FIELD: construction.
SUBSTANCE: invention relates to construction, in particular to railway transport, and is intended for service life extension of turnout switch due to increased area of contact with rolling stock wheels. Method for recovery of turnout switch consists in head machining of worn-out frame rails of turnout switch and project relative position of rolling surfaces; a side working face of stock rail is subjected to machining, with removing 1.0 mm of metal, while maintaining the inclination angle for covering and pressing the blade. Then, after passage of two trains over this turnout switch it is repeatedly subjected to machining of side working face of stock rail, with removing 1.0 mm of metal. Following that, frame rail aligned to the point of switch points is shifted inwards track and fixed by stops.
EFFECT: as a result, service life of turnout switch is prolonged.
