An annual inspection of rail geometry is necessary to ensure proper track position, curvature alignment, smoothness, cross level, and other factors for safe an efficient train movement.
And to test several geometric parameters of the track without obstructing normal revenue operations. Some of the parameters generally measured include position, curvature, alignment of the track, smoothness, and the cross level of the rails. The testing vehicle will use a variety of sensors, measuring systems, and data management systems to create a profile of the track being inspected. The Track Geometry Vehicle must be able to collect track geometry measurements that include gauge, curvature, cross level, super elevation, 31’ and 62’ warp, 31’ and 62’ twist, track alignment and rail profiles of both left and right running rails though an automated data collection system.
