I think you're right about the sound -- would want to have a Rolling Thunder subwoofer, no? And wouldn't there have to be some concealed smoke generators and fans or whatever down under the roadbed somewhere?
I think sound might also be a requirement for more realism. (Another reason why I don't use, or need, DCC.)

One of the model magazines once published a tip for connecting lighting in model buildings while allowing them to be easily lifted off the layout. A hole was drilled part way through the layout surface and filled with mercury. A wire from the power supply was placed in the mercury and another wire from the building dipped into the mercury when the building was placed on the layout; a kind of open faced mercury switch.
