recently purchased TMCC setup with 50th anniversary union pacific set and the hrn, bell reverse direction, brake, smoke buttons intermittantly respond the lights on the unit come on when I press the associated button but over 50% of the time the i get no sounds, reverse of driection etc... i also have a sound dining car in the set which seems to operate flawlessly...do i need to reprogram the engine, any instructions on how to do this?

I really don't know too much about TMCC myself, but I would highly reccomend posting this topic in the Classic Toy Trains forums. You'll get much better results.
