Sample Personal Track Safety (PTS) Practice Questions

Try these sample questions to test your Personal Track Safety (PTS) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What distance from the nearest running rail defines the boundary of the 'Danger Zone' on Network Rail infrastructure?

A.Within 1.25 metres (4 feet) of the nearest rail (or within 2.0 metres on high-speed lines above 100mph)

B.Within 5.0 metres of any railway fence

C.Within 10.0 metres of any signal box

D.Within 0.5 metres of the rail web

Explanation: Under Network Rail PTS rules, you are in the Danger Zone if you are within 1.25 metres (4 feet) of a running rail (or within 2.0 metres if line speed exceeds 100 mph), unless standing in a designated Position of Safety.

2What is the minimum safe clearance distance required from live 25kV AC Overhead Line Equipment (OLE) under standard PTS rules?

A.2.75 metres (9 feet)

B.1.0 metre (3 feet)

C.0.5 metres (1.5 feet)

D.5.0 metres (16 feet)

Explanation: Under Network Rail PTS rules (Module AC), you must maintain a minimum distance of at least 2.75 metres (9 feet) from any live Overhead Line Equipment (OLE) or anything attached to it.

3What color of high-visibility clothing is MANDATORY for all personnel working on or near the line on Network Rail infrastructure?

A.High-visibility Orange (BS EN ISO 20471 / RIS-3279-TOM)

B.High-visibility Yellow

C.High-visibility Green

D.High-visibility Pink

Explanation: Network Rail standard RIS-3279-TOM mandates high-visibility ORANGE clothing for trackside work. Yellow high-vis is prohibited on track because it can be confused with yellow track hand signals or vegetation.

4Who is responsible for issuing a Safe System of Work (SSOW) briefing to track workers before going on or near the line?

A.The Controller of Site Safety (COSS) or Safe Work Leader (SWL)

B.The train driver

C.The nearest station ticket inspector

D.The recruitment agency administrator

Explanation: The COSS or SWL must conduct a thorough SSOW briefing before anyone accesses the track, explaining protection arrangements, hazards, positions of safety, and site boundaries.

5What safety device is used in an emergency to automatically trigger a red track circuit signal and stop approaching trains on track-circuited lines?

A.Track Circuit Operating Clip (TCOC)

B.Plastic cable tie

C.Wooden wedge

D.High-visibility armband

Explanation: A Track Circuit Operating Clip (TCOC) is clamped across both running rails in an emergency, short-circuiting the track circuit to place the protecting signal to RED.

6What is the minimum Position of Safety distance from a line where trains travel at speeds up to 100 mph?

A.1.25 metres (4 feet)

B.2.0 metres (6.5 feet)

C.0.5 metres (1.5 feet)

D.5.0 metres (16 feet)

Explanation: For line speeds up to 100 mph, a Position of Safety must be at least 1.25 metres (4 feet) from the nearest rail.

7What is the minimum Position of Safety distance from a line where trains travel at speeds between 101 mph and 125 mph?

A.2.0 metres (6.5 feet)

B.1.25 metres (4 feet)

C.0.75 metres (2.5 feet)

D.3.5 metres (11.5 feet)

Explanation: For high-speed lines between 101 mph and 125 mph, the Position of Safety must be at least 2.0 metres (6.5 feet) from the nearest rail.

8Under DC Conductor Rail electrification (750V 3rd rail), what is the minimum safe distance you should maintain from a live conductor rail unless stepping over it carefully?

A.Stay at least 300mm (1 foot) away from live conductor rails

B.Stay at least 2.75 metres away from conductor rails

C.Conductor rails carry no voltage and may be sat upon freely

D.Conductor rails are only live when trains pass

Explanation: You should avoid touching or stepping on 750V DC conductor rails and stay at least 300mm away unless approved protective insulation covers or isolations are in place.

9What action must you take if your Sentinel card is requested by an authorized Network Rail auditor or COSS on site?

A.Present your electronic or physical Sentinel card immediately for scanning and verification

B.Refuse to show the card unless paid a cash fee

C.Hand over a driver's licence instead

D.Inform the auditor that Sentinel cards are not required for track work

Explanation: You must carry your valid Sentinel card at all times when trackside and present it immediately upon request to prove medical, D&A, and PTS competence.

10What is meant by an 'Open Line'?

A.A line where train movements are operating normally and have not been stopped for work

B.A line that is under a total engineering block with no trains

C.A track that has been dismantled and removed

D.A pedestrian walkway inside a railway depot

Explanation: An 'Open Line' is a running line where train traffic is operational. Working on or near an open line requires approved protection arrangements (e.g. Lookout or Site Warden).
