Q

What is an unsignalled move?

A

A movement for which no signal has been cleared because:

Q

Before you operate a signal control to allow a train to proceed, what must you ensure? (TS2 Reg 3.1.1)

Q

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)

A
  • 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

Q

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)

A
  • 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

Q

When must you use reminder appliances on a signalling control? (TS1 Reg 3.5.1)

A
  • 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

Q

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)

A
  • 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

Q

When are you on or near the line? (G1 Reg 6)

A

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

Q

When are you lineside? (G1 Reg 6)

A
  • 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

Q

What is the definition of an automatic signal? (RS521 Reg 1.1)

A

A signal that is controlled by the passage of trains

17
Q

What is the definition of a controlled signal? (RS521 Reg 1.1)

A

A signal operated by the signaller

18
Q

A distant colour light signal can show which aspects? (RS521 Reg 1.1)

A
  • Green
  • Yellow
  • Double yellow

NB it cannot show red!

19
Q

What does the Sectional Appendix show?

A
  • Running lines

- Direction of travel and line speed

20
Q

What does a single yellow aspect indicate to a driver? (RS521 Reg 2.1)

A

Caution, be prepared to stop at the next signal

21
Q

Once a signal has been cleared, when can a signaller replace the signal to danger? (TS1 Reg 4.4)

A
  • 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
22
Q

What is the definition of a signal section? (TS2 Reg 1)

A

The line between two stop signals, whether or not these are within the control of the same signal box

23
Q

What is the definition of an overlap and what is the standard length? (TS2 Reg 1)

A

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

24
Q

What is the principle of track circuit block? (TS2 Reg 2)

A

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
25
Q

What does a flashing yellow aspect mean? (RS521 Reg 2.5)

A

A flashing yellow means facing points at a junction ahead are set for a diverging route with a lower permissible speed that that for the straight route

26
Q

When can you allow a train to approach a limit of shunt indicator that is defective? (TS11 Reg 11)

A
  • If the driver has been told about it

- The defective limit of shunt indicator is not needed to protect a conflicting movement

27
Q

What are the signallers immediate actions when they receive the emergency alarm?

A

Place the signals for the affected lines to danger

28
Q

A controlled signal has returned to danger for no apparent reason. What are your actions to ensure trains can run safely? (TS11 Reg 7.3)

A
  • Place a reminder device on the affected signal
  • Only allow a train to approach the signal when it is at danger
  • Clear the signal only when the train is at or nearly at at a stand at the signal
29
Q

What methods may a signaller use to caution drivers? (TS1 Reg 22)

A
  • Stop the train and advise the driver of the circumstances

- If permitted in the SBSI’s, you can use a berth-triggered GSM-R broadcast message

30
Q

Under what conditions are you permitted to caution moving trains using GSM-R berth-triggered broadcast messages? (RS523 Reg 8.4)

A
  • Reportable rail conditions
  • Animals on the line (except in tunnels)
