Designed to transfer rolling stock from one track to another or to pass in a straight direction. It is used on 1st and 2nd class railway lines with mixed freight and passenger train traffic. The use of the switch is especially beneficial in cramped conditions. It is interchangeable with the turnout switch of Project 1580. The sharp crosspiece is a prefabricated cast core connected to rail guardrails. The blunt cross is solid cast from high-manganese steel. The counter rail is not connected to the track rail. All linings have high flanges. The frame rails and points are hardened at high frequency.
