanation: Crossings that intersect at the same level are called "crossings at grade". This term is commonly used in transportation and refers to intersections where two or more roads or railroad tracks cross each other at the same elevation. These crossings can be dangerous as they often require vehicles or pedestrians to cross the path of oncoming traffic. Therefore, it is important to exercise caution and follow traffic signals and signs when approaching crossings at grade.

Question 97: A train crew is preparing to couple to a stationary cut of cars. What is the maximum permissible coupling speed according to GCOR 7.4?

A speed that permits stopping within half the range of vision.
Restricted Speed
10 MPH
4 MPH (Correct answer)

Question 99: When operating a locomotive with a defective sand system, what restriction applies under GCOR?

The locomotive must be the rear unit in the consist
Speed must be reduced to account for potentially reduced adhesion (Correct answer)
No restriction applies if the train tonnage is within rating
The locomotive may not be used as the lead unit on grades exceeding 1%

Correct answer: Speed must be reduced to account for potentially reduced adhesion

A defective sand system reduces wheel-rail adhesion capability, requiring a speed reduction to account for the increased risk of wheel slip or slide.

Question 100: Under GCOR, what is the correct procedure when an engineer notices a locomotive fuel level is critically low during a trip?

Notify the train dispatcher so arrangements can be made for refueling (Correct answer)
Apply the emergency brake and request immediate fuel delivery
Continue to the destination as fuel is the railway's responsibility, not the crew's
Immediately shut down all non-essential electrical systems and continue

Correct answer: Notify the train dispatcher so arrangements can be made for refueling

When fuel is critically low, the engineer must notify the train dispatcher so that arrangements can be made for refueling before the locomotive runs out of fuel.

Question 101: After a crew member applies hand brakes on a cut of cars and releases the air, they observe the cars begin to roll slightly. What is the immediate and correct action required by GCOR?

Notify the dispatcher that the hand brakes are defective.
Re-apply the air brakes and leave them applied.
Place a single wheel chock under the nearest wheel.
Apply additional hand brakes until the equipment is fully secured against movement. (Correct answer)

Correct answer: Apply additional hand brakes until the equipment is fully secured against movement.

The observation of movement after releasing the air brakes is a failed test, indicating that an insufficient number of hand brakes have been applied. The correct procedure is to continue applying hand brakes and re-testing until it is proven that the hand brakes alone are sufficient to hold the equipment.

Question 102: Which of the following is strictly prohibited for an employee on duty or on company property according to GCOR Rule 1.5?

Consuming a caffeinated beverage.
Taking a prescribed medication as directed by a doctor.
Possessing an alcoholic beverage. (Correct answer)
Using a company-supplied electronic device for work purposes.

Correct answer: Possessing an alcoholic beverage.

GCOR Rule 1.5 is clear: 'The use or possession of alcoholic beverages while on duty or on company property is prohibited.' While rules exist for medication and electronic devices, the outright possession of alcohol is forbidden.
