I operate a Bachmann On30 train around the Xmas tree using EZ Command DCC.

I've been doing this for several years but when setting up this year, I failed to follow this note in the instructions:

NOTE: DO NOT CONNECT THE E-Z COMMAND CONTROL CENTER TO THE WALL PACK POWER SUPPLY UNTIL YOU HAVE MADE THE CONNECTIONS FROM THE CONTROL CENTER TO YOUR TRACK.

Now my locomotive will not run -- lights and sound all work but it will not move in either direction.   What have I done, did I fry the decoder?
