Question 4: According to GCOR, when an emergency requires the track to be protected against other movements, who may authorize a crew to foul the track for protection purposes?

The conductor must receive written authority first
The crew may act on their own authority to protect the track in an emergency (Correct answer)
Only the chief dispatcher may authorize track fouling for protection
A track supervisor must be present before protection can be established

Correct answer: The crew may act on their own authority to protect the track in an emergency

In an emergency, GCOR authorizes the crew to act on their own initiative to protect the track and prevent additional accidents without waiting for outside authorization.

Question 5: Under which circumstance must a train crew receive a new track warrant to alter their existing limits?

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

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 6: 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 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 train must stop and wait for a five-minute interval before proceeding.
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 7: What action is required when a locomotive's dynamic brakes become inoperative during a descending grade operation?

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

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 8: 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?

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

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 9: 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 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.
The crew must open the switch and wait 5 minutes to establish signal protection.
The crew must provide flag protection in both directions.

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

Diverging Approach: Proceed on a diverging route prepared to stop at the next signal.
Approach Restricting: Proceed prepared to pass the next signal at restricted speed. (Correct answer)
Clear: Proceed at maximum authorized speed.
Advance Approach: Proceed prepared to stop at the second 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 11: According to GCOR Rule 1.1, what is the most important element in performing duties?

Safety (Correct answer)
Efficiency
Following orders

Question 15: A train is operating within Yard Limits. What is the primary method of authorizing movement on the main track within these limits?

The presence of a 'Yard Limit' sign itself serves as authority. (Correct answer)
A clear signal indication from a block signal.
A track warrant issued by the dispatcher.
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 16: 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.
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)
Wait for a following train to pass before proceeding.

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 17: A movement opposite the authorized direction is a :

Backup movement
Movement not allowed
Reverse movement (Correct answer)
Movement of cars ahead of the engine

Correct answer: Reverse movement

Explanation: A movement opposite the authorized direction refers to a reverse movement, where the object or vehicle moves in the opposite direction of the authorized or intended path.

A sufficient number of hand brakes must be applied to prevent movement. (Correct answer)
The cars must be coupled to a locomotive with its brakes set.

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 19: 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.
Reverse movements are not permitted in ABS territory.
In CTC, signal indications authorize train movement, while in ABS, signals provide protection but do not authorize movement. (Correct answer)
In ABS, trains can proceed without any form of track authority.

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

The train must continue to maintain schedule while help is summoned
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 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.

Request the dispatcher to remotely line the crossover switches.

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 28: 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:

Track warrant control (TWC)
Centralized traffic control (CTC)
Automatic block signal system (ABS) (Correct answer)
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 29: 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

Continue to the destination as fuel is the railway's responsibility, not the crew's
Notify the train dispatcher so arrangements can be made for refueling (Correct answer)

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 34: 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?

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.
Acknowledge receipt by saying "Copy" or "Roger."

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 35: 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.
A new track warrant must be issued that includes the instruction 'Track Warrant No. ___ is void'. (Correct answer)
The crew can verbally agree with the dispatcher to void the warrant.
The warrant automatically becomes void after a fixed period of two hours.

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 36: 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.
Only if the men or equipment are also operating a train.
When all trains authorized are notified and instructed to move at restricted speed within the overlapping limits. (Correct answer)
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.

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

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 40: 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.
Wait for a more favorable signal indication before reversing.
Obtain permission from the control operator before making any reverse movement. (Correct answer)
Immediately begin the reverse movement at restricted speed, as it's within the same block.

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

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

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 54: When a locomotive cab is not equipped with a working windshield wiper on the engineer's side during precipitation, what does GCOR require?

The train may continue at restricted speed until the next terminal
Speed must be reduced by 50% of the maximum authorized speed
The locomotive must be set out at the next available location (Correct answer)
The conductor must act as a lookout from an exterior position

Correct answer: The locomotive must be set out at the next available location

A non-functional windshield wiper on the engineer's side impairs visibility and requires the locomotive to be set out at the next available location for repair.

Question 55: 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 locomotive engineer.
The employee who is operating the switch. (Correct answer)
The train dispatcher.
The conductor of the train.

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 56: 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?

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

Correct answer: Take the safe course.

GCOR Rule 1.1.1, 'Maintaining a Safe Course,' states, 'In case of doubt or uncertainty, take the safe course.' This principle overrides all other considerations, such as speed or efficiency, to ensure safety.

Question 57: When operating on another railroad, unless otherwise instructed, employees will be governed by:

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

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 58: According to GCOR, what action must be taken before a train passes over a track that has been reported as suspected of having a defect?

Stop and inspect the track before proceeding
Proceed at restricted speed
Reduce speed to 10 mph and proceed
Obtain specific authority from the dispatcher or track authority (Correct answer)

Correct answer: Obtain specific authority from the dispatcher or track authority

GCOR requires specific authority from the dispatcher or track authority before a train proceeds over track suspected of having a defect.

Question 59: 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?

