Tried everything... no luck.  Took the controller and the engines down to my local hobby/train shop and tested on his layout.  Engines worked fine with his controller.  Switched controller and nothing else and nothing worked.  Controller must be bad.

All of the engines were working fine this month.  Sometime after my son was experimenting with a new layout they stopped working.  This happened once before and we re-progammed each to a new address and they worked fine.  Now, all three won't run on any address.  I don't know of a way to reset the engines to a factory default.  They have only been used on this EZ Command control.

I have an EZ Command Control Center and 3 Bachmann DCC engines, all three exhbit the same problem.  The trains don't move - no mater what I try, no forward or reverse.  I have re-progammed them each several times.  They properly do their little move when programmed.  The lights properly turn on and off and properly light when in forward or reverse.  But will not move normally at all, no matter where the throttle is set, nothing happens.  I have tried them on a simple circle of track.  Help! Thanks!
