Abstract

This contribution focuses on issue of the autonomous monitoring of selected dynamic parameters of the railway lines test sections under conditions in the Czech Republic. Description of the possibilities of such data collection, including the designed hardware and software, is a part of this contribution. At the same time, the contribution describes application of such a measuring system, comparing the selected dynamic parameters of the two types of switches, the first one was a switch with a standard fastening node, the other one with an elasticized fastening node. Recommendations and conclusions of railway infrastructure manufacturers and railway line managers are parts of this contribution, as well.

Highlights

  • The railway line represents a multilayer system determined for the motion of railway vehicles including the equipment necessary for ensuring the safety and smoothness of the railway traffic

  • Measurements performed on real railway structures are very important

  • At the beginning of the Fourth Industrial Revolution, it is certainly worth considering thinking about the implementation of the smart railway structures, which would automatically inform a main system of their status and/or any changes in their status

Summary

Introduction

The railway line (or the tram line) represents a multilayer system determined for the motion of railway vehicles including the equipment necessary for ensuring the safety and smoothness of the railway traffic. The main function of the gravel ballast is to resist the vertical, cross and longitudinal forces and at the same time to hold the track length in a precise geometrical position. Related to the rising speed on the railway tracks, the dynamic effects acting on the rail structure increase, as well. These effects negatively influence the rails and lead to the development of failures and defects. The superstructure has been practically developed to its perfection during more than 150-year railways, new technical solutions can still be found This holds good especially for different types of turnout structures, various rail fastenings, various types of rail pads, sleepers, anti-vibration measures etc. Development and application of new experimental procedures for evaluation of the quality and usefulness of particular structural solutions must be in accordance with this trend
