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.

Abstract: A system and method for adjusting light emitter output for a railway track inspection system based on data feedback from one or more sensors. The system includes: a power source; a light emitting apparatus emitting light energy toward a railway track; a 3D sensor acquiring three-dimensional data of the railway track; a shaft encoder emitting pulses at a rate that corresponds to a speed of the railway track vehicle; and an algorithm operable on processor to: analyze the three-dimensional data from the 3D sensor; receive pulses from the shaft encoder; and adjust a light emitter control output value based on the analyzed three-dimensional data and the received pulses. A controller in communication with the processor is configured to control the light intensity of the light emitting apparatus in response to the light emitter control output value.
