About increase of reliability and durability of rails of the Minsk Metro
The paper considers the issues of increasing the reliability and durability of the rails of the Minsk Metro. It is shown that the initial grinding and milling of new rails before grading, combined with subsequent reprofiling operations, make it possible to obtain a significant effect in ensuring safe and uninterrupted train traffic by improving the reliability of the track operation and continuing the durability of the lifetime of the rails.
