An apparatus for applying a single-component or multi-component adhesive to a ballast bed of a stretch of rails in a rail path, includes a container for the adhesive and elements for conveying the adhesive for application are mounted on a supply vehicle which can be driven on, or adjacent to, the rail path. The adhesive is guided from the supply vehicle with a hose having a one nozzle. The apparatus further includes a trolley that can be temporarily coupled and secured to a rail, and can be moved in a rail-bound manner at a desired and uniform speed independently of the supply vehicle. The trolley supports a boom on which the nozzle is mounted, so that a defined depth of penetration of the adhesive can be maintained by the apparatus at a uniform running speed of the trolley and defined flow rates of the adhesive depending upon the characteristics of the ballast bed and spray pattern.

A system for and method of stabilizing rail track structures using a load transfer apparatus is disclosed. The load transfer apparatus includes a vertical load transfer element and a top load transfer element, wherein the top load transfer element is used to transfer applied locomotive and rail car loads to the vertical load transfer element. In one embodiment, the top load transfer element includes helical flights. In another embodiment, the top load transfer element includes a flared top. In yet another embodiment, the top load transfer element includes a load transfer cap. In a further embodiment, the top load transfer element includes two or more support legs each with a top support attached thereto. The railroad stabilization system can comprise any one type or any combinations of types of the aforementioned load transfer apparatuses.

Disclosed is a rail supporting assembly for supporting a contact rail of a railway system that includes a base, a rail support head positioned relative to the base, and a support member comprising a dielectric phenolic material coupled to and positioned between the rail support head and the base to thereby support and insulate the contact rail. The support member preferably is coated with a varnish to prevent absorption of water by the support member.

A method and apparatus for coating transportation components such as a bridge deck with a coating. The coating includes a sealant and rubber mixed with a resin and a foaming agent. The apparatus includes a hopper for the rubber, a impingement gun for the resin and a gun assembly that combines the rubber and resin together at a combined nozzle for spraying.

The invention is a system and method for repairing, improving, and stabilizing subgrade and subsoil/natural ground layers of a rail bed generally consisting of softer soils. One embodiment includes a method of installing subsurface inclusions and ballast fills comprising injected slurry mixtures of stabilizing material such as cement grout mixed with in situ soil. Another embodiment includes a system of installed ground inclusions and ballast fills. Another embodiment includes an integrated system of equipment for emplacing the system of inclusions and ballast fills.

A protective coating system for a railway structure having a waterproof membrane and a ballast mat. The waterproof membrane is disposed on the railway structure. The ballast mat further has a ballast protection coating and a sealing layer. The ballast protection coating is a rubber compound and is disposed on the waterproof membrane. The sealing layer is disposed on the ballast protection layer.

An apparatus for discharging multi-component adhesives of at least two fluidic components onto a granular ballast bed of a railway rail train includes of at least two separate carriages, which can be transferred into a vehicle or a trailer by having the vehicle or the trailer equipped on the inside with rails onto which the carriages can be rolled. The wagons can thus be transported by road to the usage site and can be put into operation by placing them from the trailer onto the tracks of the railway track using extendable rails. The apparatus allows the fully automatic spreading of adhesives over long distances to a ballast bed, so that the ballast bed is bonded in so that trains can continue to run normally. The entire apparatus can be loaded, transported and unloaded on site and put into operation by just two persons.

A track maintenance machine, constructed to be mobile on a track, for consolidation of a ballast bed underneath a track, includes a machine frame supported on an undercarriage and a consolidating device, connected to the machine frame, which includes at least one consolidating element constructed to be lowered. The consolidating element is constructed as a consolidating plate which, in a working position, is larger in a longitudinal direction of the track than a distance between two sleepers of the track, and the consolidating plate is disposed to be rotatable in order to turn the consolidating plate into a passing position for lowering or raising between two sleepers. A method for consolidation of the ballast bed underneath a track by using a track maintenance machine is also provided.

A hand-held tamper for underfilling ballast of a track. The tamper has a drive motor for the rotation of an unbalance and a tamping shovel fastened to a lower end of a shaft which is joined to the drive motor and has a longitudinal axis. The shovel consists of two shovel halves each joined to the shaft. Each shovel half has an upper shovel part nearer to the drive motor and a lower shovel part positioned at a first angle <180 in relation thereto. Both shovel halves are disposed at a second angle <180 relative to one another when viewed in the direction of the longitudinal axis of the shaft.

By supporting a space generated by a settlement of the track bed gravel or asphalt roadbed underneath a concrete rail tie with cylindrical rods, and installing the present invention, one each separately, on the left and right sides of the concrete rail tie, recovery from settlements is automatic, and the response to differential settlements of the left and right rails of the track due to the train load can be easily facilitated, and by installing pressure reducing valves on the upper part of the concrete rail ties, pressure can be reduced while maintaining the track system as is without having to dismantle the concrete rail ties, and accordingly the usability of the concrete rail ties can be improved.
