Hello and thanks to everyone.
I recently picked up MTH 30-2414-1 , it's listed as an uncataloged item at mth site.
I want to remove the shell to inspect the "insides" and to fix the crew figure who has come unseated in the cab.
As I look at the owners manual it describes the procedure, but shows an image of the underside with 1 pickup roller per truck.
The loco I received has two pickup rollers per truck.
Can I assume the procedure is the same? Might I have received a different loco with a GP7 shell?
Apologies if this is a silly question, I am trying to learn
