The cubicle switch door in 50030 is seen partially wired. The controls are: ammeter (top), emergency compressor switch, passenger/goods switch, exhauster cut-out switch (2nd row), control sut-out switch (3rd row), with the fuel priming and local engine start buttons at the bottom. 22 June 2008.

Eventually this door will have to have 59 wires run to it. This picture shows a close up of the largest of the new rotary switches, the Passenger/Goods brake selector switch which is seen during wiring. This switch selects either air or vacuum brakes and passenger or goods load. 2 June 2008.
