My friend, Tom Matty, who models the Thomas Sub of the Western Maryland Ry, a very skilled and talented modeler, offered to do a writeup of how he re-motors an old Proto2000 GP7/GP9 with a much higher quality Kato drive. It involves milling the frame, fitting the motor, linkages and worm gears and then installing your favorite flavor of DCC/sound. (we won’t cover the DCC installation here today). Tom gave me permission to post his process on the blog so I figured I’d share it with everyone who may be interested in this fantastic upgrade.
