Thanks MUCHO to those that replied.I will keep a watch here and see what happens.

Well, truck #4 has joined the stable of loud clicking, non moving rail trucks on my short line.
Does anyone sell replacement gears so I can get these guys running again?
Any help would be greatly appriciated. Thanks

Thank you gentalmen for some great and thoughtful information. It is the people, not the activity, that makes a hobby great.
Thanks again.

Thanks for all the basic info. Rather than boring all to tears I omitted detailed explanations about all the tests made prior to posting the question "Does Bachmann sell replacement boards for decoder ready On30 forneys and if so does anyone know where to obtain them?
Thanks again for you time and input.

I RECENTLY ADDED SOUND TO MY DCC DECODER EQUIPED On30 FORNEY AND IN THE EXCITEMENT OF THE MOMENT I OVERELOOKED A COUPLE OF BARE WIRE COMING OFF THE REAR TRUCK.
WHAT GREAT SOUND UNTIL ALL OF A SUDDEN NOTHING!! NO LIGHTS, NO SOUND, NO MOVEMENT.
I'M THINKING I FRIED EVERYTHING BECAUSE EVEN WITH THE DC PLUGS REINSTALLED IN THE FACTORY BOARD THERE IS NO SIGN OF LIFE.
ARE THESE BOARDS AVAILABLE AS REPLACEMENTS AND IF SO HOW DO I OBTAIN ONE OR SHOULD I JUST TAKE IT OUT AND HARDWIRE A NEW DECODER?
THANKS FOR ANY HELP YOU CAN OFFER.
