Track 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) … See more Track geometry is concerned with the properties and relations of points, lines, curves, and surfaces in the three-dimensional positioning of railroad track. The term is also applied to measurements used in design, … See more Crosslevel Crosslevel (or 'cross level') is the measurement of the difference in elevation (height) between the top surface of the two rails at any point of railroad track. The two points (each at the head of each rail) are measured at by the … See more In most countries, the measurement of curvature of curved track is expressed in radius. The shorter the radius, the sharper the curve is. For sharper curves, the speed limits are … See more • Geometric design of roads • Jim crow, a tool for bending rails • Track geometry car See more Horizontal layout Horizontal layout is the track layout on the horizontal plane.
