PTS PTS - Personal Track Safety Railway Hazards and Terminology 2 — Questions and Answers

Question 1: What is the term for the minimum distance that track workers must keep from a running line when a train is approaching?

Clearance distance
Position of safety (Correct answer)
Cess distance
Warning distance

Correct answer: Position of safety

A position of safety is the distance and location where a track worker is clear of all moving trains and other hazards on the line.

A position of safety is a specific location where a worker is clear of all train movements on adjacent lines and other hazards. It must be at least 2 metres from the nearest rail of any running line, or inside a designated refuge. Workers must achieve their position of safety before a train arrives, not as it passes. This is a fundamental PTS requirement covered extensively in the Network Rail Rule Book.

Question 2: What does the term 'cess' refer to on a railway?

The railway ballast layer
The area of ground beside the track outside the rails (Correct answer)
The signalling control room
The tunnel drainage channel

Correct answer: The area of ground beside the track outside the rails

The cess is the strip of ground running alongside the railway track, outside the rails, which workers use for access and egress.

The cess is the strip of land immediately alongside the railway formation, outside the running rails. It is used by track workers as an access route and place of safety. The cess may be uneven, slippery, or obstructed, so workers must remain vigilant. On some lines the cess is very narrow or non-existent, which affects the safe systems of work that can be used. Understanding cess conditions is essential for planning safe working.

Question 3: What is a 'line blockage' in railway operations?

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

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.

A line blockage is a formal protection arrangement that prevents all train movements on a specified line or section of track. It must be obtained from and confirmed by the signaller before work begins. The COSS (Controller of Site Safety) is responsible for obtaining and managing the blockage. Line blockages are a primary means of protecting workers and are governed by the Network Rail Rule Book Module T2. The blockage must be formally surrendered before trains can resume.

Question 4: What does 'fouling point' mean in railway terminology?

The point where debris accumulates on the track
The location where vehicles on converging lines would come into contact (Correct answer)
A contaminated section of ballast
The point where a signal aspect changes

Correct answer: The location where vehicles on converging lines would come into contact

A fouling point is the location at a set of points (switches) where vehicles on converging lines would first come into contact with each other.

A fouling point is the nearest location to a set of points at which a vehicle on one line would foul (strike) a vehicle on the converging line. Track workers must not stand between the fouling point and the points themselves unless the lines are both blocked. Fouling points are marked or calculated as part of site safety planning. Understanding fouling points is critical when working in station throats, sidings, or complex track layouts.

Question 5: What is the purpose of a 'look-out' in a Lookout Protected Working system?

To observe track geometry defects
To watch for approaching trains and give timely warning to workers (Correct answer)
To record train movements in the working area
To liaise with the signaller about line occupations

Correct answer: To watch for approaching trains and give timely warning to workers

A look-out watches for approaching trains and gives a timely warning signal to allow all workers to reach a position of safety before the train arrives.

A look-out is a competent person appointed to observe for approaching trains and give an audible warning in sufficient time for all workers to reach a position of safety before the train arrives. The look-out must be positioned where they can see approaching trains at an adequate distance (at least the warning time distance for the permitted speed). They must not carry out any other duties while acting as look-out. The look-out system is governed by Module T3 of the Network Rail Rule Book.

Question 6: What does 'possession' mean in the context of railway track work?

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)
Workers occupying the cess alongside an open line
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.

A possession is a formal arrangement, planned and authorised in advance, where a section of track is taken out of use and handed to an engineering possession manager for maintenance, renewal, or inspection work. Possessions are managed under Module T3 of the Network Rail Rule Book. Within a possession, the Engineering Supervisor (ES) controls the track, and COSS teams work under the ES's authority. Possessions are planned weeks in advance and must be set up and surrendered in a strictly defined sequence.
