Personal Track Safety (PTS) Exam — Questions and Answers
Question 1: What is the correct hierarchy of control when addressing a hazard identified in a risk assessment?
- Provide PPE first, then consider engineering controls
- Eliminate, substitute, engineer controls, administrative controls, PPE (Correct answer)
- Warn workers, provide PPE, then eliminate the hazard
- Train workers to accept the risk, then monitor
Correct answer: Eliminate, substitute, engineer controls, administrative controls, PPE
The hierarchy of control prioritizes eliminating the hazard first, then substitution, engineering controls, administrative controls, with PPE as the last resort.
Question 2: A COSS is about to start work but the planned protection method has become unavailable. What is the correct course of action?
- Implement the next available protection method and inform the group
- Proceed with reduced staff numbers to lower risk exposure
- Use a temporary lookout arrangement until the original method is restored
- Stop work, do not allow the group onto the line, and escalate to the PICOP (Correct answer)
Correct answer: Stop work, do not allow the group onto the line, and escalate to the PICOP
If the planned protection method is unavailable, the COSS must not allow anyone onto the line and must immediately escalate to the PICOP.
Question 3: What evidence should be preserved at the scene of a track accident before any investigation?
- Only the track worker's personal protective equipment
- Only photographic evidence — physical items should be cleared for safety
- Nothing — the priority is to resume track operations as quickly as possible
- Physical items, positions of equipment, and environmental conditions should all be preserved where safe to do so (Correct answer)
Correct answer: Physical items, positions of equipment, and environmental conditions should all be preserved where safe to do so
Preserving the scene, including positions of tools, equipment, and environmental factors, is critical for an accurate investigation — as long as this does not create additional risk.
Question 4: What is the mandatory minimum distance for a position of safety on a line where trains are permitted to travel at 125 mph?
- 3 metres (10 feet)
- 1.5 metres (5 feet)
- 1.25 metres (4 feet)
- 2 metres (6 feet 6 inches) (Correct answer)
Correct answer: 2 metres (6 feet 6 inches)
On lines where the speed limit is over 100 mph, the minimum distance for a position of safety is increased to 2 metres (6 feet 6 inches) to account for the increased aerodynamic effects of the passing train.
Question 5: What color is typically used to identify the overhead catenary wire on electrified rail systems in the US?
- Red insulated cable
- Yellow warning-coded sleeve
- Green earthed return wire
- Bare copper or aluminum wire (no color coding — position identifies it) (Correct answer)
Correct answer: Bare copper or aluminum wire (no color coding — position identifies it)
Overhead catenary wires are typically bare copper or aluminum and are identified by their position above the track, not by color coding.
Question 6: In lookout-protected working, where should the lookout be positioned?
- On the opposite track
- Behind the workers at all times
- At the center of the worksite
- At a position that achieves the required sighting distance in the direction of train travel (Correct answer)
Correct answer: At a position that achieves the required sighting distance in the direction of train travel
The lookout must be positioned to achieve the required sighting distance so trains can be spotted with enough time for workers to reach safety.
Question 7: When the COSS announces 'all out,' workers must:
- Move to the adjacent track
- Clear the track and reach a place of safety immediately (Correct answer)
- Acknowledge verbally and continue for up to 2 minutes
- Complete their current task first
Correct answer: Clear the track and reach a place of safety immediately
'All out' is an immediate instruction requiring every worker to clear the track and reach a place of safety without delay.
Question 8: Which of the following is a specific hazard presented by tamping machines or ballast regulators that does NOT apply to conventional passing trains?
- They are always electrified at 25kV
- They cannot be stopped once they begin moving
- They travel at speeds above 100 mph
- They discharge ballast, raise track, or eject material laterally during operation, which can injure nearby workers (Correct answer)
Correct answer: They discharge ballast, raise track, or eject material laterally during operation, which can injure nearby workers
Tamping machines lift and vibrate track, while ballast regulators and stoneblowers discharge or jet stone laterally at high velocity. These processes can project material considerable distances, posing crush, impact, and entanglement risks to workers nearby — hazards that are entirely absent when a conventional train simply passes.
Question 9: How does an IWA differ from a COSS-controlled safe system of work?
- IWA systems always require a full track possession
- An IWA requires more workers on site than a COSS system
- Under IWA there is no separate COSS or lookout — a single competent person manages their own protection (Correct answer)
- IWA can only be used on electrified lines
Correct answer: Under IWA there is no separate COSS or lookout — a single competent person manages their own protection
The fundamental difference is that an IWA is a single-person system with no COSS, lookout, or warning team. The individual must be competent and Sentinel-registered for IWA. A COSS-controlled system involves a COSS responsible for a team or work group, often with lookouts and a defined warning arrangement.
Question 10: A track gang supervisor notices that a minor cut injury was not reported because the worker 'didn't think it was a big deal.' What action should the supervisor take?
- Report the worker for intentional non-compliance without further discussion
- Only take action if the injury worsens and requires clinic treatment
- Document the injury retroactively and counsel the worker on reporting requirements (Correct answer)
- Accept the worker's judgment and move on
Correct answer: Document the injury retroactively and counsel the worker on reporting requirements
The supervisor must complete a retroactive injury report and coach the worker on the obligation to report all injuries, regardless of perceived severity.
