APPARATUS AND METHOD FOR CALCULATING CROSSTIE PLATE CUT AND RAIL SEAT ABRASION BASED ON RAIL HEAD HEIGHT
A method and a system for inspecting a railway track are provided. The method comprises the determination of an elevation of a surface of a rail head based on a distance to the rail head from the at least one sensor. An elevation of a surface of a crosstie of the railway track is determined based on a distance to a top surface of the crosstie from the at least one sensor.
