Cant (road and rail)

For other uses, see Cant (disambiguation).

The cant of a railway track or camber of a road (also referred to as superelevation, cross slope, cross fall, or difference in crosslevel) is the difference in elevation (height) between the two rails or edges of the road. This is normally greater where the railway or road is curved; raising the outer rail or the outer edge of the road creates a banked turn, thus allowing vehicles to travel round the curve at greater speeds than would be possible if the surface were level.
