An inclination from a horizontal or vertical line; a slope or bevel; a titl.
Amount by which one rail of a curved track is raised above the other. Cant is 'positive' when the outer rail is higher than the inner rail and 'negative' when the inner rail is higher than the outer. Also known as "super elevation".
heel over; "The tower is tilting"; "The ceiling is slanting"
Curved track usually has the outer rail raised slightly above the inner one (superelevated) to tilt the centre of gravity of the train inwards. This reduces the lateral forces experienced by passengers and improves the stability of the train when passing through curves at speed. See Cant (Superelevation)
The inward inclination of a rail, effected by the use of inclined surface tie plates, expressed as a rate of inclination, such as 1 in 40.
Bevel or chamfer, as on an edge.
The cant of a road (sometimes referred to as camber) or railway (also referred to as superelevation) is the difference in elevation of the two edges; a cant which is not equal to zero results in a banked turn, allowing vehicles traveling through the turn to go at higher speeds than would normally be possible.
