Geometric design of railway
WebGeometric design should be such as to provide maximum efficiency in the traffic operation with maximum safety at reasonable cost. Gradient Any departure of track … 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, construction and maintenance of track. Track geometry involves standards, speed limits and other … See more Horizontal layout Horizontal layout is the track layout on the horizontal plane. This can be thought of as the plan view which is a view of a 3-dimensional track from the position above the track. In track … 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 lower to prevent an outward horizontal centrifugal force to overturn the trains … See more • Geometric design of roads • Jim crow, a tool for bending rails • Track geometry car See more 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 … See more Track gradient The term track gradient is relative elevation of the two rails along the track. This can be expressed in the distance traveled … See more The term alignment is used in both horizontal and vertical layouts to describe the line uniformity (straightness) of the rails. The horizontal alignment (or alinement in the United States) is done by using a predefined length … See more
