Brent has a model RR problem and wants help from readers:

“I have Walthers budd lighted passenger cars that at some spots on the circuit the lights flicker. I have cleaned the track etc, but to no avail. My units are new. Does anyone know what to do?”

Joe asks readers with DCC experience:

“I am unable to program my control to move two trains on my track.”
