Ho Union Pacific generator car 206b. I don't know much about this interesting piece of equipment but that it was acquired by UP sometime in the early sixties from Great Northern. They converted sever old northern tenders into generator cars. It has a 12-567 emd and 480 and 220 outputs. Also has a steam generator capable of supporting up to 10 coaches.

The model is very nicely done, has great piping details, see thru fans and walkways and end plumbing/safety chains, etc. Looks great at the head of a passenger consist!! And something you don't see very much of!
