The present disclosure provides, as a sleeper pad for railroad sleepers in which a nonwoven fabric is attached to a rubber pad by a thermal fusion process, a nonwoven fabric-integrated sleeper pad using a rubber pad embedded with a stiffener and methods of manufacturing and constructing the same, which can adjust vertical support stiffness of the rubber pad by the stiffener embedded in the middle of the rubber pad and which can secure the flatness of the rubber pad by resisting bending deformation due to a difference in shrinkage between rubber and nonwoven fabric.

A turnout arrangement of a slab track with a ballastless superstructure for forming a main track (1) and a branch track (2) which branches off from the main track for railway traffic has a plurality of prefabricated turnout bases (3) of untensioned reinforced concrete, a casting compound (5), which is cast and hardened between the aligned turnout bases and the ground (4), a plurality of fastening areas (6) which are rail support points (7) provided on the turnout bases for the rail fastening of the main track, the branch track, and further turnout components. The turnout bases of the turnout arrangement are elastically supported, and each turnout base is provided with a positive-locking arrangement for positively holding the turnout base horizontally with respect to the casting compound. An elastic layer (8) is provided between a projection (13) of an element of the positive-locking arrangement and the turnout base.

An under sleeper pad (1) to be fastened to an underside (3) of a sleeper (4), on the opposite side from the tracks (2). The under sleeper pad (1) has at least one elastic layer (5) having cork grains (6) of a cork granulate distributed throughout. In addition, the elastic layer (5) has at least one cellular synthetic elastomer (7).

A fastening system for fastening a rail for rolling stocks such as trains, including a base plate, an elastic material and a rigid casing, wherein the base plate is embedded in the elastic material and the elastic material is arranged, at least partially, between the base plate and the rigid casing.

A rail tie pad for use with a cast rail tie. The rail tie pad may be flexible, polymeric body having first and second opposite sides and, when viewed in cross-section, includes an upper surface and a lower surface defining a first vertical thickness and including a plurality of undulations with alternating concave portions and convex portions. The rail tie pad further includes a pair of side anchor portions respectively disposed at the first and second opposite sides of the pad, each including at least one anchor projection for embedment within the side portions of a cast rail tie. In this manner, the anchor portions of the rail tie pad are embedded within, and fixably secure, the sides of the rail tie pad to the cast rail tie to mitigate or prevent separation of the rail tie pad from the rail tie during transport and/or positioning of the rail tie during installation.

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.

The invention relates to a sleeper pad (1) for fastening to at least one outer surface (3) of a railway sleeper (4) facing a ballast bed (2), the sleeper pad (1) including or consisting of at least one damping layer (5), wherein the damping layer (5) has an EPM index in the range from 10 to 25%, preferably in the range from 10 to 20% when carrying out a load test.

An under sleeper pad (1) for fastening to an outer surface (2) facing a ballast bed (16), in particular an underside, of a railroad sleeper (3). The under sleeper pad (1) includes an elastomer layer (5), the elastomer layer (5) having a density in the range of 250 kg/m.sup.3 to 350 kg/m.sup.3, preferably 250 kg/m.sup.3 to 330 kg/m.sup.3.

A special trackwork assembly including a special trackwork body formed to support wheels of a train moving over a running surface portion of an exterior surface of the special trackwork body that generate traffic-related vibrations of the special trackwork body having one or more frequencies of interest. The special trackwork assembly also includes one or more tuned mass dampers secured to the special trackwork body and formed to vibrate, in response to the traffic-related vibrations of the special trackwork body, at the frequency of interest, to at least partially dampen the traffic-related vibrations of the special trackwork body.

A vibration dampening boot for railway tie blocks and a method of manufacturing railway tie block assemblies. The boot includes a bottom wall with resilient tie block contact structures disposed at different heights for initial tie block support and variable vibration dampening. The upper portion of the boot terminates in a removable wall connected to the side walls of the boot by a relatively thin tear strip to enable direct pouring of cast material, such as concrete or epoxy, into the boot for casting the tie block, with the wall removable after installation of the tie block assembly into a railway bed. In this manner, the boot may be used with pre-cast tie blocks as well as accommodate direct casting of the tie blocks within the boot to form a tie block assembly.
