General Flashcards
What type of train may ask to stop in section? (TW1 Reg 40)
- MPV (Rail Grinder or Mobile Maintenance Team)
- Officers’ Special
- Freight train that is required to make an unscheduled call at an intermediate siding
- An engineering train that is to stop at a FTAP before working in a possession or PZ
When can you clear a calling on signal? (TS2 Reg 4.8)
When the train has stopped or has nearly stopped at the signal
What are the types of stop signals? (RS521 Reg 1.1)
- Stop signal
- Buffer stop indications
- Position-light signal
- Possession limit board
- Limit of Shunt signals or indicators
- Shunting signals
- Stop boards
- Work-site marker boards
You must always use the main aspect or indication when there is an associated subsidiary or position-light signal, except when? (TS1 Reg 4.9)
- Permissive working
- Shunting
- SLW or working by pilotman
- Detaching / attaching
- A failure of equipment means that the main aspect or indication cannot be displayed
What is a signalled move?
A movement where a signal has been cleared for the train to proceed
What is an unsignalled move?
A movement for which no signal has been cleared because:
- the signal is to be passed at danger
or
- no signal is provided
Before you operate a signal control to allow a train to proceed, what must you ensure? (TS2 Reg 3.1.1)
- No other movement that may conflict is to be made first
- The route is set or is free to be set by the interlocking
- If necessary, you have been given a release by another signaller
Before you allow a movement to occupy a track circuit which would change the aspect shown at any signal, what must you do? (TS2 Reg 3.1.2)
- You must place or keep the necessary signals at danger to protect the movement
- If another signaller controls that signal, you must not allow the movement to take place until that signaller tells you the signal is at danger
When can you allow the line within the overlap of a signal to be obstructed or occupied by an unsignalled movement? (TS2 Reg 3.1.3)
- Any approaching train has been stopped at that signal
or
- If no train is approaching that signal, the previous controlled signal has been placed to danger to protect the obstruction or movement
When must you use reminder appliances on a signalling control? (TS1 Reg 3.5.1)
- When the normal passage of trains (or certain trains) is stopped
- When trains can pass only after the driver has been told to proceed at caution in connection with an incident, failure or unusual occurrence
- When any signal, route setting position, or level crossing equipment is disconnected or defective
- When the signal is protecting a train or vehicles detained or left on a running line where track circuits are not operated
When can you remove reminder appliances? (TS1 Reg 3.5.5)
- If the line is clear and normal working is resumed
- If you need to signal a train for a route that is not affected, or for a movement to proceed after the driver has been told to proceed at caution
What is the definition of a traction unit? (Glossary)
- Locomotive
- Multiple units
- Self propelled vehicle
- Road-rail vehicle operating in rail mode
When can you clear a signal for a diverging route when you don’t have approach release? When does this not apply? (TS1 Reg 4.11.1)
- The train is close to the signal
- The speed of the train has been suitably reduced
- This is not required if published in the working timetable or the supplement to the working timetable
When are you on or near the line? (G1 Reg 6)
You are on or near the line if you are:
- On the line itself
- Within 3m (10ft) of a line and there is no permanent fence or structure between you and the line
You are not on or near the line if you are on a station platform unless you are carrying out engineering or technical work within 1.25m (4ft) of the platform edge
You are not on or near the line if you are crossing the line at a level crossing
When are you lineside? (G1 Reg 6)
- You are between the railway boundary fence and the area called on or near the line
And
- You can be seen by the driver of an approaching train
You are not lineside if you are on a station platform
What is the definition of an automatic signal? (RS521 Reg 1.1)
A signal that is controlled by the passage of trains
What is the definition of a controlled signal? (RS521 Reg 1.1)
A signal operated by the signaller
A distant colour light signal can show which aspects? (RS521 Reg 1.1)
- Green
- Yellow
- Double yellow
NB it cannot show red!
What does the Sectional Appendix show?
- Running lines
- Direction of travel and line speed
What does a single yellow aspect indicate to a driver? (RS521 Reg 2.1)
Caution, be prepared to stop at the next signal
Once a signal has been cleared, when can a signaller replace the signal to danger? (TS1 Reg 4.4)
- When it won’t cause the driver to see an irregular sequence
- When you have made sure that the driver is aware that you are going to do so
- When you have made sure that the train does not have a driver
- In an emergency
What is the definition of a signal section? (TS2 Reg 1)
The line between two stop signals, whether or not these are within the control of the same signal box
What is the definition of an overlap and what is the standard length? (TS2 Reg 1)
The distance beyond a stop signal up to which the line must be clear before the previous stop signal can show a proceed aspect
183m
What is the principle of track circuit block? (TS2 Reg 2)
The track circuit block system allows a signal to show a proceed aspect when:
- All track circuits up to and including the overlap of the next stop signal are clear
- All necessary points within the route are detected in the correct position for a train to pass safely
