My experience, my latest layout is small, about 50’ of total mainline run, about 100’ of total track, I wired it using the method for DCC, with main bus and feeder wires, but also divided it into blocks, with both rails insulated, and added the feeders accordingly. My previous layout used blocks and cab control, so I used the Atlas controlers left over from this layout. I started out using DC, but as I added more DCC locos, either factory or wired with decoders, I eventually have gone over to using DCC only. The locos I have that are not DCC, have been wired with the harness and dummy plugs, so I run them on DCC.
What I like, and use, with the DCC, is the ability to have a train on the main, running, and still being able to switch the yard and industries. I even bring the switcher out on the main, while moving cars, and get it done and out of the way, in time for the main line train to pass. I think this is the coolest part, and to be able to have a local follow the main line train, to the siding, for switching industries. It’s just totally awesome to be able to run multiple locos, without the hassle of using cab control.
I use the Digitrax Super Empire Builder, with the DT400 throttle, and the DP150. I’m the only operator, and as of yet, not involved with any club, although I would like to explore that option, and try an “operating session” on a club layout. My layout is not big enough for anything like that.
Good luck in your choice.
Mike.
