| Question | Answer |
| What is defined as 'on or near the line' | On a line or within 3m (10 feet) from the nearest line. On a platform is it within 1.25m (5 feet) |
| What is defined as 'lineside' | From the boundary fence to the point defined as 'on or near the line', and can be seen by the driver of an approaching train |
| What is a 'Running Line'? | Running lines are used by trains to go from place to place. Each running line has a name, speed limit and direction. Details are given in the Sectional Appendix. |

| List 6 requirements for going on or near the line | - have your Sentinel card with you - wear the necessary approved PPE and suitable workwear - know the speed and direction of approaching trains - know any hazards which might affect your safety - walk in a position of safety and face traffic, if possible - take extra care in junction areas |
| How long must you be in a position of safety before a train arrives? | 10 seconds |
| List 3 things you must do when a train is approaching | - stop what you are doing and go to the position of safety straight away - acknowledge the driver’s warning by raising one arm above your head - watch the train go past. |
| List 4 things you must do when crossing the line | - check there is a position of safety on the opposite site. - make sure there’s sufficient sighting distance and no trains are approaching - go straight across without stepping on rails or sleepers - take care near points as your foot could get trapped |
| Name 2 things to do when crossing a line with conductor rails | - find a gap or a place where protective guarding is provided - step over the running rail and conductor rail together |
| Name 7 things a COSS brief will contain | - the nature and location of the work - the access route and route to site - the limits of the site and how they are defined - the lines at the site, their speed limit, direction and whether they are open or blocked - the best means of contacting the Signaller and emergency sevices - hazards at the site such as electrification equipment - how you are protected from trains. |
| Describe a Safeguarded site of work | all lines are blocked |
| Describe a Fenced site of work | A fence is put up between the site of work and nearest open line. The distance between the fence and the open line depends on the type of fence and speed of trains. |
| Describe a Separated site of work | A space is provided between the site of work and nearest open line. The boundary of the work area depends on the size of the group and whether a Site Warden is appointed. |

| What is an ATWS | Automatic Track Warning System. Approaching trains are detected by the signaling system or equipment attached to the running rails The warning is given by trackside flashing lights and sirens and/or a personal warning device |
| What is a TOWS? | Train Operated Warning System Approaching trains are detected by the signalling system. The warning is given by trackside sirens |
| What warning methods can a Lookout use? (name 4) | Horn, whistle, touch or a flag |
| Describe a Lookout's badge | A Lookout wears a white badge or armlet with ‘LOOKOUT’ in red letters |
| Define 'Beyond' | The far side of a signal when looking in the normal direction of traffic |
| Define 'on the approach' | The near side of a signal or points when looking in the normal direction of traffic |
| What distance must you keep all metal objects away from signaling equipment? e.g an axle counter head | 30cm (1 foot) |
| Name 6 rules when using a road vehicle on or near the line | - COSS/SWL must be present and has given permission for the vehicle to be on or near the line - Not allow any part of the vehicle to come within 2m (6ft 6in) of any line - Switch on hazard warning lights - In darkness or poor visibility use dipped headlights - Turn the vehicle only at a suitable turning point and keep the back of the vehicle furthest from the line - Switch off all red lights when the vehicle is parked |
| Name 5 things you must do if you see something which could be a danger to trains | - Tell the person in charge, the signaller or Operations Control - connect a Track Circuit Operating Clip between the two running rails (except in fourth rail areas) - walk towards oncoming trains for 2km (1.25 miles) and place three detonators on the rail 20 metres (20 yards) apart - move at least 30 metres (30 yards) from the detonators - display a hand danger signal to approaching trains from a position of safety |
| What tools do you use to stop a train in daylight and darkness? | Daylight: Red flag, Red light or two hands raised to show danger Darkness: Red light |
| Describe the cess | The area alongside the railway |
| Describe the 4 foot | The space between the running rails of one line |
| Describe the 10-foot | A wider space between two of the lines in a area with three or more lines |
| Describe the 6 foot | The space between a pair of lines |
| What colour is a signal showing if it as 'at danger' | Red aspect |
| Describe the sign on an automatic signal | White rectangle with a horizontal black line through the middle |
| What is the difference between a main and distant signal? | A distant signal cannot show a red aspect |
| Describe the sign on an SPT | White square with diagonal black lines |
| Describe the sign on a lineside phone | White square with a black cross |
| Describe the sign on a level crossing phone | Yellow with a black phone icon |
| What does a red sign with 'Limited Clearance' on it tell you about the area beyond it? | There is no position of safety or refuges as the space between the track and nearest wall is narrow |
| What does a blue sign with 'No Refuges' on it tell you about the area beyond? | There are no positions of safety or refuges on this side of the railway, but there are on the other side |
| What are the minimum requirements for PPE when going on or near the line? | Safety helmet High vis trousers High vis upper body clothing Approved safety footwear |

| If you are attempting to protect a line and are part way through your walk of 2km to place detonators and you see a train approaching, what do you do? | Place three detonators immediately and display a hand danger signal. Stand 30 yards from the detonators |
| If you are attempting to protect a line and are part way through your walk of 2km to place detonators and you reach a tunnel, what do you do? | Place three detonators at the tunnel entrance. If the 2km distance is inside the tunnel, place three more detonators at the other entrance to the tunnel |
| If you are attempting to protect a line and are part way through your walk of 2km to place detonators and you reach a junction, what do you do? | Place three detonators on the line before the points. Decide which direction the next train is most likely to approach. Walk in that direction and place three detonators on the line 2km from the obstruction. Go back and do the same on the other line. |
| If an incident occurs on electrified lines who must be called first? | The Electrical Control Operator (ECO) so they can switch off the electricity in the area |
