Abstract

Theoretical and practical research of conditions of interactions of work surfaces of open-quarry locomotives with rails were conducted, rational roughness values for rail profiling were defined to reduce the run-in period for wheel-rail pair to improve the period of the efficient operation of open-pit railway transport.

Keywords
