Mr Union Pacific posted:Someone can correct me if I'm wrong on this, but I'll share my experience with TMCC. I would suggest carefully removing the shell of the locomotive. TMCC locomotives receive commands from the base using the handrails on the locomotive.
TMCC/Legacy is a two part signal. The only direct communication with the base involves the remote. Base location has no effect on track signal.
One side of the signal is broadcast through the outside/common rails of the track via the one wire connection to the common from the base.
The other side of the signal is transmitted via the base wall pack ground lug through the ground wiring in the walls of the room the layout is in.
( Its recommended the base wall plug be plugged directly into the outlet. Power strips and surger protectors can degrade the signal)
The locomotive antenna picks up the changes in the differences of the two signals when the remote buttons are pushed and responds accordingly.
Unlike TMCC, DCS locomotives receive commands through the track .
