Jim, thanks for the info. The hobby shop tested it with their transformer.  I will look thru  the book to see about changing that out.  Thanks again.

Hello, I seem to have a problem that needs solved.  I bought an Athearn train set approx. 1 yr ago for my son. He wanted a steam engine for his layout, my dad purchased a Bachmann/Spectrum for him.  The engine is not running well at all, or it gives me an overload light on the controller. I put his original engine back on and it gives me no problems. He also has another engine which is a Bachmann and it runs fine .

I took it back to the hobby shop where it was purchased and received a replacement.  This engine is doing the exact same thing.  I have checked connections, cleaned the tracks, but have the same issues. The original train that I returned, ran fine at the test track at the hobby shop, so what gives?  -Frustrated before Christmas
