Personal Track Safety (PTS) Exam — Questions and Answers

Question 1: After a near-miss incident involving a communication failure on the track, what is the MOST important immediate action?

Halt work, secure the site, report the near-miss, and investigate the communication failure before resuming (Correct answer)
Continue work after a brief team discussion about what went wrong
Retrain the responsible worker on-site immediately
Document the incident and submit a report at the end of the shift

Correct answer: Halt work, secure the site, report the near-miss, and investigate the communication failure before resuming

A near-miss must trigger an immediate halt, site securing, and formal report so the root communication failure can be identified and corrected before any further risk occurs.

Question 2: What is meant by a 'defined' position of safety on a job briefing?

A position identified and communicated to all workers before work begins (Correct answer)
A position that is at least 50 feet from the nearest track
A position approved by the train dispatcher
Any location the worker judges to be safe in the moment

Correct answer: A position identified and communicated to all workers before work begins

A defined position of safety is one that is identified and communicated to all workers during the job briefing before work commences.

Question 3: What information must a briefing before work near electrified lines ALWAYS include?

Names of all electrical workers on duty that shift
PPE inspection checklist and signing roster only
Voltage levels, type of electrification, exclusion zones, emergency procedures, and designated safe areas (Correct answer)
Train schedule and passenger load only

Correct answer: Voltage levels, type of electrification, exclusion zones, emergency procedures, and designated safe areas

Pre-task briefings near electrified lines must cover voltage, electrification type, exclusion zones, emergency response, and emergency safe areas so every worker can act safely.

Question 4: What is the danger of working on or near electrified lines during foggy or damp weather conditions?

Moisture significantly reduces the electrical resistance of surfaces, increasing the risk of electrical flashover and reducing the safe working distance from energised equipment (Correct answer)
Rain increases the visibility of the third rail, making work safer
Damp conditions have no effect on electrical safety on the railway
Fog reduces the visibility of OLE warning signs only

Correct answer: Moisture significantly reduces the electrical resistance of surfaces, increasing the risk of electrical flashover and reducing the safe working distance from energised equipment

Moisture reduces the electrical resistance of ballast, sleepers, and equipment, increasing the risk of electrical flashover from OLE and reducing the effective safe distance from energised equipment.

Question 5: Which action is required when a worker is injured and must be transported off the right-of-way by emergency vehicle?

Wait for railroad-approved ambulance before moving the victim
Any available vehicle may be used to transport the victim immediately
The victim should walk to the nearest road crossing if able
Track protection must be established before any vehicle enters the right-of-way (Correct answer)

Correct answer: Track protection must be established before any vehicle enters the right-of-way

Any emergency vehicle entering the right-of-way must have proper track protection established to prevent a collision.

Question 6: A foreman discovers a falsified entry in the incident log — a previous worker marked 'no injury' for an event where a colleague was sent to a clinic. What should the foreman do?

Ignore it since the affected worker has already been treated
Cross out the entry and leave a note
Correct the record and report the falsification to safety management (Correct answer)
Remove the page to prevent embarrassment for the crew

Correct answer: Correct the record and report the falsification to safety management

Falsifying safety records is a serious violation; the foreman must correct the record and escalate the falsification to safety management.

Question 7: Which of the following is NOT a responsibility of the COSS during a track safety briefing?

Confirming workers' fitness and understanding of the briefing
Explaining the protection arrangements in place
Describing escape routes and places of safety
Issuing formal possession documents to each worker (Correct answer)

Correct answer: Issuing formal possession documents to each worker

Formal possession documents are held and managed by the PICOP, not distributed by the COSS during a safety briefing.

Question 8: What is the purpose of a 'look-out' in a track safety system?

To check that all workers hold valid PTS cards before access
To liaise with the signaller and update possession boundaries
To watch for approaching trains and warn the work group in time to reach a place of safety (Correct answer)
To record the identity of all workers entering the track area

Correct answer: To watch for approaching trains and warn the work group in time to reach a place of safety

A look-out is posted to observe the line for approaching trains and give an agreed warning to the work group with sufficient time to reach safety.

