Gentlemen thank you for your excellent suggestions.
PhillyReading- I am fortunate to live near a reputable Lionel repair shop.
KENV-I tried your idea to reprogramming. Unfortunately, when I applied power to the track, the engine would turn on with sounds and the light board lit up. It appears that I can’t get engine to go into program mode.
BIGDODGETRAIN- the 6 dash number is 6-34613.
ROYBOY- It ran properly when I purchased in October 2016 until last Friday.
GGG- I run it in command. The program switch was set to RUN the last time it worked properly.
GUNRUNNERJOHN- I checked all connections and find them to be good. Could there be an issue with R4LC?
Again, I want to express my appreciation for your time, and assistance. At this point, I may bring it to my local hobby shop for their expertise.
Sincerely,
Frank
