“…2), characterized by more than three times increased productivity compared to existing analogues. The operation of the new rail grinding train is based on the technology of high-speed rail grinding, which was developed at SGUPS and has undergone preliminary industrial testing [9]. Two principles were implemented in the high-speed rail grinding technology:…”

“…2) Increasing the rotation speed of the grinding wheel, which allows you to increase the metal removal rate and lead to a proportional decrease in cutting forces, with the same metal removal. It has been previously established that increasing the rotation speed of the grinding wheel to 5000 rpm will increase the operating speed of the rail grinding train to 15 km/h, and to 30 km/h at 7000 rpm without reducing metal removal [9].…”

The article presents design and technical solutions for the new working equipment of the high-performance rail grinding train PXP 2.0 for the implementation of high-speed rail grinding technology in railway conditions. A description of the design of grinding carts is given, including the drive of the grinding wheels and the mechanism for setting the angle of attack of the grinding wheel. In addition, the article discusses the conditions for moving working equipment along a rail track at high speeds. The presented solutions make it possible to carry out rail grinding work at speeds of up to 30 km/h without reducing the amount of metal removal, which ensures an increase in work productivity by more than 3 times compared to existing analogues of rail grinding trains.

One of the modern methods of connecting railway rails when creating a continuous welded track is thermite welding. The gap between the rails, into which the metal is poured, is 25 mm. However, when repairing rails on the way, it may not be enough to eliminate the defective rail section. Therefore, an increase in the welding gap up to 50 mm is considered a promising direction in the development of thermite welding of rails. T his study presents the results of modeling the process of rail welding by the thermite method using the NovaFlow& Solid CV software package. The purpose of the study was to assess the change in the length of the weld zone and heat-affected zone with an increase in the welding gap from 25 to 50 mm. The results of the simulation are thermograms reflecting the distribution of heat from the weld zone into the rails. These thermograms were used to determine the boundaries of the welded seam and the heat-affected zone. It was found that the use of a welding gap of 50 mm, instead of 25 mm, leads to the increase in the length of the welded seam by 1.3—1.6 times.
