My Thomas is 0 gauge.  The controller that came with the set is blue with a red dial.  For some reason even with fresh batteries, the controller will not turn on and connect to Thomas so that he can be run.

Maybe my best bet is to try the controller that I have for a Mickey Mouse train with Thomas.  That should establish whether or not a Lion Chief Controller will work.

Thanks for the response and the request for more information.
