Minimum railway curve radius

90-foot (27.43 m) radii on the elevated 1,435 mm (4 ft 8 1⁄2 in) Chicago 'L'. There is no room for longer radii at this street intersection

The minimum railway curve radius, the shortest allowable design radius for railway tracks under a particular set of conditions. It has an important bearing on constructions costs and operating costs and, in combination with superelevation (difference in elevation of the two rails) in the case of train tracks, determines the maximum safe speed of a curve. Minimum radius of curve is one parameter in the design of railway vehicles as well as trams. Monorails and guideways are also subject to minimum radii.
