Personal Track Safety (PTS) Exam — Questions and Answers

Question 1: When must a PTS worker call 911 in addition to following internal railroad emergency protocols?

Only after obtaining permission from the supervisor
Never—only railroad control is contacted during track emergencies
When there is a threat to public safety, such as a grade crossing accident or fire (Correct answer)
Only when the incident involves a fatality

Correct answer: When there is a threat to public safety, such as a grade crossing accident or fire

Incidents that involve threats to public safety—such as grade crossing collisions or fires—require 911 notification alongside internal railroad protocols.

Question 2: In reduced visibility conditions such as fog, what additional measure may be required beyond a standard lookout?

Workers wear additional high-visibility vests
Work continues normally with extra care
Only experienced workers are permitted on site
Additional audible warnings and reduced line speeds may be required (Correct answer)

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 3: What is the purpose of a method statement in track work?

To schedule train movements around the worksite
To describe the step-by-step safe method for carrying out a task (Correct answer)
To list all workers on site by name
To record accidents and near misses

Correct answer: To describe the step-by-step safe method for carrying out a task

A method statement describes the step-by-step procedure for completing a task safely, ensuring all workers follow the same agreed safe method.

Question 4: Under PTS rules, what must happen before removing blue flag protection from equipment?

A two-hour waiting period must elapse
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)

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 5: If a worker hears the emergency alarm but cannot immediately see the hazard, what should they do?

Investigate the source of the alarm first
Notify the flagman and wait for confirmation
Continue working until they can confirm the hazard type
Immediately move to the designated place of safety (Correct answer)

Correct answer: Immediately move to the designated place of safety

Workers must immediately move to the designated place of safety without waiting to identify the specific hazard.

Question 6: Before a Roadway Worker in Charge (RWIC) can release a work crew from track authority, the RWIC must confirm that:

The train dispatcher has been notified
Workers have signed out on the job briefing form
The blue flag has been removed
All workers and equipment are clear of the track (Correct answer)

Correct answer: All workers and equipment are clear of the track

The RWIC must visually or verbally confirm all workers and equipment are clear before releasing track authority to allow train movement.

Question 7: Which of the following best describes a 'trap point' on a railway?

A derailing device installed to prevent unauthorized vehicles from entering an occupied section (Correct answer)
A type of crossing used at busy intersections
A point where animals frequently trespass onto the line
A signal that stops trains at a junction

Correct answer: A derailing device installed to prevent unauthorized vehicles from entering an occupied section

A trap point is a safety device designed to deliberately derail any runaway vehicle that passes it, protecting against unauthorized movements into occupied sections.

Question 8: A COSS must check the Sentinel card of every member of their workgroup. According to Sentinel scheme rules, when must this check be performed?

Every time an individual reports for duty with their workgroup for a shift. (Correct answer)
Only when instructed to do so by a Network Rail manager.
At the end of the shift when signing everyone out.
Only on the first day the person works with the group.

Correct answer: Every time an individual reports for duty with their workgroup for a shift.

Sentinel rules mandate that a competence and fitness-to-work check must be carried out by the COSS for every person, every time they join the workgroup for a shift. This ensures that everyone on site has the current and valid competencies required for the work.

Question 9: A dispatcher issues a track bulletin restricting speed in a work zone. Which party is responsible for informing train crews of this restriction?

The roadway worker nearest the track must flag each train
The maintenance-of-way supervisor must post signs at each end
The gang foreman must radio each train crew individually
The dispatcher communicates the track bulletin to train crews through established railroad operating procedures (Correct answer)

Correct answer: The dispatcher communicates the track bulletin to train crews through established railroad operating procedures

Dispatchers communicate track bulletins, slow orders, and other restrictions to train crews through the railroad's standard operating bulletin system.

Question 10: At what point during a 'withdrawal' should workers begin moving toward their position of safety?

As soon as the warning signal is given — without hesitation, without waiting to confirm the reason or retrieve tools (Correct answer)
Only when instructed by name by the COSS
When they can see the front of the approaching train
When the COSS confirms a train is definitely coming

Correct answer: As soon as the warning signal is given — without hesitation, without waiting to confirm the reason or retrieve tools

Workers must begin moving to their position of safety the instant the warning signal is given — any hesitation reduces the time available and can result in being struck.

Question 11: A lookout stationed on a curve has restricted sightlines. What is the appropriate response?

Add a second lookout positioned to cover the restricted sightline (Correct answer)
Request flagging protection from the nearest signal tower
Reduce the work crew to two people to speed up clearing
Station the lookout as close to the curve apex as possible

Correct answer: Add a second lookout positioned to cover the restricted sightline

When a single lookout cannot see far enough due to curves or obstructions, additional lookouts must be added to ensure full coverage.

Question 12: What is a 'line blockage' in railway operations?

A track defect requiring speed restrictions
A signal failure causing trains to stop
A formal arrangement preventing train movements on a specified line or section (Correct answer)
A physical barrier placed on the track

Correct answer: A formal arrangement preventing train movements on a specified line or section

A line blockage is a formal arrangement, authorised through the signaller, that prevents train movements on a specified section of track for a defined period.

