Junction indicators are provided to show if a train is being signalled on a route to the left or right of the striaght route.
Normally located above the signal and will display a line of white lights when a proceed aspect is displayed.
At a junction with junction indicators will the straight ahead route have a junction indicator?
Generally No.
However, if the straight ahead route is not obvious, a junction indicator will be provided for the straight ahead route.
What is a route indicator?
A route indicator is provided at a signal and shows the route the trina is cleared on. They can show letters or numbers and can be with junction indicators. Also known as theatre box.

What is the purpose of Position Lights?
Position light signals allow a train to move into a section under caution, the line ahead may be occupied so the driver must drive at caution towards the next train, signal or buffer stop, and be prepared to stop short of any obstruction.
What are the two types of positon lights?
1. Associated Position Lights: Normally positioned with a main aspect signal, the normal apsect is unlit and this means obey main signal.
2. Ground Position Lights: Normally positioned at ground level independant of a main aspect. When proceeding on the authority of a main aspect all position lights in that section will show a proceed aspect.
What does a ground position light showing red/red or red/white mean?
Stop
[note: when proceeding on the auhority of a main aspect, any ground position light signals along the route between the main running signals will show a proceed aspect]
What does a ground position light showing yellow/white or yellow/yellow mean?
[Also known as a position light shunt signal]
Position light shunt signal: This is a STOP signal with regards to the main line to which it applies.
Other movements can pass this signal without it being cleared when a movement is being made towards the shunt neck or siding and not the running line.
What does a ground position light showing white/white at 45 degrees mean?
This authorises the driver to proceed at caution towards the next train, signal, or buffer stop and be prepared to stop short of any obstruction.
What does this Associated Position Light indicate?
- The driver is authorised to pass the main signal at danger,
- proceed at caution towards the next train, signal or buffer stop, and
- be prepared to stop short of any obstruction
Identitfy this sign set up and what it means?
Position Light with route indicator.
Displays letters and numbers and shows the route the trian is being signalled onto.
When a main apsect is not in use how will this be shown at the signal?
and
When a posiiton light is not in use how will this be shown at the signal?
Main Aspect: Bagged to prevent light seepage and a white/black cross over it
Position Light: Bagged to prevent light seepage

What does this sign mean?
GSMR not provided
This denotes the end to a GSMR serviced area, you will not be able to speak to the signaller on the GSMR.
What are these signs and what do they mean?
GSM-R signal phone number plate
GSM-R signal short code plate
At some locaiton the GSMR may not be able to route the dirver through to the correct siganller for that section so these signal phone number plates are put up to remind the dirver which number to use for the correct signaller for that section.
The short code plate is provided so the driver doesnt have the hardship of typing the whole 8 digit number, and can just use the quicker 4 digit number. [god bless the unions reducing the workload, nothing slips through the unions]
What are these phones all about?
Top ones are Signal Post Telephone, the five denotes how long a driver can wait at the signal before contacting the signaller. For exmaple, you stop at a red and see a train crossing ahead and you therefore know why your stopped you can wait until speaking to the signaller but if the signal is still red at 5 minutes you must ring him up.
Bottom one is a Line side Telephone: Provided to speak to the signaller
If these signs are on the signal post phone or lineside phone what does it mean?
These phone aree not in a positon of safety and can only be used to contact the signller when:

- When told the adjacent line has been blocked
What does it mean when the line side or signal post telephone have these signs on them?
These phone are not in apositon of safety however the driver stood in his own four foot is in apositon of saftery as a result of his or her own train.
Other railway staff can only use thes ephone when:
- In an emergency
- When told the adjacent line has been blocked
What does this sign mean?
Telephone not provided at this signal but the signaller knows your here through use of the track circuit.
When the same sign has a telephone number, it means the driver can use a mobile to contact the signaller on that number.

