I have an old Bachmann F7 (DC) on a DCC layout.  It runs the opposite direction than my DCC engines.  How difficult is it to rewire the diesel so that forward on the throttle is the same direction as the DCC locos & what wires need to be changed?  Thanks.

I have a Spectrum 2-8-0 (HO #83601) that needs repair.  (Train was left unattended on a Christmas layout & got hung up on a plastic tree that fell over the track.  Believe the gearing is damaged.  Also messed up the side rods/linkage.)  I've sent two service request to Bachmann & have gotten no response (other than providing a repair order number).  Is there anyplace (else) that I can get this engine repaired (out of warranty)?