Question 9: Which statement best describes the relationship between a lookout and the roadway worker in charge (RWIC)?

The lookout is directly responsible to and takes direction from the RWIC (Correct answer)
The lookout operates independently and reports only to the dispatcher
The lookout reports to the nearest signal maintainer
The lookout and RWIC have equal authority over on-track safety decisions

Correct answer: The lookout is directly responsible to and takes direction from the RWIC

The lookout works under the direct supervision of the RWIC and must follow the RWIC's instructions for positioning and warning procedures.

Question 10: At a highway-rail grade crossing worksite, a worker identifies the pedestrian crossing area as their position of safety. Why could this be problematic?

Pedestrian crossings can intersect with road traffic, creating a secondary hazard (Correct answer)
Only the flagperson may occupy crossing areas during active protection
Crossing surfaces create slip hazards in wet conditions
Grade crossings are always too close to the track to serve as a position of safety

Correct answer: Pedestrian crossings can intersect with road traffic, creating a secondary hazard

A highway-rail crossing area may expose a worker to road vehicle traffic while they wait for the train to pass, creating a secondary hazard that disqualifies it as a safe position.

Question 11: Which document or authority grants permission to occupy a track for emergency repair work?

The track foreman's written work order only
A Form B or equivalent track authority from the control center (Correct answer)
An email from the maintenance department
A verbal agreement between coworkers

Correct answer: A Form B or equivalent track authority from the control center

A Form B or equivalent track authority from the control center is required before any track occupation, including emergency repairs.

Question 12: A 'trap point' on a railway is designed primarily to:

Switch trains between two routes
Alert signallers to an unauthorized track entry
Slow down approaching trains automatically
Derail runaway vehicles to prevent them entering a main line (Correct answer)

Correct answer: Derail runaway vehicles to prevent them entering a main line

Trap points (also called catch points) are intentionally set to derail runaway or unauthorized vehicles before they can enter a main running line.

Question 13: What qualification must a person hold to act as a lookout on a PTS worksite?

A safety supervisor license
A valid PTS card and assessed lookout competence (Correct answer)
A general first aid certificate
A COSS certificate

Correct answer: A valid PTS card and assessed lookout competence

A person must hold a valid PTS card and be assessed as competent in lookout duties before they can act as a lookout.

Question 14: Which type of fire extinguisher is appropriate for a Class C (electrical) fire near track equipment?

Foam extinguisher
Water-based extinguisher
CO2 or dry chemical extinguisher rated for Class C fires (Correct answer)
Sand bucket only

Correct answer: CO2 or dry chemical extinguisher rated for Class C fires

CO2 or dry chemical extinguishers rated for Class C fires are used for electrical fires because water conducts electricity.

Question 15: When a track worker receives a radio call but cannot hear it clearly due to noise, what is the correct action?

Continue working until the radio clears up
Assume the message was not important
Acknowledge receipt and ask for the message to be repeated (Correct answer)
Ignore it and wait for a repeat

Correct answer: Acknowledge receipt and ask for the message to be repeated

Workers must acknowledge all radio calls and request clarification if the message is unclear to ensure no critical safety information is missed.

Question 16: If a roadway worker's radio battery fails during work and no backup is available, what is required?

Work must cease and the worker must clear the track until communications are restored (Correct answer)
The worker may continue if they are within sight of the lookout
Another worker can relay messages on their behalf
The worker can use their personal cell phone for dispatcher calls

Correct answer: Work must cease and the worker must clear the track until communications are restored

Reliable communication is a fundamental component of on-track safety; a dead radio removes a critical protective layer and requires work stoppage.

Question 17: What is the fundamental difference between working in a 'Red Zone' and a 'Green Zone'?

Red Zones are only for night work, while Green Zones are for daytime.
Red Zones are for emergency repairs only, while Green Zones are for planned maintenance.
In a Red Zone the line is open to traffic and requires a safe system of work, whereas in a Green Zone the line is blocked to all train movements. (Correct answer)
Green Zones have a Lookout appointed, while Red Zones rely on audible train warnings.

