150
If you needed to prep a train, what abbreviations would be on your schedule card?
PP (partial prep) PB (prep from berth)
151
Explain the acronym ASKDM?
This is used to aux on correctly. A - Press aux on for 5 seconds S - The speedo will perform a self test, to around 90mph K - Key on - DDS neutral D - DC systems selected M - MCB close
152
What would you do for the rest of a train prep AFTER you have completed ASKDM?
Check the cab from left to right, starting from the top and moving left to right, checking all lights, logging into MITRAC, testing the bell buzzer, perform a personal brake test, complete test of the cab buttons, check the DOO monitor works, T test button on GSM-R, test PA and c2c. Check for emergency equipment. Walk through the train and check internal doors are working and BECs are closed. Then test other cab in entirety.
153
Would you need to aux off and aux back on in both cabs when prepping?
No
154
If you encountered a defect, what would you do before contacting the signaller, and then fleet?
Spend two minutes making sure that there isn't an easily rectified issue before reporting. Also make a PA due to the delay.
155
If your train fails to take power, what cab checks would you make?
Check the line light is illuminated. Traction status screen. DRA isn't on. MCB's MCB/ADD light isn't illuminated.
156
If you encounter an unsolicited brake application or you cannot get your brakes off, what in cab checks will you perform?
BLIMMMED Brake demand light Look out of the window - Fire/BIL light Interlock MCB's MITRAC Main reservoir pressure Emergency stop plungers Drumswitch - should be uncoupled
157
What could potentially happen if you had a leak on a tank?
You could lose air pressure resulting in an emergency brake demand. If it was the main reservoir tank, this could lead to an emergency brake demand from the LMAG (because the main res pipe pressure is too low). If it was a brake supply reservoir, the demand could be due to the LBSRG. Parking brakes might also be applied, depending if the air pressure in the main reservoir pipe is sufficient enough to keep the spring loaded brakes held back or not.
158
Why would you need to operate the MRPIC?
The main reservoir tank has burst, and you need to isolate it from the main reservoir pipe. (Main reservoir pipe isolation cock)
159
What MCB's would you operate when you have activated the MRPIC?
You would need to trip the compressor MCB's. This is because it will run constantly, and becomes a fire hazard.
160
If you are a single unit, what does operating MRPIC mean?
You no longer have a compressor keeping the air systems pressurised, therefore you require assistance. Parking brakes will be applied due to low pressure. Emergency brakes applied.
161
Why would you operate the BSRIC?
BSRIC (brake supply reservoir isolation cock). Isolated when either the brake supply reservoir has burst, or you are unable to access the BCIC (in a station/ viaduct etc.)
162
What else would you have to operate following operating the BSRIC?
When the BSRIC is operated, emergency brakes are applied due to the LBSRG. The train cannot be moved without the use of the EBS (emergency bypass switch)
163
If you have isolated the BSRIC in the leading DMOS, would MADEMAD be satisfied?
No, the **AIR** monitoring the brake cylinder pressure on the duplex gauge would not allow EBS to work. Assistance required.
164
Explain MADE MAD?
M-MCB TPWS/AWS (behind your head) M-MCB Brake control (in the body end cupboard) A- Air in main reservoir pressure (left hand side of duplex gauge) A- Air in brake reservoir pressure (right hand side of duplex gauge) - gauge only shows the pressure in the leading DMOS D- DSD D- Drumswitch - it should be in the uncouple position E- Emergency plunger
165
If you had dragging brakes, what would you ideally operate?
The BCIC (brake cylinder isolation cock)
166
If you have isolated one set of brakes on a 5 car, what are your restrictions?
A restriction of 10mph below line speed down to 35mph.
167
If you have isolated two set of brakes on a 5 car, what are your restrictions?
Detrain. Drive at a considerably lower speed in order to control the train.
168
If you have isolated three sets of brakes on a 5 car, what are your restrictions?
Do not move. Assistance required. Recalculate when attached to assistance.
169
If the compressor is not switching on, what would fleet ask you to operate?
They would ask you to operate the CGIC in the hope that the compressor would then run continuously.
170
If the CGIC was operated and the compressor still didn't come on, what is the problem?
The problem is then with the compressor. If you are a single unit you now have no compressor and require assistance.
171
If the horn is sounding and won't stop, what will you do and when would you report it?
If the horn is sounding continuously, it needs to be isolated. If it's isolated then it's a total failure. Total failure requires reporting immediately. Contact signaller and then fleet. Detrain. Max speed of 20mph. Stop to inform PWAY workers of defect.
172
If you have a total headlight failure, when would you report it and what restrictions apply?
Report immediately. Detrain. A substitution light must be positioned forward. Max 20mph. Use the horn.
173
If you fully isolate a switch on the safety systems panel, what indicator would be illuminated in the cab?
safety systems isolated light (next to AWS reset)
174
Your AWS MCB on the cab back wall trips. When would you report it? Would fleet ask you to operate and what restrictions apply?
Report immediately. Fleet would ask you to reinstate (3x) Fleet would then ask you to isolate the AWS safety systems isolation switch. 100mph with a competent person (with route knowledge) 60mph without. Maximum 40mph in darkness/poor visibility (with and without a competent person).
