Fire extinguishers Glow sticks Egress and Passcomm handles are normal No doors are locked out of use MCB panel closed FIP panel closed PANIC cover closed Emergency cupboard in tact
53
During prep, what are the main things you look out for when you walk clockwise around the Unit?
Check the front of the train: Lamp iron is down (tail lamp bracket) Any damage to the windscreen Any damage to the windscreen wipers Lights are ok, no broken glass TAC looks ok and the electrical covers are closed Walk around the Unit..... Drum switch is in the correct position DIC is in line (should be horizontal) Lifeguard is undamaged Axle Box is ok Primary and secondary air suspensions are ok (rubber leaves and air bags) General condition of the train (I.e. windows, body of train) Butterfly flaps are there for all doors Listen for any air leaks Sand box clips are in place Sand pipe is in line with the wheel All covers are closed on the Brake Frame Assembly Shit tank is closed Check all cables are undamaged (I.e. 1500 and 240 AC etc) MRPCC are in downward position Transformer Qualitrol valve is not sticking out
54
If you have to isolate the air suspension due to one of the air bags being damaged..... after you have isolated the relevant ASIC on the vehicle (WMT Control will tell you which one), what do you have to remember to do afterwards?
Drain all the surge tanks on the affected vehicle
55
What does the safety valve look like on the Transformer?
It is a shiny brass valve
56
If the FIP in DMS A says you have got a Traction Fault, but the Local Fault light is not lit..... where is the problem?
DMS B
57
What if the Main Reservoir Pipe bursts in the DMS lead vehicle and you're not getting assisted...... what are your actions? (remember Train Wire 13.....)
Operate the MRPCC (Main Reservoir Pipe Coupling Cocks) BIC the DMS and do rotational test Lock doors out of use and remove passengers Change ends and EBS in the rear (you will now be driving from this rear cab..... remember EBS does not resolve faults in the leading cab which is why you operate it in the rear cab) Guard travels in the (what is now) rear cab and operates the parking brake in an emergency 5mph max
58
During prep, when walking around the outside of the Unit.... how can you tell that one of the Isolating Cocks have been isolated?
Look through the windows on the manifold cover and if you see white then it means that something has been isolated
