John,
Most if not all of the Baldwin VO-1000 switchers had the same turbo generator like device on the top of their hoods in front of the cab. A number of photos are available in the Spoor books and I believe, somewhere in those books, I recall a description of the device. As you have suggested, it was a generator for the radio. I am not sure how it was driven as the switchers had no steam source. possibly, it was a modified turbo generator that was driven by air. I am not home, so I can not check my copies of the Spoor books at the moment.

I suspect it IS to run the radio, as the locomotive in question features the "wagon wheel" antenna at its usual location among the radiator shutters...but why would the Q (presumably) use a cast-off steam loco turbogenerator for power when there's a rather large generator (800-1200 hp) directly below it?