Question 13: A workgroup's task involves using a road-rail vehicle with a hydraulic crane near OLE. The COSS has confirmed the OLE is live. What is the primary safety constraint for the vehicle operator?

The operator must wear electrically insulated gloves at all times.
The crane can only be operated for a maximum of 10 minutes at a time.
Ensure the vehicle's hazard lights are always flashing.
No part of the vehicle or its crane may come within 2.75 metres of the OLE. (Correct answer)

Correct answer: No part of the vehicle or its crane may come within 2.75 metres of the OLE.

The 2.75 metre (9 feet) exclusion zone applies to all personnel, tools, and equipment, including vehicles and plant. The operator must ensure that no part of the vehicle, including any extending parts like a crane, breaches this minimum safe distance from live OLE.

Question 14: What is the mandatory minimum distance for a position of safety on a line where trains are permitted to travel at 125 mph?

2 metres (6 feet 6 inches) (Correct answer)
1.5 metres (5 feet)
3 metres (10 feet)
1.25 metres (4 feet)

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 15: What must be confirmed before using a designated access point onto the railway?

The access point has been used by the team before on a previous shift
The access point is within 500 metres of the work site
Any gate or gap in the railway fence constitutes a valid access point
The access point is included in the site plan and risk assessment, the line protection is in place, and the COSS has authorised access (Correct answer)

Correct answer: The access point is included in the site plan and risk assessment, the line protection is in place, and the COSS has authorised access

Only designated, authorised access points may be used. The access must be included in the site plan and risk assessment, and the COSS must confirm protection is in place before access is given.

Question 16: What is 'ballast' in railway engineering?

The concrete foundation under sleepers
The crushed stone layer supporting the sleepers and distributing load (Correct answer)
The drainage channel alongside the track
The metal fastening holding rails to sleepers

Correct answer: The crushed stone layer supporting the sleepers and distributing load

Ballast is the layer of crushed angular stone placed under and around sleepers to distribute the load of trains, drain water, and maintain track geometry.

Question 17: How does working on an adjacent line while trains run on a neighbouring line affect the position of safety requirements?

Workers on the blocked line do not need to concern themselves with the adjacent running line
The line blockage on one line automatically protects workers from adjacent running lines
Workers on a blocked line must still maintain a position of safety clear of any adjacent running lines when trains pass on those lines (Correct answer)
Workers may approach to within 1 metre of an adjacent running line if they can see approaching trains

Correct answer: Workers on a blocked line must still maintain a position of safety clear of any adjacent running lines when trains pass on those lines

A line blockage on one line does not protect workers from adjacent running lines. Workers must move to a position of safety clear of all running lines when trains pass on adjacent lines.

Question 18: Out of five alternatives, which two constitute a safe system?

Equipment alert (Correct answer)
Protected (Correct answer)
Accurate Uniform

Correct answer: Equipment alert

A safe system of work in a railway environment relies on multiple protective measures. Being 'protected' means ensuring workers are shielded from hazards, for example, by designated safe zones or line blockages. 'Equipment alert' implies that all equipment is in safe working order and that workers are vigilant about their surroundings and any equipment-related risks, contributing to overall safety.

Question 19: On a high-speed line (125 mph), how does the required warning distance for lookout protected working compare to a slow line (25 mph)?

The warning distance is the same regardless of line speed
Lookout protected working is not permitted on lines above 100 mph
High-speed lines require only a slightly longer warning distance
The warning distance on a 125 mph line is approximately five times greater than on a 25 mph line, requiring the look-out to be positioned much further away (Correct answer)

Correct answer: The warning distance on a 125 mph line is approximately five times greater than on a 25 mph line, requiring the look-out to be positioned much further away

Warning distance is directly proportional to line speed — a train at 125 mph covers ground five times faster than at 25 mph, so the look-out must be positioned five times further away to give the same warning time.

Question 20: What must a COSS do when planning work that may bring workers or equipment close to the 750V DC third rail?

Work is safe if tools are wooden
Obtain a third rail isolation for the relevant section, confirmed by a qualified Traction Electrical Engineer, before allowing any work where accidental contact is possible (Correct answer)
Mark the third rail with warning cones and proceed
Train workers to jump over the third rail quickly

Correct answer: Obtain a third rail isolation for the relevant section, confirmed by a qualified Traction Electrical Engineer, before allowing any work where accidental contact is possible

A third rail isolation must be obtained from a qualified Traction Electrical Engineer before any work is planned that could result in accidental contact with the 750V DC third rail.

Question 21: What is the requirement for safety footwear on railway sites in terms of the EN ISO 20345 standard?