175
What is special about the full isolation of AWS/TPWS?
It is a rule that is published in RSSB TW5. It cannot be altered by different TOCS, all must adhere to it.
176
Something is stuck under the DSD, so fleet have instructed you to fully isolate. What else would you be asked to isolate and why?
They will also ask you to isolate the vigilance alarm. This is because without the DSD footplate active, you are unable to reset the vigilance alarm, therefore an emergency brake application will apply.
177
What speed restrictions are in place for a full DSD isolation?
Report immediately. Detrain at the first opportunity. With a competent person, line speed is allowed. Without, maximum speed of 60 mph. **IF AWS/TPWS IS ALSO ISOLATED** maximum speed of 40 mph and the competent person is mandatory.
178
If the vigilance needs to be isolated, do you need to isolate the DSD too?
No, but the DSD must always be kept down unless the train is stationary and in neutral.
179
If a door is stuck open, what might fleet ask you to operate?
The TIS - traction interlock switch.

When a failed train is clearly visible, is GSM-R contact required between the driver's?
No
210
If the failed train is not visible to the assisting driver, how will they communicate with one another?
The signaler will patch the assisting driver through via the GSMR
211
What happens if the failed train is not visible to the assisting driver and the signal is unable to patch the drivers through to each other?
The signal acts as the middleman and relays messages between the two
212
When rescuing a failed train, What happens if the drivers cannot be patched through to one another and there is poor visibility?
The driver of the failed train walks 300 m towards the assisting train. They require a red light or flag.
213
When rescuing a failed train, What happens if the drivers cannot be patched through to one another and there is poor visibility, but there is a signal nearby?
If the stop signal is within 300 m of the failed train and in the direction that the assisting train will be travelling from, the driver will wait at the signal providing the signaler confirms signal protection.
214
When rescuing a failed train, What happens if the drivers cannot be patched through to one another and there is poor visibility, and the driver is required to pass through a tunnel to reach the stipulated 300m?
The driver does not enter the tunnel but waits at the entrance.
215
If a train fails in the tunnel and a driver is awaiting assistance, what should the driver do?
The driver needs to walk to the exit of the tunnel, in the direction the assisting train will travel from.
216
What does it mean if a red triangle appears at the top right hand corner of your MITRAC screen?
There's an unacknowledged MITRAC red or yellow fault
217
If you had an unsolicited brake application, what will you do? What checks will you perform?

218
If you couldn't take power, what would you check in the cab
Check the line light is illuminated. Traction status screen. DRA isn't on. MCB's MCB/ADD light isn't illuminated.
219
What's the name of the coupler on the front of the train?
Dellner
220
Why would you operate the CGIC?
The compressor isn't running. This is to check whether that is due to a fault with the compressor governor. By isolating the CGIC, the compressor should run continuously
221
How many MRPCC isolation cocks will you operate?
4
222
If your MCB/add light is on, what screen will you check on MITRAC?
Traction status
223
If you've operated the AMRIC, will it have any effect on the train?
No, this isolates the supply to the auxiliary main reservoir. The compressor will still work adequately
224
If you've operated the BSRIC, what must you then operate?
EBS. This is due to emergency brakes being applied as the LMRSG is unsatisfied
225
How do you reset the emergency plunger?
Twist the plunger, reset the MCB
226
What screen do you use on MITRAC to isolate a door?
The settings screen. Select the relevant cab, then choose the doors you'd like to isolate.
227
What coach would you find MRPIC?
PTOSL
228
How do you reset a smoke alarm?
Reinstate the two MCBs in the body end cupboard of the affected coach.
229
What does it mean to propel a train?
To push a defective train
230
Why would you propel a train?
There is a failed train on the mainline.
231
Who authorises and controls a propelling movement?
A CDM/ OIM
232
Explain the role of the CDM/OIM when propelling
They ride in the leading cab, authorise and are in control of the movement. 5mph max speed if the parking brake is the only way of stopping the movement.
233
When would there be a max speed of 5mph during a propelling movement?
When the only way of stopping the movement is by using the parking brake in the leading cab.
234
What do we need to isolate when propelling?
TPWS temporary isolation.
235
Why would we need to temporary isolate TPWS during a propelling movement?
The leading cab (which is NOT keyed on) will pass the signal first, changing the aspect to red to protect the section. Because the driver is keyed on in a coach further back, their magnet will then trigger the now live TPWS TSS, resulting in a brake demand.
236
When propelling in the depot, who is in charge of the movement?
The shunter
237
Where would the shunter be when propelling in a depot?
Wither in the leading cab, elsewhere in the leading vehicle or outside the train in a safe space.
238
What is Hauling?
Pulling a defective train
239
When Hauling, where does the competent person ride?
In the middle cab, ready to apply the emergency brakes should the train divide.
240
If you are in a failed train and waiting for assistance, what will the signaller expect from you?
That you will remain on the train. That you will relay any information. That you will wait for assistance.
241
What are the four possible outcomes when declaring yourself a fix or fail?
