The F7B units that provide power to the rotaries also have steam generators (they are old passenger units) that provide heat in the rotary cabs. How well they do it, I'm not sure, but the steam generators had steam coming from them this morning at Roseville. The 567s in the F7Bs are wired to traction motors in the rotaries that turn the blade. The F7Bs are "snails"...they have no traction motors in their trucks, which is why the rotary sets require units to move them.
Hope this helps.
