Returning to modelling after a very long lay off and I'm keen to restart with DCC. Planned layout is from Freezers 1971 60 plans for small railways and consists of a single circuit with passing loops at a through station with a terminus heading off from one corner at a triancular juction which basically forms an out and back circuit or continuous run. Basically it looks to me that the whole circuit becomes a reversing loop. How does this work in practice? Any help much appreciated...
