I have noticed some of my steam locomotives headlights have been flashing and have not been responsive to commands sent either from the the Cab1 or Legacy Cab2 controller. This problem was for the entire layout. When I placed my hand on the handrails (antenna) for the locomotive the flashing stopped. From reading other posts about this problem I went about making sure the track and pickup rollers were clean and attaching a wire to the main water pipe and running it between the two parallel tracks. No change, headlight still flashed. I then disconnected the legacy base from the layout and left the original TMCC Base connected. Flashing stopped an locomotive operated normally. I then disconnected the TMCC Base and reattached the Legacy Base and the flashing stopped and the locomotive operated normally. I checked the connecting cables and all were correctly connected and all connections were snug. Both power supplies are connected to the same power strip. The power strip is connected to a well grounded outlet.
Any thoughts on why these two bases are not in sync would be appreciated.
