List the two potential problems with GSM-R……?
Unable to register due to signaller failing to set up
Speaking to wrong signaller due to cell overlap
If you’ve got a leak with one of the air systems (Brake Reservoir Tank, Main Reservoir Tank, Main air pipe fracture), what isolation cock would you operate?
BIC (with the Brake Reservoir you would also BSRIC)
(Remember, Train Wire 13 goes through the Train Brake MCB, Local Brake MCB leading cab, Brake Supply Reservoir Governor and also the Main Reservoir PIPES air leak… so you would also have to EBS)
Do you have to BIC if
1. Local Brake MCB tripped?
2. Train Brake MCB tripped?
3. Auxiliary Supply MCB tripped?
4. Auxiliary Control MCB tripped?
- Yes
- No
- Yes, once mechanically coupled to assisting train
- No

- Yes, but ONLY if tripped in leading DMS
- Yes
- No
- No
If the Local Brake MCB has tripped, which 2 safety systems would you need to isolate? What would you also do with the passengers? What isolation cock would you also isolate?
EBS only if MCB has tripped in leading cab

The second set of double doors
Driver’s side
If you look at the outside of the TS, underneath which feature of the train would you find the Brake Frame Assembly? Driver’s side or non-driver’s side?
The second set of double doors
Non-driver’s side

Provides power to the TAC
Provides power to the 27 and 60 Way Jumper Cables (between the vehicles)
Charges the batteries (hence if the MCB trips the battery charger light turns red!)
When you raise the Pantograph, what air pressure should be read on
A. Main Reservoir Pressure
B. Brake Cylinder Pressure
A. 7 Bar
B. 4.5 Bar
What is the only difference in the remedy if the Local Brake MCB trips in each of the vehicles?
You would only EBS if the Local Brake MCB trips in the leading DMS….. you would not EBS if the trip occurs in the other vehicles
(You would however still….. 3X MCB - inform signaller & Control - BIC - PCIS - Transfer PAX and lock doors - 5mph)
Do you have to EBS if the Train Brake MCB trips in either the leading DMS or the rear DMS? THINK….. What happens if the Leading DMS MCB has tripped, do you still EBS?
Yes (remember train wire 13)
(If you EBS from the leading cab you will need to drive back the other way because REMEMBER…… EBS ONLY RECTIFIES THE FAULT IF THE FAULT IS IN THE LEADING CAB IF IT IS THE LOCAL BRAKE MCB!!!)
There is one big difference in remedy if the Traction Control MCB trips in either DMS or the TS (loss of traction power and regen braking). What is that difference?
If the MCB trips in either DMS you can operate the Traction Control Cut Out switch and you can continue….. if it trips in the TS then the VCB opens and you will need assistance
Which of these tripped MCBs would always require an assisting train…. Auxiliary Supply, or Auxiliary Control?
Auxiliary Supply MCB
