Hello; don't know if you were ever answered, but to remove the tender shell to access decoder area:
  2 screws at front of tender underframe that hold shell on - remove;
  pull shell forward a bit to disengage the 2 tabs on the rear of the tender while lifting the front up slightly;
  strait up pull should remove.

Just be careful - tabs can break if not careful.

Hope this helps,
Mike

Hello:

I was wondering if anyone can provide the motor specs for the HO scale Porter 0-6-0T locomotive.  Any assistance greatly appreciated.

Hello:

Might try Shapeways.com - in the miniatures section, trains, HO, they have some 3D printed gears for the old model 4-8-4, which look like they would be useful for most of the steamers Bachmann put out at one time.

I replaced a set of axle centers on the 4-8-4, and they have held up quite well.
