I have what I believe is a ten year old GG 4855 Conrail with dual motor. Although it is about ten years old it is brand new in the box never seen a track until today.  I placed on Lionel O track, made sure the power was to the center rail.  turned on the power and the train lights up and the horn works but it will not move in any direction. No manual came with it - just a single sheet of paper. It says there is a reverse board which I believe takes the place of the e unit. 

I have looked everywhere to try and find out what the problem is with no luck.

Anyone out there have an idea what it may be?

Thanks you in advance.
