Question

Write down the geometric requirements of high speed track

Answer 1

True high-speed rail, in excess of 125 mph, requires dedicated electrified passenger tracks that are grade separated from roads and other rails. The speed at which a train can travel is limited by the type of track it travels on. Modern trains can travel seamlessly from conventional track to high-speed track.

Track geometry is three-dimensional geometry of track layouts and associated measurements used in design, construction and maintenance of railroad tracks. The subject is used in the context of standards, speed limits and other regulations in the areas of track gauge, alignment, elevation, curvature and track surface.
