Thanks, David... I will try to put future posts re this matter with my other thread.

In re previous post/question about my current failure(s): I have been in contact with the nearest (Savannah, GA) dealer - where I first purchased my Digitrax "Super Empire Builder". Following many of the tips posted here, I think I have narrowed down my problem to a possible failure with the "Magna Force" power supply (so much for electronics/products manufactured in China...)...but I digress. I will drive the 115 miles to Savannah and have the LHS check everything out. I wanna thank you guys for your posted responses; the tips and suggestions continue to be extremely helpful.
