Abstract
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.
