Abstract

Track irregularities can cause deterioation of riding comfort and derailment.Track gauge variation is one of the basic track irregularities. Track Recording Car is an automated track inspection vehicle on a rail transport system used to test several geometric parameters of the track. Track geomeotry parameters generally measured include position, speed, gauge, alignment, crosslevel, curvature and so on. This paper presents a novel technique for the measurement of track gauge variation, a new measurement system was introduced and been in assembled on a new type underground track recoring car.
