Disclosed are different embodiments of a railway tie assembly for securing a rail along a railway track. In one embodiment, the assembly comprises a plurality of composite polymer crossties fabricated from a composition comprising an asphaltic component, a polymeric composition component and a strengthening agent; and a pair of rail clips for securing the rail across each of said composite polymer crossties, wherein each of the rail clips comprises a rail-engagement portion configured to engage a corresponding railseat, and an anchoring portion to be anchored to a given crosstie and cooperate with the rail-engagement portion to secure the corresponding railseat against a load-bearing surface of the given crosstie.

A laminated wood and encapsulated railroad tie structure and its associated method of manufacture. A wood core of laminated wood slats is inserted into an extruded sleeve of scrap tire rubber and polyurethane. A urethane adhesive laminates the wood slats together and serves as a lubricant and bonding agent for placement and secured engagement of the sleeve about the core. End caps are securely engaged at each end of the composite sleeve, being secured to both the wood or other natural fiber core and sleeve. Longitudinal grooves or slots for engagement with a railroad bed characterize the bottom and side surfaces of the sleeve. The core may be provided with bores and grooves to receive sensors and conductors interconnected with a processor and transponder maintained in an end cap. The end case also maintains a photovoltaic device and power source for the active elements of the railroad tie structure. The core may also be manufactured of a wood or other natural fiber giving the core a desired flex modulus to provide for better control and serviceability of associated rails and railway cars.

The present disclosure provides for an automated spray system (100) to produce an elastomeric pad on a railroad tie. The automated spray system (100) includes a two-component spray system (102) for spraying a two-component reaction mixture to produce the elastomeric pad on the railroad tie. The automated spray system further includes a gantry system (140) having girder (146) that supports the spray applicator.

A railroad sleeper (1) for fixation of at least a pair of rails (2,2) of a railroad network is provided, including a contact surface (3), wherein each rail of the pair of rails (2,2) is fixed spaced apart from each other, the railroad sleeper (1) being configured by including a hollow sector (4) delimited by association of the contact surface (3) with the anchorage walls (5,5), thus establishing a free portion (17) adjacent to the anchorage walls (5,5) and opposite the contact surface (3). An embodiment in which the hollow sector (4) of the railroad sleeper is delimited by a support surface and the process of manufacturing a railroad sleeper is also provided.

An enhanced wood product includes a urea coating to increase the strength of the wood product and various products made with coated wood.

An extruded PVC railroad tie with glass fiber reinforcement contains glass fibers and clumps of pelletized glass fibers that enhance friction of all surfaces that are not coated with a cap stock. Parallel spaced apart interior walls enhance structural integrity. Two interior walls provide structures for threaded channels to threadedly and frictionally engage bolts for securing rail connection hardware. Interior compartments provide empty space for air and ballast. Air in the compartments moderates thermal expansion. A protective cap stock covers one or more sides, such as the exterior top and side surfaces of the tie. The bottom surface, which may be substantially devoid of a cap stock, exhibits roughness to grip and frictionally engage underlying ballast.
