GM: All the better DCC systems have built in circuit breakers. My Lenz 100 syetem works instantaneously if a short circuit develops. The entire system shuts down. You don't need a circuit breaker in an auto reversing unit. Post your questions. If I can answer them I will. Stay cool and run steam....
Bob, Although I didn't show them on the preliminary Electrical Plan, it will probably be necessary to allow for connection of more throttles to the throttle bus. Unless a lot of people have Digitrax UT4R type throttles. The question is how many people can reasonably be expected to operate a model railroad of this magnitude. I can foresee maybe as many as 4. Beyond that, I think that they would just get in each other’s way. GM