Question 11: Under PTS rules, what must happen before removing blue flag protection from equipment?
- The supervisor must call the dispatcher for approval
- The nearest track foreman must sign a clearance form
- All workers who applied the protection must confirm they are clear (Correct answer)
- A two-hour waiting period must elapse
Correct answer: All workers who applied the protection must confirm they are clear
Blue flag protection may only be removed by or with the authorization of the same workers who applied it, once they are all clear of the equipment.
Question 12: Under FRA regulations, what is the employer's responsibility when a worker's PPE is damaged on the job?
- The employer must provide replacement PPE at no cost to the employee (Correct answer)
- Damaged PPE may be repaired by the worker and returned to service
- The worker is responsible for replacing their own damaged PPE at their own expense
- Replacement PPE is optional if the damage occurred during the final hour of the shift
Correct answer: The employer must provide replacement PPE at no cost to the employee
Under OSHA 29 CFR 1910.132 and FRA safety regulations, employers must provide and pay for required PPE; workers are not responsible for replacement costs.
Question 13: In reduced visibility conditions such as fog, what additional measure may be required beyond a standard lookout?
- Workers wear additional high-visibility vests
- Additional audible warnings and reduced line speeds may be required (Correct answer)
- Work continues normally with extra care
- Only experienced workers are permitted on site
Correct answer: Additional audible warnings and reduced line speeds may be required
In reduced visibility, additional safety measures such as enhanced audible warnings or imposed line speed restrictions may be required to maintain safety.
Question 14: After any on-track emergency event, workers are typically required to:
- Discuss the event only with their immediate team
- Take the remainder of the shift off automatically
- Complete a written incident report and, if required, submit to post-incident testing (Correct answer)
- Resume work immediately once the immediate danger has passed
Correct answer: Complete a written incident report and, if required, submit to post-incident testing
Railroad safety rules require a written incident report and may mandate post-incident drug and alcohol testing for all involved workers.
Question 15: What does 'COSS' stand for in UK Personal Track Safety?
- Coordinator of Safe Signals
- Controller of Stated Separation
- Chief Officer of Site Supervision
- Controller of Site Safety (Correct answer)
Correct answer: Controller of Site Safety
COSS stands for Controller of Site Safety, the person responsible for the safety of a work group on or near the track.
Question 16: Which term describes the sudden, violent movement of a rail caused by extreme temperature increase?
- Head check
- Sun kink (Correct answer)
- Rail creep
- Thermal fatigue
Correct answer: Sun kink
A sun kink (or thermal buckle) occurs when continuous welded rail expands rapidly in heat and buckles sideways without restraint.
Question 17: When a train approaches on an adjacent track while you are working, you should move to a position of safety that is at minimum how far from the nearest rail of any live track?
- At least 6 feet from the nearest rail
- At least 10 feet from the nearest rail
- At least 8 feet from the nearest rail
- At least 4 feet from the nearest rail (Correct answer)
Correct answer: At least 4 feet from the nearest rail
A position of safety requires being at least 4 feet (or the distance specified in your roadway worker protection procedures) from the nearest rail of any live track.
Question 18: What does 'possession' mean in the context of railway track work?
- Workers occupying the cess alongside an open line
- Ownership of railway infrastructure by contractors
- An arrangement where a section of line is taken out of use and handed to engineering teams (Correct answer)
- A competency held by track workers
Correct answer: An arrangement where a section of line is taken out of use and handed to engineering teams
A possession is a formal arrangement where a section of track is taken out of normal use and handed over to engineering teams for maintenance or renewal work.
Question 19: Why is it essential that the COSS counts all workers back out of a possession before handing it back?
- To confirm overtime hours for the shift
- To verify all tools have been collected
- To complete the payroll timesheet accurately
- To ensure no person remains on the line when train movements resume (Correct answer)
Correct answer: To ensure no person remains on the line when train movements resume
A headcount ensures every worker is accounted for and no one is left on the line before train movements are reinstated.
Question 20: Which color flag is used to indicate a danger/stop condition on railroad tracks?
- Blue
- Yellow
- Green
- Red (Correct answer)
Correct answer: Red
Red flags signal danger and require all trains and equipment to stop before that point.
Question 21: What is the primary role of a lookout in a PTS working environment?
- To direct train movements
- To operate track machinery
- To record train times
- To warn track workers of approaching trains (Correct answer)
Correct answer: To warn track workers of approaching trains
A lookout's primary role is to warn track workers of approaching trains so they can reach a position of safety in time.
Question 22: Why must safety footwear worn on track have ankle support as well as a steel toecap?
- Steel toecaps alone satisfy all track safety requirements
- To comply with fashion requirements on Network Rail sites
- Ankle support is only required for workers operating heavy equipment
- Because railway ballast is uneven and unstable, creating a high risk of ankle injury without adequate support (Correct answer)
Correct answer: Because railway ballast is uneven and unstable, creating a high risk of ankle injury without adequate support
Railway ballast is highly irregular and unstable underfoot. Ankle support in addition to a steel toecap significantly reduces the risk of ankle sprains and fractures from slips on ballast.
