Abstract
A system and method for inspecting a railway track. The system preferably includes: a processor; at least one sensor oriented to capture data of the railway track; a data storage device in electronic communication with the processor; and computer executable instructions stored on a computer readable storage medium in communication with the processor operable to: determine an elevation of a surface of a rail head of a rail located on the railway track based on a distance to the rail head from the at least one sensor, determine an elevation of a surface of a crosstie of the railway track based on a distance to a top surface of the crosstie from the at least one sensor, estimate a total rail height and underlying rail support, and calculate a crosstie wear value based on the determined rail head surface elevation, crosstie surface elevation, and estimated total rail height and underlying rail support.
