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.

• E01B 31/26 - Inserting or removing inserts or fillings for holes in sleepers, e.g. plugs, sleeves
• B05B 13/06 - Machines or plants for applying liquids or other fluent materials to surfaces of objects or other work by spraying, not covered by groups specially designed for treating the inside of hollow bodies

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.

Abstract

A method for construction of a concrete platform for use in slab track railroads, comprising supporting a tie plate and rail on a concrete form for casting the concrete platform. The concrete form includes a horizontal form positioned below the tie plate, that supports a cast in place fastener system that is imbedded in the surface of the concrete platform and secures the tie plate to the concrete platform. The horizontal form comprises a removable or sacrificial insert that is cast into the surface of the concrete platform. Materials such as expanded polystyrene can be used to make sacrificial inserts that can be removed by dissolving with solvents such as dibasic esters. After the concrete platform is cast, the removable insert is removed and the resulting cavity is filled with a filler material, all without the need to disassemble the tie plate and rail.

Abstract

A tie plate handling device for use in connection with removing and replacing railroad tie plates from a track during a rail change-out process. The tie plate handling device provides operator lift assistance and certain embodiments provide for a fully automated lift and movement of railroad tie plates. The tie plate handling device comprises a lifting arm, an engaging unit for securely coupling with a tie plate and a control unit for operating the same. Methods for using the tie plate handling device in conjunction with the rail change-out process are also described.

Abstract

A remedial railroad tie repair treatment capable of extending the useful life of a railroad tie. The remedial repair treatment comprises a mixture of a borate solution and a chemical tie plugging compound combined that, when applied to a wooden area of interest, will delay the decay thereof and facilitate penetration of the borate through the wood fibers. The remedial repair treatment may alternatively comprise sequential application of the borate solution and the plugging compound to the wooden area of interest.
