Helixology for N scalers - Model Railroader - Trains
2023年3月7日 · Helixes with the smaller radii used in N scale have tight grade separation, leaving little room for hands – or for error. Jim Kelly’s 18 3⁄4″ radius helix, seen here, has a 2.2 percent grade, and barely clears his tallest rolling stock.

Every helix, is slightly larger than the radius of the outermost track on the helix. For example, our 15" single track helix requires a minimum footprint of 33" x 33". Check out our table of minimum space requirements: N Scale 1 track helix minimum space requirements. N Scale 2 track helix minimum space requirements. Double Check Your Helix ...

I am considering using a small helix on an N scale layout. I have seen a couple on the web recently, but no real details of how they were built. I designed one about 15-20 years ago which was realised in 1/2" ply, but that seems like something of an overengineering exercise.
