HI , I was wondering if many people used the concept of " block switching" for DC wiring, which seem more common in the US. This where the layout is divided into electrical blocks and each block ( and its corresponding trackwork ) and then switch to an appropriate controller.
The advantages are the removal of the issues of synchronising controllers when running trains from one track controlled by a controller to another, as is common with the more conventional " isolating sections" , form of wiring we then to do on this side of the pond
I have used blocks for permanent layouts for years, effectively "Cab Control" so you can drive a train anywhere on the layout from one controller, Using rotary 2 pole 6 way or 3 pole 4 way switches from Maplin any section can be fed from any one of 4 controllers and as soon as the loco is clear the section can be switched to another controller.
You can also switch everything off one bit at a time when faults arise, which is a very good reason for using sections even if you use DCC. Without this facility fault finding can literally take hours and involve snipping wires to disconnect bus bars etc, Nightmare,
One controller permanently feeding one section of tracks and further controllers feeding other tracks is rather inflexible, works ok for starter layouts with set track but getting locos from one controller to another can cause issues.
