heritage railway | A railway track blog

The running of the trains over the railway track is inducing vertical and lateral forces that, in time, are affecting the track alignment, changing incrementally the installed track and causing track irregularities. On curved track this deterioration process is more significant due to the additional effect of the lateral (centrifugal) acceleration.

Track grades | Model Railroad Hobbyist magazine

Grade equivalent curve is defined as the equivalent grade that is equal to the drag the train gets from a curve. Prototype railroads have a complicated formula for this, but a good rule of thumb for HO is 32/ radius of the curve. So a 64 inch radius curve is the equivalent of a 1/2 percent grade. But a 18 inch curve has the grade equivalent of 2%.
