We bought two geotrax train sets at a garage sale and they were missing the controllers. Is there a way to make our other 2 controllers for the other sets, work with the different trains?

I had the same problem with two of our three engines. I read somewhere that you can get them running by hitting the side of the engine against a hard surface. I can't believe it... IT WORKED! I guess the motor gets **** and hitting it will get it going. All three engines are working now.

Aha! I found this on another forum and it worked for me!

I had some luck using a trick I read on the yahoo geotrax group.
Make sure you have good batteries and hold the controller in the forward movement position. Then run the train forward repeatedly on a surface with friction (I used my pant leg). I got two old trains to work again, and I'm hoping to fix one more.

The theory is that this works because it uses a magnetic coupling instead of a direct drive.

It only took me one super gentle swipe across my leg! Better than smacking/bashing them because that can knock wires loose and stuff. Hope this helps everyone! :D
