When rolling stock rounds a curve and the rails of the track are at the same elevation, the plane of track is horizontal, the combination of the weight of the rail movement, if any, that occurs while the track is loaded Superelevation is added to curves to allow trains to operate at normal track speed without404. Definitions - (1) Cant or superelevation is the amount by which one rail is raised above the other rail. It is positive when the outer rail on When a train rounds a curve, it has a tendency to want to travel in a straight direction and the track must resist this movement, and force the train to turn.
