Our CLUB Layout ca be controlled By TMCC & LEGACY. Saturday Morning I tested the Legacy Control and it functioned properly! Went to Lunch and when I returned it wasn't! Found three Junior Members trying to use the System to run their Legacy Engines. When they handed the CAB2 to me , this is what was happening. When you Turned the Velocity Knob (Speed Control Knob), the graph on the CAB2 wouldn't move either way. The only way we could get the Engine to run was using the "Preset" Speeds, ie 5, 20, 35, etc. mph buttons. Turned off the Base and CAB2 & turned them back on, NO change. YES, the Train Brake was turned all the way down!!! The Graph moved with the different Speed Icons only. Also if you tried to Scroll thru the different Engine, that didn't work as well. I assumed it was the CAB2, so brought it home to test on my LEGACY Layout! GUESS WHAT; no problem what so ever with the CAB2 . I don't know what those Kids did to screw up that Base Unit. Unfortunately I live 60 Miles away from our Club, so can't do anymore testing (with the Base) until next Saturday.
