INTELLISWITCH: Intelligent Quality Assessment of Railway Switches and Crossings

In a railway network of any size switches and crossings (S&Cs) are both a very necessary object as well as a major cost driver for maintenance and renewal. This project aims at significantly improving the safety, reliability and operational lifetime of the 3500 switches and crossings (S&Cs) in the Danish railway network.

 

Objective of the project

 
In a railway network of any size switches and crossings (S&Cs) are both a very necessary
object as well as a major cost driver for maintenance and renewal. The overall objective of this
project is to provide tools for reliable condition assessment of both visible and hidden parts of
S&Cs. The specific objectives, within the duration of the project, are:

  • To develop a holistic model capable of assessing the condition of individual S&C by
    combining fault diagnostics input from conventional measurement vehicles and new
    strategically placed sensors with metallurgical characterisation of key components and
    dynamic modelling of wheel-rail interaction.
  • To use this model to produce one or more maintenance performance indicators (MPIs)
    for the condition of S&Cs using existing data – such as measuring vehicle data – as
    inputs, thereby making it possible to replace corrective maintenance with condition
    based maintenance and renewal.

A successful outcome of the project will have a significant positive influence on maintenance procedures and renewal of railway infrastructure, and the scientific results will be of broad interest in the railway research community and beyond.