Over
Out (Correct answer)
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 60: When must the conductor inform the engineer of a restriction?

After the train passes two stations in advance of the restriction, but at least after the train passes the last station
When leaving the initial station
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)

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 61: A roadway worker is assigned to work alone and must foul the track. What is this worker referred to as, and what must they do at the start of their duty period?

A 'Field Inspector', and they must place red flags 2 miles in each direction before starting work.
A 'Lone Worker', and they must communicate with a supervisor to receive an on-track safety job briefing. (Correct answer)
A 'Track Patroller', and they must get a track bulletin listing all train movements.
A 'Solo Employee', and they must wait for the first train to pass before fouling the track.

Correct answer: A 'Lone Worker', and they must communicate with a supervisor to receive an on-track safety job briefing.

A roadway worker assigned to work alone is termed a 'Lone Worker'. Federal regulations (49 CFR § 214.315(e)) require that each lone worker communicate with a supervisor or another designated employee at the beginning of each duty period to receive an on-track safety job briefing and discuss their planned itinerary and safety procedures.

Question 62: If a locomotive's headlight fails during a trip, what does GCOR generally require?

Stop immediately and not move until repaired
Continue the trip at reduced speed not to exceed 30 mph
Proceed only with dispatcher permission and at restricted speed
Report the defect at the next terminal and take the locomotive out of service (Correct answer)

Correct answer: Report the defect at the next terminal and take the locomotive out of service

A defective headlight must be reported at the next terminal and the locomotive taken out of service, as proper illumination is required for safe operation.

Question 63: According to GCOR, after an emergency brake application is made, when may the engineer release the brakes?

When the train speed drops below 20 mph
Only after the train has come to a complete stop and the situation is assessed (Correct answer)
After receiving dispatcher permission via radio
Immediately after the hazard is passed

Correct answer: Only after the train has come to a complete stop and the situation is assessed

GCOR requires the emergency brake application to be maintained until the train has come to a complete stop and the crew has assessed the situation.

Question 64: According to GCOR, what speed must be observed when passing a roadway worker's on-track equipment that has been given 'clear of the movement' notification?

Restricted speed
10 mph
Normal timetable speed
20 mph (Correct answer)

Correct answer: 20 mph

Even after on-track equipment has been cleared, GCOR requires trains to pass at no more than 20 mph to ensure worker safety.

Question 65: 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?

They must stop before the absolute signal at CP 85 and get separate permission to pass it.
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)

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

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 headlight must be set to dim and flashing.
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 67: Under GCOR, after a train is involved in a collision, when may the crew move the equipment without specific authority?

Immediately to clear the main track
Only if movement is necessary to protect life or prevent further damage (Correct answer)
Only with written authority from the chief dispatcher
After a 30-minute waiting period

Correct answer: Only if movement is necessary to protect life or prevent further damage

GCOR only permits movement of collision-involved equipment without specific authority when such movement is necessary to protect human life or prevent additional damage.

Question 68: According to GCOR, what must a crew do if they experience a loss of communication ability during an emergency?

Continue normal operations until communication is restored
Proceed to the nearest station and report in person
Use all available means to communicate the emergency, including visual signals (Correct answer)
Stop the train and wait for communication to be restored

Correct answer: Use all available means to communicate the emergency, including visual signals

When communication is lost during an emergency, GCOR requires crews to use all available means to alert others, including hand signals, horn signals, and fusees.

Question 69: 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 70: 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)
Notify the dispatcher and leave the engine running at idle
Apply the independent brake and lock the cab
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 71: When a GCOR train must stop and the engineer cannot stop within half the range of vision, what action is required?

Stop immediately regardless of consequences
Reduce speed and call the dispatcher
Apply emergency brakes and sound the horn (Correct answer)
Sound the horn and proceed at 10 mph

Correct answer: Apply emergency brakes and sound the horn

When unable to stop within half the range of vision, GCOR requires the engineer to apply emergency brakes and sound the horn to warn others.

Question 72: 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?

Report it by the first available means of communication. (Correct answer)
Only report it if a train is currently approaching the defect.
Fix the defect personally if the tools are available.
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 73: According to GCOR, what is the first action a crew must take when a derailment occurs?

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

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

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

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

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

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

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

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 77: 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?

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

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

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

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

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 80: According to GCOR, what is the maximum speed allowed when moving against the current of traffic on a double main track without a specific authority?

20 mph
40 mph
10 mph (Correct answer)
30 mph

Correct answer: 10 mph

GCOR restricts movement against the current of traffic on double main track to a maximum of 10 mph unless specific authority is granted.

Question 81: Under GCOR, who is responsible for the safe and efficient operation of the locomotive consist?

Both the engineer and conductor share equal responsibility (Correct answer)
The train dispatcher, who controls all movements
The engineer alone, as the qualified locomotive operator
The conductor, as the employee in charge of the train

Correct answer: Both the engineer and conductor share equal responsibility

Under GCOR, both the engineer and conductor share responsibility for the safe and efficient operation of the train and locomotive consist.

