Well it also has a trolley pole and a smokestack, so it could have another purpose. Probably not powered, but it could be some kind of MOW car using electricity to power something.
Or it could have been used as the lead car for something, hence the headlight, and the trolley pole to trip grade crossing sensors. Pacific Electric had some diesel switchers with trolley poles on for that reason.
It appears to have un motored bogeys. I can't see any fittings you would find on a motored bogey.