Green: Cleared to pass over leevl crossing under local control [this guy will never show a yellow flag to cross a level crossing becasue the driver could become confused and think he is clearing him to pass the intial signal at danger whihc he is not doing]
What is Track Circuit block Signalling
TCB signalling relies on continuous detection of trains through the block section. The track circuit gives the signaller continuous indication of a trains presence.
Signaller is free to admit a train into a block if it is clear of trains.
What is Permissive Working
It allows the signaller to allow one or more trains into a block at any one time.
Reasons for this might be to brings trains into a platform, assist a failed train, couple/uncouple, controlled emergency evacuation at a platform etc
True or False, most signalling systems work of the principle of one train in a block or signal section at any one time?
True
When you have been cleared for permissive working and proceeding towards a train at a stand how far should you stop short of that train?
2m [6ft 6inch]
[if you need to couple up with this train you would still stop two metres away before moving closer]
If you are permissive working and following a moving train, what three things do you need to do?
- Proceed at caution
- Leave enough room between your train and the one ahead to ensure if the train stops suddenly you have enough space and time to stop wihtout colliding
- if the train ahead is cleared through a signal you do not folllow, the signal will need to be reset to danger and then back to green if you are to follow.
When entering a station for permissive working what should be your maximum speed when reaching the start of the platform?
15 mph
If you pass a signal at danger SPAD, what should you do?
- Stop the train immediately
- Contact Signaller
- Answer his/her questions
- Do not move unitl instructed to do so
What is the DRA
Drivers Reminders Appliance
Its is a red button that when pulled out illuminates red and will not allow traction power to be taken, It should be used by the driver to remind the driver of a danger aspect ahead. For example, when passing a single yellow and then stopping at a station the driver should set it, this will remind the driver when setting off that he or she is at caution.
When should a driver set the DRA? [5 points]
clue: S S S E E R E
- Stopped at platform when signal at danger
- Stopping at any signal at danger [including stop boards]
- Stopped at station where no signal is provided but last signal was at caution
- Enter platform after being signalled past a signal at danger
- Enter a platform under a psotion of light auhtority
- Recieve a STOP on the GSM-R
- Entering or leaving the cab
What form do you use to report signal failures or irregularities
RT 3185
What is the AWS/TPWS fault code 5
Bell sounded when you expected the buzzer
[wrong side fault]
What is the AWS/TPWS fault code 7
No Indication when you should have recieved one
[wrong side fault]
What is the AWS/TPWS fault code 16
When the TPWS should have activated and it didnt.
{wrongside failure}
What is the AWS/TPWS fault code 17
The TPWS applied emergency brakes when it shouldnt have.
[Rightside Fault]
What are the four AWS/TPWS fault codes, 5, 7, 16 and 17
and if wrong side or right side faults and what does this mean?
Code 5: Bell instead of horn [WS]
Code 7: Nothing happened when it should have [WS]
Code 16: TPWS should have activated and it did not. [WS]
Code 17: TPWS applied brakes and it shouldnt have. [RS]
If these happen, STOP the train and contact the siganller. For right side faults the RT3185 form can be completed later and handed into your DM. For wrong side faults the form must be completed with the signaller there and then.
What signal faults need to reported to the signaller immediatly, stopping the train if required?
and
What signaling faults can be reported at the earliest possible time?
Wrong side immediately
right side at soonest opportunity
If the TPWS failed to initiate a brake demand when it should have done what fault code is this and is it wrongside or rightside fault?
Fault code 16, wrong side
When you are detained at a signal with no obvious reason for the delay what should you do?
Contact the signaller as soon as possible
When detained at a signal and there is an obvious reason for the delay how long can you wait until contacting the signaller [assuming no other instruction on signal post phone]
and
then how long to recontact them ]if not instructed otherwise].
If obvicous delay you can wait 2 minutes and then recontact every 5 minutes unless told otherwise.
[note, local rules may be different than these times so you will need to check]
If detained at a signal at danger, and there is no obvious reason for the delay, you need to contact the signaller as soon a possible. One the GSM-R where is the button you can use to let the signaller know you are there?
right hand side, SG button.
What is the SG button used for on the GSMR unit?
SG button: Lets the signaller know you are detained at a signal. He/she will usually send a wait message back.
What are the two most likely reasons to be signalled passed a signal at danger?
- Signal is faulty
- Signal cnanot be cleared due to fault in TC or level crossing equipment
- Permissive Working
When a signaller authorises you past a signal at danger what things do you need to have clear understanding of?
- What the fault is
- That it relates to you and your train
- The Signal Number
- How far the movement applies to
What is the procedure to pass a signal at danger?
- Ensure clear understanding with signaller [fault/you/signal No/far]
- Reset DRA
- Override TPWS
- Disregard AWS alarm
- Disregard SPAD board and AWS Horn
- Proceed with caution and check switches and points
When you have passed a signal at danger on authority how must you proceed to to the next signal or until told otherwise?
At caution and reduced speed
When you have passed a signal at danger on authority you must proceed at caution and reduced speed, however there are four exceptions to this, what are they?
- Single line working in right direction; LINESPEED
- Single line working; Wrong direction: 50 MPH
- Temporary Block Working: 50 MPH
- Single or bi Line with pilot man: LINESPEED
What is the process to pass a signal at danger on a hand signallers authority|?
- Handsignaler displays red flag and one detonator on line
- STOP AND WAIT for instructions
- Hand signaller will pass instructions from Signaller to you [make sure you understand them]
- Once understood HS will remove detonator and then display a yellow flag.
[only move your train when you have received information / understood it and received a yellow hand signal]
If you approach a signal at danger which is being operated by hand signaller who is there to authorise trains through at danger, and on the approach he displays a yellow flag to you what will you do?
STOP
The process when passing a signal at danger under a hand signallers authority is to stop and receive information relating to passing at danger and fully understand them. Only then should he should display a yellow hand signal and authorise you through.
[If you fall into this trap and let him send you through incorrectly this is a SPAD]
The only exception is when you have been in contact with the signaller already and he has relayed the information relevant to you and authorised you to follow the hand signaller signal.
When entering a TCB permissive working operation whereby the line ahead is occupied, what signal indication would you recieve associated with the mian aspect.
