After working fine for a couple of years my Lionel TMCC loco will not respond to TMCC signals. We are running two separate loops, both powered by postwar ZW, and using the Command Base and do not use Powermasters. Our Atlas diesel responds to commands on both loops so I have ruled out Command base and wiring problems. The Lionel loco will not respond on either loop.
We have followed the instructions to reset the loco with no success. I first followed the directions that came with the loco, then tried the reset directions listed in the TMCC book.
The loco is the Mikado Jr from the Hot Box Reefer set.
We have cleaned the track and the pickup rollers and wheels.
Any suggestions greatly appreciated!
