How do they change the power from diesel to third rail if the engineer is in the cab car?

There is no separate dynamic braking. The engine is equipped for blended dynamic braking when in diesel mode. In electric mode, the blended brake is disabled as the dynamic brake resistors are used as part of the electric propulsion circuit. The FL9AC did have blended dynamic brakes in electric mode. They were designed to provide gap protection to the HEP in GCT. A great idea that never worked very well.

It is certainly true that blended (or dynamic) brake is disabled when the locomotive is in electric mode, however an AC propulsion locomotive has no use for grid resistors as part of motoring in electric mode. The traction inverters of the Genesis locomotive are connected to the 3rd rail by way of the 3rd circuit breaker and two line filter reactors. GE made no provisions to allow for dynamic (or blended) braking when operating in electric mode.
