Gradient in railway
In steam days Southern Pacific trains eastward across Nevada and Utah faced nothing steeper than 0.43% in the 531 miles from Sparks to Ogden—except for a few miles of 1.4% east of Wells. Trains would leave Sparks with enough engine to manage the 0.43% grade (e.g. a 2-10-2 with a 5500-ton train) and would get helper engines at Wells; the "ruling grade" from Sparks to Ogden could be considered 0.43%. But nowadays the railroad doesn't base helper engines at Wells so trains m… WebThe 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.

Ruling gradient • … WebTrack gauge or rail gauge (also known as track gage in the United States) is the distance between the inner sides (gauge sides) of the heads of the two load bearing rails that make up a single railway line. Each country uses different gauges for different types of trains. However, the 1,435 mm (4 ft 8 + 1 ⁄ 2 in) gauge is the basis of 60% of the world's railways.
WebA particular section of this railway makes extremes detours with multiple viaducs and tunnels (including a circular tunnel) in order to climb 231m while having a gradient of only 1%. According to the museum's explanation, the gradient of 1% was required because they wanted to allow heavy military freight trains to circulate on this railway.