Any work boot with a steel toecap meets railway requirements regardless of standard
Safety footwear standards only apply to workers operating machinery
Safety footwear must be S1 rated only
Safety footwear must be at least S3 rated (steel toecap, midsole puncture protection, water-resistant upper, and anti-slip sole) or as specified in the site risk assessment (Correct answer)

Correct answer: Safety footwear must be at least S3 rated (steel toecap, midsole puncture protection, water-resistant upper, and anti-slip sole) or as specified in the site risk assessment

Railway site standards typically require S3-rated safety footwear under EN ISO 20345, providing steel toecap, midsole protection, water resistance, and anti-slip soles suitable for ballast and wet conditions.

Question 22: What is the significance of a 'positive stop' requirement in PTS?

All workers must stop walking when a train passes
Workers must physically plant both feet before giving signals
Equipment must be capable of stopping before a specific point, not just slowing down (Correct answer)
Trains must halt at every work zone regardless of protection in place

Correct answer: Equipment must be capable of stopping before a specific point, not just slowing down

A positive stop requirement means equipment must be able to stop before a defined point, ensuring a definitive margin of safety rather than just reduced speed.

Question 23: Who has the authority to remove a blue flag that has been placed to protect roadway workers?

The train dispatcher
The locomotive engineer upon request
Only the workers who placed it (Correct answer)
Any supervisor at the work site

Correct answer: Only the workers who placed it

FRA regulations require that only the roadway worker or work group who placed a blue flag may remove it, ensuring workers cannot be endangered by unauthorized removal.

Question 24: When exiting the track in an emergency, workers should move to the nearest:

Place of safety such as a refuge area or clear of the gauge (Correct answer)
Station platform regardless of distance
Signal box
Adjacent track

Correct answer: Place of safety such as a refuge area or clear of the gauge

In an emergency, workers must immediately move to a designated place of safety such as a refuge area or a position clear of the track gauge.

Question 25: What is the legal basis for employers providing PPE to track workers?

The Personal Protective Equipment at Work Regulations 1992 (as amended), which require employers to provide suitable PPE free of charge where risks cannot be adequately controlled by other means (Correct answer)
Network Rail's internal guidance documents only
The Construction Design and Management Regulations 2015
The Railways Act 1993

Correct answer: The Personal Protective Equipment at Work Regulations 1992 (as amended), which require employers to provide suitable PPE free of charge where risks cannot be adequately controlled by other means

The Personal Protective Equipment at Work Regulations 1992 (as amended in 2022) require employers to provide suitable, correctly fitted PPE free of charge where risks cannot be sufficiently reduced by other means.

Question 26: A Sentinel cardholder notices that a colleague appears unwell before a trackside shift. What is the correct course of action?

Allow the colleague to start work and monitor them throughout the shift
Report the concern to the supervisor so a fitness assessment can be carried out before the colleague accesses the line (Correct answer)
Say nothing to avoid conflict and let the colleague decide
Contact Sentinel directly without telling the supervisor

Correct answer: Report the concern to the supervisor so a fitness assessment can be carried out before the colleague accesses the line

Raising a fitness concern with the supervisor before the shift starts ensures no unfit worker accesses the line, protecting both the individual and the team.

Question 27: What is a 'cess' in the context of railway track infrastructure?

The space between two running rails
The ballast layer beneath the sleepers
The drainage channel or walkway area running alongside the track (Correct answer)
A type of signal control system

Correct answer: The drainage channel or walkway area running alongside the track

The cess is the area alongside the railway track, including the drainage ditch and ground-level walkway where workers travel.

Question 28: A worker's hi-vis vest is torn and missing several inches of retroreflective tape. What is the correct action?

Continue work since the remaining tape is sufficient
Remove the vest from service and obtain a compliant replacement (Correct answer)
Repair the tape with electrical tape and continue
Wear the vest inside-out to avoid inspection issues

Correct answer: Remove the vest from service and obtain a compliant replacement

Damaged or non-compliant hi-vis garments must be removed from service immediately and replaced with compliant PPE.

Question 29: Who is responsible for appointing a lookout for a track work activity?

The Network Rail control room
The train driver
The lookout themselves
The COSS or person in charge of the work (Correct answer)

Correct answer: The COSS or person in charge of the work

The COSS (Controller of Site Safety) or person in charge is responsible for appointing a qualified and competent lookout.

Question 30: What does 'OLE' stand for in railway safety terminology?

Onboard Locomotive Electronics
Overhead Line Equipment (Correct answer)
Outer Limit Exclusion zone
Outgoing Line Entry signal

Correct answer: Overhead Line Equipment

OLE stands for Overhead Line Equipment, referring to the electrified wires suspended above the track that provide traction current to electric trains.

Question 31: A PTS worker's personal protective equipment (PPE) is damaged during an emergency. When may they continue working?

If a supervisor verbally approves the damaged PPE for the remainder of the shift
Only after replacement PPE meeting the required standard has been obtained (Correct answer)
Immediately, since the emergency overrides PPE requirements
After the shift ends and they have filed a report

Correct answer: Only after replacement PPE meeting the required standard has been obtained

Work may not resume until replacement PPE meeting the required standard is obtained; damaged PPE provides insufficient protection.

Question 32: What is meant by a 'defined' position of safety on a job briefing?

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

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.
