I recently purchased a Bachmann HO scale Jingle Bell Express train set, model #00724.
It came with a USRA 0-6-0 locomotive.
QUESTIONS:
•   Is there a DCC version of this locomotive available? (One that will match the Jingle Bell Express theme?)
•   If not, can the locomotive I received be converted over to DCC? (What would be required?)
•   And/or, if I purchased a different DCC USRA 0-6-0 engine, would I be able to swap the engine housings (or shells) from one to the other?
A prompt response will be greatly appreciated!

Does anyone out there knows if there is a way to set  up an HO DCC locomotive with sound & E-Z Command so that the diesel blast sound goes off automatically at certain section of track?
And if so, how would I go about accomplishing this?
Thanks, Dave D

How can I tell what kind of Bachmann locomotive I have. Is it an F7, F7A, F7B, EMD F9, etc...? (see attached photo)
Also, depending on what type of locomotive I have, how do I convert it over to DCC (with sound)? And what would I need to do so?
All I know at this point is that it's a made in China Bachmann locomotive that was distributed through Hawthorne Village.
I'm very new at this, so please bare with me. A prompt response will be greatly appreciated! Thanks, Dave D in Newport, NH
