TEG - Track Experts Group
Overview
Background & policy context:
The TEG is working on: The engineering of Asset management for existing track and S&C, Take initiative to develop new and enhanced track solutions and methods, Active influence on European codes and standards, Handle environmental questions, Active work concerning interactions from vehicles , Handle upcoming questions.
The aim of the TEG is comparing existing practice among the participating Infrastructure Managers and identifying the existing correlations between on-site and laboratory results.
Objectives:
The project aims to define harmonised LTR testing methods for both track and laboratory conditions. The assessment and control of lateral track resistance is a safety-related issue that needs to be perfectly understood and mastered.
Methodology:
The project will consist of four parts with the main following objectives:
1) Unloaded Lateral Track Resistance in track
On track measurements will be carried out in several sites of some participants’ networks.
The different methods and their results will be associated with some already existing data provided by the different partners.
Measurement results in various track conditions will be scrutinized and compared together regarding their representativeness, their reproducibility, robustness and efficiency in order to identify and describe a single standardized methodology.
2) Unloaded Lateral Track Resistance in laboratory
Laboratory measurements will be carried out according to three different methodologies which will be compared.
3) Search for correlations
Existing correlations will be searched between laboratory and on-track measurements, to assess the ability of laboratory methods to account for real conditions and to provide the keys to reading the laboratory results in a reliable and representative way.
4) Synthesis and guidelines
In this final phase, a synthesis report will describe the recommended techniques and their interpretation methodologies.
A draft UIC standard will be derived and relevant impacted leaflets will be updated.
