Train signalled towards a wrong route
If your train has been signalled towards a wrong route, what must you do?
You must:
- Stop the train as soon as it is possible to do so safely
- Tell the signaller.
Signals that control the exit from sidings
If the signal applies to more than one siding and there are other trains standing in these sidings, what must you not do when the signal clears?
You must not move forward and foul any of these sidings when the signal clears, until the person in charge of movements gives you permission to do so.
Signal not showing or not showing correctly.
If a signal is not showing or not showing correctly, how must you treat:
- A stop signal
- A distant signal
- A position-light signal, subsidiary signal or shunting signal
You must treat these signals as:
- A stop signal as being at danger.
- A distant signal as being at caution.
- A position-light signal, subsidiary signal or shunting signal as being at normal.
Train stopped before the whole train has passed a signal that is showing ‘proceed’
If you have stopped the train before the whole train has passed a signal that is showing ‘proceed’. How would you proceed?
You may act on the aspect or indication that was being displayed when you passed the signal. This applies unless you are instructed that the train is not to proceed.
Passenger train at a position-light or semaphore shunting signal
Can you proceed with a passenger train on the authority of:
- A semaphore shunting signal.
- A position-light signal.
No:
You must not proceed with a passenger train on the authority of:
- A semaphore shunting signal.
- A position-light signal.
Route indication not shown
If a position-light or subsidiary signal is cleared but the normal route indication is not shown, how would you proceed?
You must:
- Make sure the movement is made at caution.
- Be prepared to stop before you reach any obstruction.
Returning to the approach side of a signal
When can you proceed on your journey after carrying out a shunting movement on the authority of a position-light signal, or a shunt-ahead signal?
You must not proceed on your journey until:
- The movement has returned to the approach side of a signal
- The signal displays the appropriate proceed aspect or indication for the movement.
Train standing beyond a signal (Shunting)
When the signal can be cleared for the reverse movement, part of your train is standing beyond the signal controlling the movement. when can you proceed?
When the signal has cleared.
If any part of your train is standing beyond the signal controlling the movement, you must not start the movement until the signal is cleared. If you cannot see the signal, you must ask the guard, shunter or driver at the other end of the movement to tell you when the signal is cleared.
Train standing beyond a signal (Shunting)
<strong>When the signal cannot be cleared for the reverse movement</strong>
What must you do if the signal cannot be cleared?
If the signal cannot be cleared, you must:
- Find out whether a movement can be made which will allow the whole train to be positioned on the approach side of the signal.
- If necessary ask the signaller for permission to do this.
If it is not possible for the train to return to the approach side of the signal,
what must you do?
You must ask the signaller for permission to proceed beyond the signal in the direction to which it applies.
If AWS brings your train to a stand by applying the breaks.
What must you do?
If you do not immediately cancel the AWS warning indication, the brakes will be automatically applied. In this case you must:
- Make sure the train comes to a stand
- Tell the signaller what has happened. If you are both sure that it was not TPWS on track equipment that caused the brake application, the train can proceed normally.
AWS warning when there is no AWS track equipment
If you receive an AWS warning indication and you are certain that the train has not passed over any AWS on track equipment what are your actions?
You must:
- Proceed normally
- Report this to the signaller at the earliest opportunity.
TPWS operation other than approaching buffer stops
If an automatic brake application is initiated as a result of the operation of TPWS, what must you do?
You must:
- Acknowledge the TPWS brake demand
- Make sure the train comes to a stand
- Tell the signaller what has happened
- Carry out the instructions you are given by the signaller
- Not make any further movement of the train until instructed.
TPWS operation when approaching buffer stops
If an automatic brake application is initiated as a result of the operation of TPWS when approaching buffer stops, what must you do?
You must:
- Acknowledge the TPWS brake demand.
- After the train has come to a stand, move forward to the normal stopping point if it is safe to do so.
- Tell the signaller what has happened.
- Carry out the instructions you are given by the signaller.
Reporting signalling failures and irregularities
Name at least 3 signalling failures or irregularity that must be reported immediately.
You must tell the signaller immediately, stopping the train specially if necessary, if you become aware of a signalling failure or irregularity on any line. This may include:
- The failure in the working of a signal
- An irregularity in the working of a signal
- An irregular aspect sequence
- A missing block marker or no signal shown when there should be one
- The aspect of a colour light signal not being distinct or obvious
- A semaphore signal not showing correctly
- A white light showing instead of a red, yellow or green.
- A signal or associated indicator difficult to see because of sunlight, streetlights or reflections.
- A signal difficult to see because of trees, foliage or other obstructions.
When must you report any signal failures or irregularities with the following signals:
- A position-light signal.
- A subsidiary signal.
- A shunting signal.
You must tell the signaller at the first opportunity without causing delay.
When must you report any of the following if they are missing, unlit when it should be lit or become difficult to see?
- A limit of shunt signal or indicator.
- A shunt entry board.
- A ‘start of cab signalling’ board.
- An ‘end of cab signalling’ board.
- A stop board.
- Any other lineside board or sign.
You must tell the signaller at the first opportunity. You do not need to stop the train specially to do this.
Reporting a signal / AWS / ERTMS/TPWS failure or irregularity
What form must be filled out when you have a Signal, AWS, ERTMS or TPWS failure or irregularity?
You must complete form RT3185 with all the required details. Completed RT3185 forms must be handed in as shown in your company instructions.
Reporting a signal / AWS / ERTMS/TPWS failure or irregularity
When do you not need to immediately complete a RT3185 form?
If the Signaller:
- Can tell you the fault or irregularity is clearly a right-side failure.
- Can explain why it is a right-side failure and can confirm the circumstances of the failure.
Reporting a signal / AWS / ERTMS/TPWS failure or irregularity
When do you not need to immediately complete a RT3185 form?
If the Signaller:
- Can tell you the fault or irregularity is clearly a right-side failure.
- Can explain why it is a right-side failure and can confirm the circumstances of the failure. You must then complete RT3185 at the first convenient opportunity.
Reporting AWS faults
When must you immediately tell the signaller regarding AWS faults?
You must immediately tell the signaller, stopping the train specially necessary, if:
- You receive an AWS clear indication when a warning indication should have been received (fault code 5).
- You do not receive any AWS indication when a warning indication should have been received (fault code 7).
Reporting AWS faults
What is AWS Fault Code 5?
Fault Code 5 is when you receive an AWS clear indication when a warning indication should have been received.
Reporting AWS faults
What is AWS Fault Code 7?
Fault code 7 is when you do not receive any AWS indication when a warning indication should have been received.
Reporting AWS faults
Other AWS faults where the failure is to give a clear indication.
when must these be reported?
These must be reported to the signaller at the first convenient opportunity.
