Designed to transfer rolling stock from one of the parallel tracks to another and is used on the main tracks of class I and II railway lines with mixed freight and passenger train traffic. The switch uses flexible points of a welded structure, which are rigidly fixed in front of the extruded part on two high pads, and the pressed part is on pads with flanges using elastic clamps. The frame rails are attached to the pads with pads (welded to the pads) and pressed flanges using elastic U-shaped rod clamps. The frame rails have anti-theft linings that interact with anti-theft stops mounted on the blades. The crosspiece of the welded structure is welded to the core 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 ramp of a continuous track, in order to compensate for temperature changes in the length of the rail threads, equalization joints must be laid on both sides of the ramp. After laying the ramp, rail joints, except insulating ones, must be welded with aluminothermic way.
