The On30 Pacific Coast Air Line was a 4 x 8 railroad based on the On30 railroad trackplan in the "2002 Model Railroad Planning" by Kalmbach Publishing. The major feature of the On30 track plan was the adaptation of the loads in/out. The spur was set up as a rock quarry to a rock crusher like the rock crusher in the November/December 1957 Model Railroader.
We are now modeling the railroad in the late 1880's using 55n3 in a larger format. It is based on the Pacific Coast Railway.
