I have a large layout and it currently uses one TIU channel/one throttle per loop (Z4k tracks feed fixed TIU channels, fixed power feeds variable channels). Because I have extra TIU channels and throttles available, I am considering breaking each loop into 2 power districts. If each power district has its own TIU channel and throttle, how do you coordinate the voltage when running conventional trains? Is it possible to adjust both throttles simultaneously as if they were one? Running in command mode seems straightforward, not clear how easy it will be running conventional.
Thanks!
