3. Exceptions to pass fixed signals at ABS and ATC systems Flashcards
Under the ABS system, what must you do if you are detained at a Home Signal at Stop? (3)
- Sound one long whistle
- Contact the controlling signaller
(Provide TDN, Signal Post No., Position of Train) - Provide a PA announcement
Under the ABS system, if you contact a Controlling Signaller when detained at a Home Signal, what information must the Controlling Signaller provide? (3)
- Expected duration of delay
- The reason for delay
- If Blocking Facilities have been applied
Under the ABS, when detained at a Home Signal when should the driver contact the Train Controller at Metrol? (3)
- If Controlling Signaller can’t be contacted OR
- If driver is not satisfied with response of Controlling Signaller OR
- Signaller has informed the delay will exceed five minutes
Under ABS, what must a driver do if they encounter an automatic signal at stop? (3)
- Stop train prior to signal
- Not pass signal if line ahead is known/seen to be obstructed
- Assume track ahead is occupied, obstructed or damaged
Under ABS, what train-related safety issues must a driver consider before passing an automatic signal at stop? (4)
- Braking ability of the train when considered against the gradient of track
- Defective or isolated equipment
- Bad weather conditions
- Restricted visibility (e.g. graffiti on windscreen, sunglare etc)
What phone call must a driver make before passing an automatic signal at stop and what details must they provide?
- They must call the Rule 1 Section 3 recorded message number and provide their name, motor number, signal number and TDN
Briefly describe the process a driver must undertake when performing Rule 1 Section 3 at an Automatic Signal:
- Stop at Red/defective aspect
- Assume track ahead is occupied, obstructed or defective
- If train has safe operation faults, driver can refuse to enter track section and call Train Controller at Metrol
- Leave message with Recorded Radio number and give name, signal no, motor no and TDN
- Make a PA and sound long whistle
- Proceed at extreme caution until whole train has cleared the next fixed signal
- Stop the train if another train is seen to ascertain direction
- Submit incident report
Extreme Caution is defined as:
- Being able to stop the train in half the distance that can be seen ahead
- Not exceeding 25km/h or posted track speed if lesser, until the whole train has passed the next fixed signal
- Always being prepared to find the section ahead occupied, obstructed or damaged
If there has been an equipment failure and a level crossing mechanism has not been triggered (boom arms still raised), how might a driver apply Rule 1 Section 3?
Driver is to move with extreme caution past the signal at stop until the boom barriers/flashing lights are triggered by circuitry.
Train must not enter level crossing until equipment is operating or until railway personnel are protecting the crossing.

Dictated from non-recorded remote controlled signal boxes
It will be read to the driver over the signal post telephone – driver must complete and retain.
What locations will a driver be transmitted a Signallers Caution Order?
What is the process?
Transmitted from recorded locations.
Can be transmitted via DTRS or Signal Post Phone. Driver does not need to write details, but must keep record of signallers name.
What are the three steps a driver must perform when passing a Home Signal at Stop where there is no Calling-on/Low-Speed Caution signal?
- Stop before signal
- Receive verbal instruction and/or green hand signal from controlling signaller
- Competent worker to pilot train into section
What Safe Working System does the MURL operate under?
The bi-directional ABS Safeworking System
What is the only type of signal found within the MURL?
3-Position Light-Type Home Signals
What signals within the MURL require a Signallers Caution Order to pass at stop? Who sends the order and how is it received?
Only signals protecting points require a Signallers Caution Order.
It is transmitted by the Area Controller (authorised by senior network controller) via the DTRS or Signal Post Phone (or handed)
What additional task must a driver do in the MURL if the route line is not displayed?
The driver must manually check/lock the points
What authority does a driver need when passing Intermediate Home Signals in the MURL that are not protecting points?

Under what circumstances is each method given?
Handed or Dictated (never transmitted)

Remote = dictated
What scenarios can a Train Authority form be used?

noooo this question is not true I don’t know where I pulled it from
Under ATC, what authority must a driver have to pass a Dwarf when its is controlling the entrance to a single-line section?
ATC System Caution (or Train Authority as required)
(This is because the Dwarf is acting like a Home Departure signal)
Under ATC, what exceptions do we have for passing a Home Arrival signal at Stop?
- Defective
Under ATC, what authority must a driver have to pass a Home Arrival at Stop, and how is it received?
If the signal protects points, the driver will receive a Signaller’s Caution Order.
At locally controlled crossing loops, Caution order will be handed if appropriate.
