Well, I can't tell you a lot about the motor, I just sent it to Frank Timko and asked for a more powerful motor. As for what adjustments were made to fit it, I see where he took a little off the sides to clear the wheels, obviously put the matching worm from the old motor on, and in the one shot you can see the aluminum block to align it.
The command upgrade was an ERR Cruise Commander Lite and the RailSounds Commander (Small Steam). I also added a Super-Chuffer and a fan driven smoke unit. As I said, this is a second locomotive that I'll upgrade now that I have it.