Question 23: Under what condition may a work gang re-enter a track after being involved in a close call or near-miss event?
- Immediately after confirming no injury occurred
- As soon as each individual worker feels ready to resume work
- After a mandatory 15-minute rest period
- Only after a job briefing review, identification of corrective actions, and supervisor authorization (Correct answer)
Correct answer: Only after a job briefing review, identification of corrective actions, and supervisor authorization
A near-miss must trigger a job briefing review to identify what went wrong and implement corrective actions before work resumes.
Question 24: What does the term 'PPE hierarchy' mean in a rail safety context?
- The order in which PPE items must be donned
- PPE ranked by cost from cheapest to most expensive
- PPE used as the last line of defense after engineering and administrative controls (Correct answer)
- The ranking of supervisors responsible for PPE inspection
Correct answer: PPE used as the last line of defense after engineering and administrative controls
In the hierarchy of controls, PPE is always the last resort after eliminating hazards, substitution, engineering controls, and administrative controls.
Question 25: What does the term 'adjacent line open' (ALO) mean for a track worker?
- Both tracks have been included in the same possession
- A relief track is available for emergency evacuation of workers
- Train movements are still occurring on a line next to where work is taking place (Correct answer)
- The adjacent line has been cleared of all obstructions
Correct answer: Train movements are still occurring on a line next to where work is taking place
Adjacent line open means that while work proceeds on one track, trains continue to operate on a neighbouring line, requiring heightened awareness from all workers.
Question 26: A lookout stationed on a curve signals danger. The correct egress direction for workers is:
- To the cess or designated place of safety on the correct side of the track (Correct answer)
- Toward the sound of the train to gauge distance
- Whichever direction each individual worker chooses
- Along the track in the direction the train is traveling
Correct answer: To the cess or designated place of safety on the correct side of the track
Workers must move to the pre-identified place of safety — typically the cess — on the appropriate side as briefed during the task briefing.
Question 27: A roadway worker is standing 4.5 feet from the nearest rail, watching a train pass. A large piece of timber stacked on a flatcar overhangs the car's side by 2 feet. Is the worker in danger?
- No — overhanging loads are always secured before departure and cannot shift
- Yes — but only if the timber is taller than the worker
- No — the 4.5-foot clearance is sufficient for all legal train loads
- Yes — the overhang extends the effective strike zone and could hit the worker (Correct answer)
Correct answer: Yes — the overhang extends the effective strike zone and could hit the worker
Loads that overhang beyond the normal car profile can extend into the fouling area and strike workers who are within the standard minimum clearance distance.
Question 28: A worker observes that a colleague has received an electrical shock from overhead equipment and is still in contact with it. What is the correct first response?
- Call for help and do not touch the victim until the circuit is confirmed de-energized (Correct answer)
- Throw water on the contact point to extinguish any fire
- Apply CPR immediately
- Grab the colleague and pull them free immediately
Correct answer: Call for help and do not touch the victim until the circuit is confirmed de-energized
Touching an electrocution victim in contact with live equipment will cause a second electrocution — the circuit must be confirmed de-energized before any contact.
Question 29: You are walking along the track and observe a sign showing a person in silhouette with a red line through it. What does this indicate?
- An authorised walking route is ahead.
- You are approaching a designated worksite.
- There is no position of safety on this side of the railway. (Correct answer)
- The line ahead is closed to all personnel.
Correct answer: There is no position of safety on this side of the railway.
This specific lineside sign is a limited clearance warning, which indicates that there is no position of safety on that side of the track for the length of the structure (like a bridge or tunnel) you are approaching.
Question 30: What is 'ballast' and what role does it play in railway track safety?
- A sand mixture used to improve rail adhesion in wet weather conditions
- The steel plate connecting the rail foot to the sleeper surface
- The crushed stone layer that supports sleepers, drains water, and distributes load (Correct answer)
- A weight placed on freight wagons to improve stability during transit
Correct answer: The crushed stone layer that supports sleepers, drains water, and distributes load
Ballast is the crushed stone layer beneath railway sleepers that provides drainage, distributes train loads, and holds the track in correct alignment.
Question 31: Which scenario correctly describes a worker properly using a position of safety?
- Worker steps to the opposite rail of the approaching train
- Worker stands in a drainage ditch 3 feet from the rail as a train passes
- Worker crouches beside the track to allow the train to pass overhead
- Worker moves behind a concrete barrier outside the track's fouling area before the train arrives (Correct answer)
Correct answer: Worker moves behind a concrete barrier outside the track's fouling area before the train arrives
A proper position of safety is outside the fouling area and protected by a physical barrier or sufficient distance before the train arrives.
Question 32: What does it mean when a flagman displays a red flag or red light to an approaching train?
- Stop immediately (Correct answer)
- Prepare to stop at next signal
- Proceed with caution at 10 mph
- Slow to restricted speed
Correct answer: Stop immediately
A red flag or red light displayed by a flagman is an absolute stop signal for an approaching train.
