An example track system includes: a supporting structure; ballast supported by the supporting structure; a plurality of track ties supported by the ballast; a pair of rails supported by the plurality of track ties; and a layer of rubberized asphalt coating disposed as an interface between the ballast and the supporting structure, the rubberized asphalt coating having bituminous binder, crumb rubber particles, and small gradation hard rock aggregate; wherein resiliency of the layer of rubberized asphalt coating permits particles of the ballast in direct contact with the layer of rubberized asphalt coating to move elastically relative to each other while inhibiting abrasion of adjacent ones of the particles of the ballast against each other and against the supporting structure.

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 with at least one cross-sectional rib and a top load transfer element with at least one longitudinal vertical fin, 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 vertical load transfer element comprises a plurality of cross-sectional ribs spaced along a length of the vertical load transfer element. In another embodiment, the top load transfer element comprises a plurality of longitudinal vertical fins spaced along a perimeter of the top load transfer element to enhance stability of the top load transfer element.

A method for producing a structure, comprising providing a Composite Conductive Substrate (CCS) with a conductive layer, a non-conductive layer and a release layer, implemented on top of the conductive layer; determining an empty conductive pattern for each layer of the structure; printing a layer of non-conductive matter on the CCS, such that the conductive pattern of the first layer left empty from the non-conductive matter; on top of the release layer, below which the conductive layer is implemented, filling the empty conductive pattern with conductive matter by electroplating; peeling the filled conductive matter or peeling the filled conductive matter and the printed non-conductive matter, from the conductive layer of the CCS.

A track beam includes a main component and a guide component. The main component includes a top plate, a bottom plate, and a web plate. The bottom plate is disposed below the top plate, and the web plate is connected between the top plate and the bottom plate. The guide component includes a guide plate and a connecting structure. The guide plate is disposed between the top plate and the bottom plate. The guide plate includes a planar plate structure extending in a longitudinal direction and is spaced apart from the web plate in a transverse direction. The connecting structure is connected between the main component and the guide plate such that the guide plate is connected to the main component through the connecting structure.

A fastening system for track rail includes a molded support block, and a direct fixation fastener positioned upon an upper side of the molded support block. The direct fixation fastener includes a metallic frame and a non-metallic overmolded jacket. Clamping fasteners of the fastening system are structured to engage with retention elements integrally molded in a concrete matrix material of the molded support block to clamp the direct fixation fastener to the upper side within a range of lateral positions.

A method is provided for foaming a ballast bed of a railway track wherein the railway track comprises sleepers positioned on the ballast bed and rails positioned on the sleepers, wherein the rails are covered at least in a partial area along a region of the ballast bed to be foamed, and a foaming agent is introduced into the ballast bed while the rails are covered, wherein the ballast bed has in a sleeper bay defined by two successive sleepers an upper side facing against the gravitational direction, and the ballast bed is heaped up so that the upper side of the ballast bed reaches at least up to an underneath side of the sleeper facing in the gravitational direction.

A ground stabilisation system is used for stabilising a subgrade region which includes a peat layer under a railway having rails supported across rail ties on a ballast layer over the subgrade region. The system uses a plurality of drain members submerged in an upright orientation within the peat layer of the subgrade region in which each drain member has a hollow interior and a plurality of openings therein which allow communication of fluid from the peat layer surrounding the drain member into the hollow interior of the drain member so as to be arranged to reduce fluid pressure in the peat layer when the peat layer undergoes dynamic loading from a passing train. Each drain member is a semi-rigid pipe having an axial stiffness greater than a dynamic stiffness of the peat layer to reduce loading on the peat layer under dynamic loading from a passing train.

This method makes it possible to characterize the seat of a railroad track through penetrometric and geo-endoscopic tests. It includes steps consisting of striking ram head of a light dynamic penetrometer to drive the tip of a train of rods into the seat, measuring the strength of the seat as a function of the pushing in depth of the train of rods, removing the train of rods from the seat, pushing a tube into a hole left by the train of rods, and sliding an image-recording camera inside the tube. The method includes additional automated steps consisting of measuring the position of the camera while it slides inside the tube, i.e., the dep that which the images are recorded, and couplingan analysis of the recorded images as a function of the depth with the strength measurements of the seat to characterize the different layers of the seat.