Correct answer: In a Red Zone the line is open to traffic and requires a safe system of work, whereas in a Green Zone the line is blocked to all train movements.

A 'Green Zone' is a work area where the line has been formally blocked, meaning no trains can enter the section. A 'Red Zone' is where work takes place while the line remains open to traffic, necessitating a robust safe system of work (such as a Lookout) to protect staff from moving trains.

Question 18: On the track layout, where is the ten-foot located?

Side on the left
in the middle (Correct answer)
side on the right

Correct answer: in the middle

In railway terminology, the 'ten-foot' refers to the clear space located in the middle, between two adjacent main running lines. This designated area is crucial for safety, providing a safe zone for workers to stand clear of trains operating on either track. It helps maintain a safe distance from moving rail traffic.

Question 19: What action must a worker take if they realize their established position of safety is inadequate just as a train begins to arrive?

Move immediately to a safer location if time permits, otherwise drop to the lowest possible profile away from the track (Correct answer)
Activate a personal alarm device to warn other workers and freeze in position
Signal the train engineer with both arms raised to indicate an emergency
Stay in place — moving at the last second is more dangerous than an imperfect position

Correct answer: Move immediately to a safer location if time permits, otherwise drop to the lowest possible profile away from the track

If time permits, any safer location should be sought immediately; if not, minimizing exposure by moving away and lowering profile reduces risk as much as possible in the remaining time.

Question 20: A worker hears the train warning signal and begins moving toward the position of safety. They arrive just as the train passes. What does this indicate?

The warning was given too late relative to required advance notice (Correct answer)
The lookout provided adequate warning time
The position of safety was too far from the work location
The worker's response time was acceptable under PTS rules

Correct answer: The warning was given too late relative to required advance notice

Lookouts must give workers sufficient advance warning so they can reach the position of safety well before the train arrives, not just as it passes.

Question 21: You are working near a track equipped with Overhead Line Equipment (OLE). What is the most critical and immediate hazard presented by OLE?

The risk of electrocution from the high-voltage lines. (Correct answer)
The possibility of the support structures collapsing.
Tripping over the bonding wires connected to the rails.
Noise from the equipment interfering with communication.

Correct answer: The risk of electrocution from the high-voltage lines.

Overhead Line Equipment (OLE) in the UK typically carries 25,000 volts of alternating current (25kV AC). Contact, or even coming too close with tools or equipment, can cause a fatal electric shock as the current can arc. This is the most severe and immediate life-threatening hazard associated with OLE.

Question 22: What hazard does 'cess vegetation' present to workers accessing the railway?

Cess vegetation is beneficial as it stabilises the ground for walking
It provides camouflage that makes workers invisible to train drivers
Vegetation only becomes a hazard during the growing season
Dense vegetation on the cess can hide trip hazards, obscure edges, conceal drainage ditches, and make footings uncertain — increasing the risk of falls toward the running line (Correct answer)

Correct answer: Dense vegetation on the cess can hide trip hazards, obscure edges, conceal drainage ditches, and make footings uncertain — increasing the risk of falls toward the running line

Dense cess vegetation hides trip hazards, drainage channels, and unstable ground — increasing the risk of falls that could put workers in danger near the running line.

Question 23: What action should a worker take if they are issued PPE that does not fit properly?

Modify the PPE themselves to improve fit
Use it anyway and adapt their work technique to compensate
Report the issue to their supervisor and request properly fitting PPE before beginning work (Correct answer)
Work the shift and report the issue afterward

Correct answer: Report the issue to their supervisor and request properly fitting PPE before beginning work

Ill-fitting PPE may not provide adequate protection; workers must report the issue and receive properly fitting equipment before starting work.

Question 24: On a curved track with restricted sightlines, how should the position of safety requirements change?

Workers may use the inside of the curve as a natural position of safety
The minimum distance from the rail can be reduced due to reduced train speed on curves
Workers need more time to reach safety, so the lookout must give warning earlier (Correct answer)
No change is required if a flagman is stationed at the curve

Correct answer: Workers need more time to reach safety, so the lookout must give warning earlier

Restricted sightlines on curves reduce the available warning time, requiring the lookout to be positioned further out and give warnings earlier so workers can clear in time.

