Here is some more information based on your questions:
- According to Lionel: "Both units powered with lights and smoke".
- "RailSounds in lead A unit" - Good catch Marty; no sound in Unit B.
- It doesn't respond to ID 1 but with ID 99 I can drive both units at the same time (B unit IS motorized; running on parallel track) with smoke being produced by both units.
- I haven't been able to identify any working lights on the B unit
- Tried programming in Run mode; no change
- Cab-3 app roster doesn't list the B unit (doesn't list SuperBass E6B either).
