Switch switch on reinforced concrete beams type P65, grade 1/11, project PTKB TsP 2750.00.000

Designed to transfer rolling stock from one track to another. It is used on the main tracks of class I and II railway lines with mixed freight and passenger train traffic. The arrow uses flexible points of a welded structure, which are rigidly fixed in front of the pressed part on two high pads, and the pressed part is on pads with flanges using elastic clamps. The frame rails are attached to pads with pads (welded to the pads) and pressed flanges. There are anti-theft linings on the frame rails that interact with anti-theft stops mounted on the blades.

The crosspiece is a welded structure - the rail end is welded to a core made of high-manganese steel. The counter rail is made from an angle, is not connected to the track rail, and is mounted on stops welded to the pads. The rail is fastened using elastic U-shaped rod terminals. When adjacent to a turnout on a continuous track, to compensate for temperature changes in the length of the rail threads, equalization joints must be laid on both sides of the turnout. After laying the turnout, rail joints, except insulating ones, must be welded using the aluminothermic method.
