Seeing L11 at Epping last week jogged someting in my mind I've never been sure of: what's the difference between ballast locos and pilot locos? Both are ex DMs of various types and both are (usually) painted yellow.
So
: does 'ballast' refer to the weight of the loco (as in the heavyweight Class 37s) or the type of train hauled?
: do they have totally different couplers or do both types carry both?
: can one type substitute for the other if necessary?
All my reference books refer to both, but none of them makes clear the exact differences between them and I realize I'm now curious.
