A grooved rail switch device (10) having a switch rail (12), the switch device having a monobloc design and comprising at least one stock rail (14), a junction rail (18) and a switch rail support (23), and the switch rail (12) and the junction rail (18) being mechanically interconnected. The switch rail (12) and the junction rail (18) merge into each other by means of a joint (20) that is S-shaped in the horizontal section.

A railway switch system includes a base plate that has an exterior surface and a movable elongate rail that has a mounting flange that has an exterior surface that faces the exterior surface of the base plate. The railway switch system includes a lubricious liner disposed between the base plate and the mounting flange and mounted in parallel engagement on top of a substrate that is one of: the exterior surface of the base plate, the exterior surface of the mounting flange, and an exterior surface of an intervening plate disposed between the base plate and the mounting flange. The lubricious liner has an exposed bearing surface, has a second width, extends continuously across the second width, and is substantially planar. The lubricious liner consists of a non-metallic graphite free material consisting of a blend of polymer resin, fibers and a lubricant.
