Replacement Trackmaster Motor

I hate to say it but if you’re using Trackmaster 2 engines, simply replacing them is sometimes better than trying to swap out the motors. If it’s a hard to find engine like Hiro, I would swap the motor with another TM2 engine that’s easy to get, like Thomas. One of the few advantages of the Trackmaster 2 line is that nearly every chassis part can fit under another locomotive.
