I own the above diesel since new. I run an ABBA lashup with the full set of passenger cars. The forward A is powered, the next B is also, then dummy B, dummy A. It was upgraded to BCR 3 years and running well. Tonight it started up, ran with full power/lights/sound like normal. Went upstairs to dinner, then came down to run the train again as before. Normal startup sounds, went forward again short distance, then dead silence and stopped. Checked- all connections are good- nothing is derailed either. All cars light up, so does the other dummy A unit. There is no read light on the MTH transformer indicating a short. Really weird. 
Don't understand why this is happening? Can a BCR die? Or what else should I be looking for?
Thanks in advance.
