<p>My favorite exhibit was a mockup of the cab of a German (DB) electric locomotive, probably class E-10.  You could operate the controls, and a simulator showed what was happening.  It was probably used for training engine drivers.  The E-10 was used in major passenger services.  It was later called class 110.

No, that is not a steering wheel.  It is a throttle, regulating the amount of power given to the locomotive.  The knob to the left is the "dead man's throttle."  You have to press it every so often.  Otherwise it gives a warning, and if this is ignored, automatically engages the brakes to stop the train.
