Designed for transferring rolling stock from one track to another at metallurgical enterprises. The translation is made on the basis of the LPTP.665121.101M project, but is intended for welding into a continuous welding path using an electric contact welding machine. A counter-rail protector made of rolled rails is installed in the front extension of the switch. Three connected stripes are installed on the arrow. The crosspiece is made as a monoblock, rail ends in the front and rear overhangs are welded to a cast core made of high-manganese steel, and rail guards made of rolled rails are attached with horizontal bolts. The counter-rail of the crosspiece is made of rolled rails. All linings have high flanges. The blades and frame rails are HDTV hardened.
