Locked in conventional mode

Do you have a Lionel repair shop nearby to you? Or maybe you can get a friend who is knowledgeable with newer Lionel trains to look at it for you. To be honest it sounds like there is a problem with  the engine, not sure what.

try reprogramming the engine.  through your owners manuel

what is the 6 dash number?

Has it ever run properly for you? Or did you buy it this way?

Do you have command or just run this conventionally?  Read manual, there is a program switch on TMCC/Legacy engines.  Is it in RUN position?  Needs to be.  G

If by "running", you mean the sounds come on, and only the number boards light, top suspect is the R4LC fell out of the connector.  The fact that it won't move and the lights are all off suggests to me that's a likely suspect.

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

Ok sounds like it is not seeing Command signal so Radio board or antenna is suspect if other trains run on your layout.  G

Since the lights don't come on, it's not just a lack of signal.  In conventional mode, the lights would come on.
