Sometime the cant is measured in term of angle instead of height difference. [12] In North America, it is measured in height difference and called crosslevel, even for the curved track. When the outside rail is at higher elevation than the inside rail, it is called positive cant. This is normally the desired layout for curved track.
Cant in a velodrome. The cant of a railway track or camber of a road (also referred to as superelevation, cross slope or cross fall) is the rate of change in elevation (height) between the two rails or edges of the road.
On a mixed traffic route owned by a freight rail company, freight considerations are likely to prevail. On a mixed traffic route owned by a passenger rail company some kind of compromise may be needed. Cant deficiency is generally looked at with respect to ideal track geometry. As geometry of real track is never perfect it may be desirable to ...
A right-hand railroad switch with point indicator pointing to right Animated diagram of a right-hand railroad switch. Rail track A divides into two: track B (the straight track) and track C (the diverging track); note that the green line represents direction of travel only, the black lines represent fixed portions of track, and the red lines depict the moving components.
Here grade refers to the tangent of the angle of rise of the track. The design pattern for horizontal geometry is typically a sequence of straight line (i.e., a tangent) and curve (i.e. a circular arc) segments connected by transition curves.
Gooseneck: The vertical handrail that joins a sloped handrail to a higher handrail on the balcony or landing is a gooseneck. Rosette: Where the handrail ends in the wall and a half-newel is not used, it may be trimmed by a rosette. Easings: Wall handrails are mounted directly onto the wall with wall brackets. At the bottom of the stairs, such ...
