摘要： 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.

摘要： 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.

摘要： In a device for fixing stock rails (1) in railway switches, including a base plate (2) for the stock rail (1) and a sliding chair (3) for the switch tongue mounted on the base plate and comprising an elongated spring element (6) for pressing down the rail foot and preferably having the shape of a plate, the spring element (6) can be introduced, preferably without tension, into a tunnel-shaped recess (5) provided in the sliding chair (3) and extending in a direction approximately normal to the stock rail. The upper edge of the tongue-shaped recess (5) within the sliding chair (3) extends, with the formation of a kink (13), in direction towards the rail foot steeper in upward direction that in an area (11) extending more flatly in front of the kink (13). A separate wedge (10) can, for the purpose of guying the spring element (6) against the rail foot, be driven in within the area (11) of flatter extension of the upper edge at a distance from the kink (13) of the upper edge. On account of the wedges presence, a progressive spring characteristic of the spring element (6) can easily be adapted to the requirements.
