Bach-mann
The engine is a 1870s because the engine is not in the tender.
Thanks
Arthur
P.S. Is there any tests I can make to find out if it is indeed the drive shaft.

Dave,
The engine is a HO Model.
Thanks
Arthur

I have a Bachmann 4-4-0 Steam Engine,that I cannot get the main drive
wheels to turn.Being new to model trains I need to ask a question.I have
noticed that there is a plastic ring above each of the drive wheels does
this ring keep the wheels from turning,or do I have another problem?
Thanks for any help you can provide.
Arthur
