What do you do if the OLE is about to be turned off for an extended period of time? (What do you do in the cab and why would you tell the guard?)
Tell the Guard to inform the passengers that the lights will be going out
(If in platform or really high temperatures, remember to open the doors… because you will also lose air conditioning)
Lower the Pantograph
Switch off the batteries
Inform the signaller
If the OLE has been switched off for a long time, what do you do when line voltage returns? (Remember you would have dropped the Pantograph and switched off the batteries…. what about the AC/DC). Why would you check the TMS after you have raised the Pantograph?
Switch on batteries
Put the drivers key in and open the desk
Select AC
Wait until the Auxiliaries Low Pressure light goes out

If you are a single Unit 350/3 and a fire is detected in the ACU, the VCB will open. If you have come to a stop and need to move to a safe location, what button can you press? (….Remember if there is more than one unit coupled then the VCBs remain closed on them and you still have power and therefore would not use this button)
Fire System Bypass button (works for 4 minutes until the VCB opens again…. automatically)
(You can only press this button ONCE)
If the Pantograph is damaged, what cock (located in PTS low level cupboard opposite the UAT) needs to be isolated prior to the crossfeed procedure with an assisting train? (AARC)