Question 25: What is the maximum number of work parties a single COSS may simultaneously manage under a possession?

One work party at a time, unless specifically authorised otherwise in the safe system of work (Correct answer)
As many as needed on the same line
Two, if both are within radio contact
Three, provided they are within sight of each other

Correct answer: One work party at a time, unless specifically authorised otherwise in the safe system of work

A COSS should manage one work party at a time; managing additional parties requires explicit authorisation in the safe system of work documentation.

Question 26: What precaution must be taken when carrying long or large items (e.g. scaffold poles, rails, ladders) while accessing the railway cess?

Long items must be carried parallel to the running line (horizontally), never perpendicular, to prevent them fouling the running line if the carrier stumbles or loses grip (Correct answer)
Long items should be carried vertically to reduce their footprint
Long items must be carried by two workers walking side by side
No special precautions are needed for carrying long items in the cess

Correct answer: Long items must be carried parallel to the running line (horizontally), never perpendicular, to prevent them fouling the running line if the carrier stumbles or loses grip

Long items must be carried parallel to the line — if carried perpendicular and dropped or if the carrier falls, they could foul the running line and cause a derailment.

Question 27: What is the minimum ANSI visibility class required for workers on or adjacent to an active railroad track during daytime?

Class 3
Class 2 (Correct answer)
Class 1
No minimum class is specified for daytime

Correct answer: Class 2

ANSI Class 2 is the minimum required for workers near active railroad tracks during daytime, providing sufficient background material and retroreflective tape.

Question 28: Which of the following situations requires a new or amended job safety briefing?

A scheduled 10-minute break
A change in the protection method, work scope, or addition of new workers to the gang (Correct answer)
Switching from daytime to a slightly cloudier sky
A supervisor visiting the work site to observe

Correct answer: A change in the protection method, work scope, or addition of new workers to the gang

Any change in protection method, work scope, or gang composition requires a new briefing so all workers understand the updated safety conditions.

Question 29: What does it mean to be "on or near the line"?

In between the cess and the railroad boundary fence
In line or no more than three meters (10 feet) from a line (Correct answer)
On a line or two meters, or six feet, six inches, from a line
Outside the rail-bound border fence

Correct answer: In line or no more than three meters (10 feet) from a line

In Personal Track Safety (PTS) regulations, 'on or near the line' defines a critical hazardous zone. It means being either directly on the railway track or within a distance of no more than three meters (approximately 10 feet) from the nearest running rail. This area poses a significant risk of being struck by trains or moving railway plant, requiring strict safety protocols.

Question 30: How often must PPE be inspected and what should workers look for?

At the annual company safety review only
Before each use — checking for physical damage, wear, soiling, and that it still meets the required standard (Correct answer)
Only when it looks visibly damaged
Once a week by the site supervisor

Correct answer: Before each use — checking for physical damage, wear, soiling, and that it still meets the required standard

PPE must be inspected before each use for damage, wear, contamination, and continued compliance with the relevant standard. Defective PPE must be replaced immediately.

Question 31: What is the primary hazard when working inside a non-electrified railway tunnel?

Tunnel acoustics magnifying distant train noise, making warnings inaudible
Falling debris from the tunnel roof combined with very limited escape routes if a train approaches (Correct answer)
Risk of flooding from underground water tables beneath the invert
Excessive heat buildup caused by trains passing through in both directions

Correct answer: Falling debris from the tunnel roof combined with very limited escape routes if a train approaches

Tunnels present heightened risk because escape options are severely limited, noise echoes make train approach difficult to judge, and falling debris from aging structures is a constant danger.

Question 32: The required sighting distance for a lookout is determined by which factor?

The line speed of approaching trains (Correct answer)
The length of the worksite
The time of day
The number of workers on site

Correct answer: The line speed of approaching trains

The required sighting distance is based on line speed, ensuring sufficient time for all workers to reach safety before a train arrives.
