Abstract:

A method for delivering ballast to a section of railroad track includes measuring an existing ballast profile of a section of railroad track using a remote sensing system, and providing a signal indicative thereof to a first computer. Using the first computer, the existing ballast profile is compared with an ideal ballast profile to compute a track file representing a volume of additional ballast needed as a function of linear position along the section of railroad track, and data representing the track file is transmitted to a second computer of an automatic ballast dump train. Ballast is dumped along the section of railroad track according to the track file under control of the second computer.

Abstract:

A method, performed by a computer having a processor and system memory, for calibrating a tie height of a ballast profiling rail vehicle having a remote sensing system, includes traversing the rail vehicle along a first calibration section of railroad track at a calibration speed, detecting, using the remote sensing system, a plurality of height to tie measurements in the first calibration section, establishing a rolling median average of the height to tie measurements, and determining a calibration tie height relative to the rail vehicle based upon the rolling median average.
