Help please??

[Parolaccia]

I have the Pacific Flyer train with the EZ Track and the controller that comes with it. My father in law recently gave us his old McKinley Explorer HO set that has a GP40 diesel engine. When I put this engine on the tracks it moves about 1/4 inch and freezes. Does this type of engine require different tracks or controller? Or would it be something with the engine itself causing it not to work? TIA

Certainly more info is needed...

Define "freeze" would be a good place to start

Do the wheels still turn?
Does the lighting work?
Do the wheels look dirty?

Does it do the same forward and backward? Does it seem like one of the trucks is being dragged along?

This locomotive does not require different track or controller, though the cars should be run on 22" radius curves rather than the 18" radius ones in the pacific flyer set.

I suspect you have a gear bind somewhere. You could try looking for grit or other obstructions in the gears. Bright light and a magnifying glass will help you with this. Take the body shell off, and turn the locomotive over, wheels up. Gently turn the motor shaft by hand, and when you feel it bind up, carefully look for grit where the gears mesh. You can clean it out with a toothpick.