Question 82: Under GCOR, after a crew has stopped to protect a scene, how far in advance must protection be placed from the nearest end of the obstruction?

1,000 feet
Sufficient distance to allow stopping a following train (Correct answer)
500 feet
2,500 feet

Correct answer: Sufficient distance to allow stopping a following train

GCOR requires protection to be placed at a sufficient distance in advance of the obstruction to allow an approaching train to stop before reaching it.

Question 83: Under GCOR, what speed restriction applies to a train with defective or inoperative dynamic brakes on grades exceeding a specific percentage?

The train must not exceed 30 mph on any grade
The train must not exceed the speed authorized by the chief mechanical officer or equivalent (Correct answer)
The train must stop and not proceed until repaired
No restriction applies if air brakes are functional

GCOR requires that when dynamic brakes are defective on steep grades, the speed must not exceed what is authorized by the designated mechanical authority.

Question 84: Who is responsible for the safety of their train and observance of the rules?

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

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.

Question 85: Under GCOR, when is a crew authorized to pass a switch that is not properly lined without specific authority to do so?

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

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

Conductor
Controller
Clerk Operator
Control Operator (Correct answer)

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

Possessing an alcoholic beverage. (Correct answer)
Consuming a caffeinated beverage.
Taking a prescribed medication as directed by a doctor.
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.

Question 88: Which of the following actions is explicitly prohibited when a blue signal is displayed on a track, according to GCOR 5.13?

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.
Operating a switch that provides access to 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 89: Which of the following is a prohibited radio transmission according to GCOR?

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

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 90: A roadway work group is protected by a watchman/lookout providing 'Train Approach Warning'. What is the primary responsibility of each roadway worker when the watchman/lookout gives a warning of an approaching train?

To secure all tools and equipment before leaving the track.
To acknowledge the warning by raising a hand signal to the watchman.
To immediately contact the RWIC for further instructions.
To move to a predetermined place of safety and remain there until the train has passed. (Correct answer)

Correct answer: To move to a predetermined place of safety and remain there until the train has passed.

When 'Train Approach Warning' is the method of protection, the system relies on the watchman/lookout providing timely warning and each worker immediately occupying a predetermined place of safety. The first and most critical action is to clear the track to the place of safety. Other actions are secondary to ensuring personal safety from the approaching train.

Question 91: Under GCOR Rule 8.2, who is specifically assigned responsibility for the position of a hand-operated switch while it is in use?

The engineer operating the locomotive.
The employee operating the switch. (Correct answer)
The train dispatcher.
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 92: According to GCOR, when is a crew permitted to exceed the maximum authorized timetable speed?

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

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 93: According to GCOR, what is the indication for a signal displaying a single yellow light, known as an 'Approach' signal?

Proceed at restricted speed.
Proceed prepared to stop at the next signal. Trains exceeding 30 MPH must immediately reduce to that speed. (Correct answer)
Proceed, but be prepared to pass the next signal at a speed not exceeding 40 MPH.
Stop, then proceed at restricted speed.

Correct answer: Proceed prepared to stop at the next signal. Trains exceeding 30 MPH must immediately reduce to that speed.

The 'Approach' signal indication requires the train to be operated in a manner that allows it to be stopped before the next signal. It also imposes an immediate speed reduction for trains traveling faster than a specified speed (often 30 or 40 MPH, depending on the railroad's special instructions, but the core instruction is to prepare to stop).

Question 94: When Yard Limits are in effect within CTC territory, which rule takes precedence for authorizing movement on the main track?

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.
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.

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

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

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 96: According to GCOR, when must a crew report a rough or unusual track condition observed during their run?

Only if it caused a speed reduction
At the end of the trip in the trip report
Only if another train reports the same condition
Immediately to the dispatcher upon observation (Correct answer)

Correct answer: Immediately to the dispatcher upon observation

GCOR requires crews to report rough or unusual track conditions to the dispatcher immediately upon observation, not at the end of the trip.

Question 97: 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?

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)
Leave the automatic air brakes fully applied and depart.

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 98: 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
Stop immediately and protect the obstruction before any action is taken (Correct answer)
Proceed at restricted speed while ducking
Contact the dispatcher and then proceed

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

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 100: 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)
Sound the horn in a specific sequence to warn the work crew.
Proceed at restricted speed upon entering the limits.
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 101: 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.
Line and lock the switch for the main track. (Correct answer)
Place a red flag at the switch stand to indicate it was used.
Notify the train dispatcher of the switch's current position.

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 102: Under GCOR, if a train crew observes a person on or near the track in an emergency situation, what must the engineer do?

Sound the horn and proceed at normal speed
Notify the dispatcher before taking any action
Slow to restricted speed and sound the horn once
Sound the horn continuously and make an emergency brake application if necessary (Correct answer)

Correct answer: Sound the horn continuously and make an emergency brake application if necessary

GCOR requires the engineer to sound the horn continuously as a warning and make an emergency brake application if necessary to prevent injury to persons on or near the track.
