In a switch including a main track and a branch track, wherein one rail of each track is each configured as a tongue rail and movable into abutment on the respective stock rail, at least one stock rail (), in its region of abutment on the tongue rail (), is designed to have a reduced rail head width as compared to the region located outside said region of abutment, wherein the rail head width, starting from the tip () of the tongue, decreases as far as to a point () at which the carrying wheel comes into lateral contact with the tongue rail () and increases in the region following thereupon, and that the tongue rail () is designed to be reinforced in cross section towards the stock rail () according to the reduction in the width of the stock rail head.

Points comprising a reinforced switch tongue blade

A railway structure for a sliding chair (2), a sliding plate and a ribbed plate (1), respectively, for railway switches or railway crossings. The structure includes friction-reducing sliding members (4, 5) of synthetic plastic material being releasably mounted within recesses (3) in the sliding chair (2) and the plates, respectively. There are accommodated within each recess (3) at least two sliding members (4, 5) having their side surfaces engaged over the major part of the periphery by inwardly protruding walls or profiles of the edge of the recess, so that there results a safe mounting in position of the sliding members (4, 5). The structure makes the interchange of the sliding members a simple procedure.

Sliding chair, sliding plate and ribbed plate, respectively, for railway

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.

Device for fixing stock rails in railway switches as well as process for

In an arrangement for fastening stock rails, wing rails or track rails (1) at the side being averted from the running edge, in which arrangement a strap (5) is pressed against the web of the rail with interposition of a leaf spring (9) or, respectively, of a spring pile, the strap (5) is given a convex shape at its outer side facing the leaf spring (9), whereby a defined pressure point (D) is provided for the attack of the leaf spring (9).
