Several shots of me building a concentric helix with splines of masonite.
I wanted a smooth climb that I can pull longer trains. This helix only requires the track to pass under itself once, at the bottom. I will have 4 occupancy detectors to show location of trains traveling through this helix with LEDs.Loops: 6
Radius – Bottom: 38″ Top: 57″
Rise: 12″
Slope: 1.0%
Gain between turns: +/- 2″ScottyB, Steve-The-British-Railroader and 5 others-
