A switch device including a switch rail (12), the switch device having at least one stock rail (14), a junction rail (32) and a switch rail support (16), and the switch rail and the connecting rail being interconnected by a weld joint (34). The switch rail support (16) includes a through-opening (36) or a recess beneath the weld joint, the width of the through-opening or the recess being wider than the width of the switch rail (12). Furthermore, the length of the through-opening or the recess allows the junction rail (32) to connect to switch rails of the same or different lengths.

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 switch for a track of a maglev train is provided. The switch comprises a front main track beam and a rear switching track beam. The rear switching track beam comprises a central fixed track beam and a middle mobile track beam; the front main track beam can switch between a straight track and a bent track by bending; the central fixed track beam is a fixed track beam; and the middle mobile track beam can move parallelly between the straight track and the bent track. The imposed deformation length and driving weight of the switch is minimised by providing the middle mobile track beam, and the required track switching time is shortened.

A point switch is designed such that the point plates (1, 2) of the point switch which support the track (11, 12) are placed vertically on top of one another and that the position of the points is set by vertically moving the point plates.

By supporting a space generated by a settlement of the track bed gravel or asphalt roadbed underneath a concrete rail tie with cylindrical rods, and installing the present invention, one each separately, on the left and right sides of the concrete rail tie, recovery from settlements is automatic, and the response to differential settlements of the left and right rails of the track due to the train load can be easily facilitated, and by installing pressure reducing valves on the upper part of the concrete rail ties, pressure can be reduced while maintaining the track system as is without having to dismantle the concrete rail ties, and accordingly the usability of the concrete rail ties can be improved.
