Thank you so much for your reply. I've tried each of the numbers, but unfortunately nothing seems to work.
I'll keep on trying to find someone nearby to help me.
Once again thank you to everyone for your assistance.

Hi Mark

Sorry I had never heard about resetting. I livev in an area in South Africa where model railroading isn't well know. In fact there isn't a hobby shop around,so going to a place to meet and discus things doesn't happen.I've got an older EZ Command controller,  so I'm embarrassed to admit that I've tried what I think you have told me to do, but still nothing. While trying to reprogram, and when i set it on 10,the analogue address,  the unit staeted running,  but I couldn't stop, speed up or sliw it down. When I  removed it and turned of the command unit, and put the unit back, and then started everything up, there was nothing. Completely dead again. I'm  thankful for your assistance and truly hope you could suggest something.
Thank you.  Regards, Brett
