[terminologist]

Hi,

I'm new to the site, so apologies if I've posted this in the wrong forum.

I'm trying to come up with the correct terms for the following - if anyone can help, it would be greatly appreciated.

1. A diesel railcar which also has its own heating unit. Heat-engine railcar? Heat-engine traction unit?
2. Railcar - is that the right term, or is motor coach/motor car better?
3. Multiple heading v. multiple traction - which is better?
4. Are the terms 'hauled', 'towed' and 'pulled' interchangeable, or is there a preference for a particular one?
5. Ditto for 'banking' v. 'pushing'.
6. A locomotive that recovers a train from the track - recovery locomotive, breakdown locomotive or emergency locomotive?
7. The name for a trackside winch unit (housed in a cabinet) which is used to manually operate switches/section insulators on an overhead line (may be obsolete technololgy, I'm not sure).

Sorry for the odd jumble of questions. If anyone can help, that would be fantastic!
