Blimey. Your really gonna push my brainbox here
1. Only ones I see missed are master controller and drum switch.
2. Dont forget if you were isolating a coach it wouldn't be via the MRPIC at the coupling blocks. It would be the yellow handles on the MRP pipes between coaches. To answer your question...Yes because if a coach isn't receiving an air supply its LMAG will operate.
3. Wire 13 is fed by the battery. Also see point 9. under 110v
4. This isn't something you need worry about. Just know that if either trip you will get an emergency brake application. Because of 3.
5. Some of these will open the VCB. These ones can be remedied temporarily by pressing pan up/reset
- Any Surge on the motors + (isolate motors whichever end has a fault light lit)
- Earth Fault on any of the motors + (isolate motors whichever end has a fault light lit)
- Primary and Secondary Overload Relay Flags for the transformer in the Fault indication panel (FIP) Cupboard in the PTS coach.
- Traction control MCB in FIP.
These will not and you a dead duck.
- VCB Governor. Even if you can find the air leak not much you can do about it.
- Transformer temperature relay Flag in FIP
- Low Oil level in transformer oil pump.
- Gas or air in the oil via the Bucholz.
6. Egress, Pressing the couple button when there is no other unit or the drum switch in the coupled position on the outer ends. (Train basically thinks their should be another there) this can happen often after uncoupling, quick push of uncouple again does the trick. Faulty door. Taking out your door key on the move and putting in in again
Door Control circuit breakers although not sure which ones off the top of my head. Two door keys in.
7. Your minder will go over this with you.
8. Put simply no. No power. No motors. No go.
9. 1050/900 are for the motors only. 240 auxiliaries for the Transformer oil pump, coach heaters, headlight via an inverter and battery charger. Also provides 240 volts AC to the auxiliary transformer & rectifier which together produce the 220 volts DC which runs the main compressor, 110 for radio, PA, aux. compressor, cab controls and all control circuits such as door and brake circuits.
