I have used the v16 Kato set in several of my recent layouts. This variation is the largest radius double track set from Kato. It fits nicely on a four foot wide table.
This week I added turnouts on all four inside corners and a crossover in the center. With this configuration, a train can do a reverse loop from any direction, without going in reverse.
To simplify operation, I used three power supplies. One power supply feeds each outside loop and a separate power supply feeds the two crossover tracks in the middle. Each of the two crossover sections has a feeder track. I oriented the feeder tracks so that trains entering the crossover from the right would be “forward” and trains entering from the left would be “reverse” on the power supply.
You can see all the switching going on in the video. In about two minutes, all three trains were reversed in direction. This simple layout is a lot of fun to use. SCARM file is available for download.
