An example method for forming a track system includes: providing track ties configured to support rails; providing stone ballast configured to support the track ties; and disposing a layer of rubberized asphalt coating between the ballast and the track ties, the rubberized asphalt coating having a bituminous binder, crumb rubber particles, and small gradation stone 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 the bottom of the tie and to each other while inhibiting abrasion of adjacent ones of the particles of the ballast against each other and against the bottom of the track ties.

This cross-member system with shell (10) for a railroad track, intended to be wedged in an apron of the railroad track, of the type including a cross-member (12) having a lower face (20), and an upper face (22) that is intended to receive a rail fastening system (14), and a shell, is characterized in that the shell envelops substantially the entire cross-member so as to define an inner volume for receiving the cross-member that is sealed against outside attacks.

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 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.
