Reply to "TMCC lock on a circuit breaker protector"

You cannot hook the bridge and command base together to the Legacy base. The Cab1 and Cab2 live together nicely as long as there is no TMCC base involved. That means all controls and commands are available with the cab2 and only conventional TR commands on the cab1(conventional track varied voltage, whistle and bell). That's the way I had it hooked up if I remember correctly.
