Updates: The Locomotive is a Lionel H-7 Class 2-8-8-2 Steam Locomotive and Tender featuring Trainmaster Control. Concerning the Antennas, I checked the ends & wire, everything looks in order. I tried everything in the manual to install Trainmaster Command to no avail and would not Reset. I tried to reinstall Legacy Cab-1L Command. Note, It worked on my layout, Legacy Base 6-37156 & Controller 6-37155. Museum, Legacy Base 6-36156 & Controller 6-37155 should have worked. Their Trainmaster Command is Model Base -1 & Controller Cab-1.
The manual says, "To operate in Command mode, you need a Command Base(6-12911 and a Cab-1 Remote Controller (6-12868)." the above Legacy Base & Controllers are updated versions and should have worked.
There has to be another way too Reset to Factory commands. I think this would solve the problems.
