Allegheny, if you use the train with the 3 coaches in the set, the original motor will be OK and enough strong. No problem.
Gentlemen,
Thank you for your advise as I really wanted to get this set for him.
I'll consider the motor replacement.
The issue is I just don't have that kind of free time until I put an end to all of my charitable activities as I'm still working fulltime.
If the upgrade were a simple drop in - no problem, but it seems you need to build an appropriate shim. Not sure if a metal one is really needed vs. a plastic one which can be made a lot simpler.
The removal of the worm gear and its replacement - isn't clear to me. Is it pressed on and can it be removed from one motor to the next without breakage and bending issues of the motor shaft and worm gear?
