Abstract. Modern methods of performing straightening operations on sections of a welded-on track do not take into account possible increases or decreases in the temperature of fastening of rail lashings, which directly affects the formation of potentially hazardous areas that negatively affect the overall safety of operation. The article proves the fact of the change in the temperature of fastening of rail beams of the weldless path and proposes a technique for taking into account the excessive compressive or tensile temperature stresses that arise as a result of the performance of this type of work.

Abstract. In the article it is proposed to switch to R58 rails instead of P65, it is also proposed to facilitate the weight of the reinforced concrete sleepers. All this in order to improve, especially the conditions of stability, but the strength of the elements of the upper structure of the railway track is not impaired.
