Thanks for the reply. I tried a second locomotive that I have just to be sure that it was the controller and it ran at full throttle as well. I already scheduled the repair with Bachmann so she will be on her way for repair once again. It really makes me wonder about the long term reliability of these EZ controllers? Hoping it's just bad luck on my part. I am very pleased with the system Bachmann has in place for warranty repair just wish shipping was included.

Are these controllers all junk? I bought my son this set for Christmas and the controller was dead out of the box. Just received a replacement back today and it is yellowed and obviously used. All the functions work but the train runs at full throttle no matter what position the speed knob is in. What is going on with this Bachmann controller? Am I doing something wrong? I bought a cheap Bachman DC controller just so my son could play with his train 5 weeks after Christmas. It works fine with that controller but connect the DCC EZ command and the train has no speed control. Any help would be appreciated.
