I usually run 2 or 3 locomotives at a time on my layout. Now when I stop one locomotive and switch to another, the first one continues to move, even though at a very slow speed. I can't get it to stop. Any ideas as to the problem. It just started doing this.
I would look in the troubleshooting guide of your EZ command manual... Maybe your not doing something right
One thing I'd try, if you have access to another controller, is to reprogram the decoder.
