Abstract: Systems and methods for automated repair and maintenance operations on a railroad track comprise a work head that is automatically moved over the railroad track according to a predetermined pattern, such as the movement of an applicator for tie plugging compound according to a predetermined pattern of spike holes. The automated repair and maintenance operations may be coupled to systems and methods for automatically detecting a feature on a railroad track that comprise two or more distance measurement sensors that travel over the railroad track. Features on the railroad track are detected where the distance measured by each sensor falls within two different predetermined distance ranges.

Abstract: A method for repair and preventive maintenance of railroad ties by application of a polymer system to the surface of the rail seat. The polymer system is cured by irradiation with ultraviolet light to fully cure or partially cure the polymer. The polymer system may be used in conjunction with a tie pad that is capable of transmitting ultraviolet light to permit curing of the polymer.
