Modern Condition, Analysis of Work and Prospects of Development of Intermediate Rail Fastenings

Abstract

The object of the study is intermediate rail fastenings used to attach rails to sleepers. The monitoring of technical characteristics and economic indicators of structures of domestic and foreign production with the analysis of their work is given. An integrated approach to the study of rail fastenings as the part of the upper structure of the track is proposed and prospects for the development of fastening units using modern materials in their structures are determined.
