My Command Equipped (TMCC) Lionel GP-9 will run for a couple of minutes than come to a complete stop. I suspected dirty track at first, but after a good cleaning the problem remained. I noticed a flicker in the headlight which is a common sign of a weak signal. I doubled the antenna using copper tape and the flicker disappeared, but the problem remained. I then suspected that maybe the R2LC was the problem, I swapped it out with a spare R2LC-04 and guess what, problem solved. But now another problem developed, no horn, bell or crew talk sounds. I went through the setup procedure setting the engine ID and using the AUX1 #5 program code. The only sounds I get are the diesel revving sounds, nothing else. All other TMCC functions are operable. Did I hit a wrong button and somehow turn these sounds off. Any help would be appreciated.
