I believe so, what little research I've managed suggests they were the the main motive power on the Clayton West line (about 300 yards from where I'm sitting now) and the Holmfirth branch, both of which are routes I'm using as a guide for my own layout when I eventually get started. It's completely anachronistic compared to the rest of my fleet, but it'll be my railway so I'll run what I want!
Thanks for the tip, I still need to get my head around the quirks of DCC. I haven't got anything done on my layout as yet, I posted an update in the Projects thread so I won't repeat myself. Anyway, got to go as I'm in a bidding war!
Postscript: won the two items I was after, also tried Function 2 for the braking and it's done the trick, so thanks very much
@Iskra ... turns out the flywheel wasn't quite as impressive as I thought, if it had been I think Bachmann would have been in line for a Nobel prize for inventing a perpetual motion machine!
