Technology for Recovery of Defective Rail Bars

Savin, Alexander / Loktev, Alexey / Korolev, Vadim / Shishkina, Irina

The continuous welded rail track is the main design of the track used by the railways and can be operated in accordance with the technical requirements established by the railways on the tracks of all classes. The paper presents the calculation of the possibility of laying a continuous welded rail track. Analysis of works on temporary and final restoration of welded rail strings is carried out. At the final restoring, rail strings can be welded by electric contact or aluminum thermite welding. Depending on the location of cropped rail or the place of temporary restoration relative to the ends of the restored rail string, the final restoration by electric contact welding can be carried out with tightening of the welded rail string or with its preliminary bending. Final restoration of rail strings by aluminum-thermite welding can be carried out immediately after identification of a dangerous defect requiring cutting or after temporary restoration of the string. Laying of continuous welded track with or without replacement of the assembled rails and sleepers should be carried out in accordance with the projects and technologies approved by the railways. When planning work, it is necessary to take into account daily and long-term forecasts of the rail temperature. During the work, continuous monitoring of the rail temperature, carried out with the help of portable rail thermometers, should be organized.
