Abstract
This project is being conducted by various institutions as governmental and private
companies as Trafikverket and Alstom, but also with public institution as Lule˚a Tekniska Universitet.
Six people are working on this project. Two persons are from Trafikverket in Lule˚a,
Arne Nissen and Per-Olof Larsson-Kr˚aik; two other persons from Alstom in Paris, Pierre
Dersin and Benjamin Bonnet. The coordinator of this project is Behzad Ghodrati from
Lule˚a University of Technology. The last person working on this project is Marine
Parahy, student at the Technical University of Catalonia (ETSEIB: Escola Tecnica Superior
d’Enginyeria Industrial de Barcelona, UPC), as an exchange student in Lule˚a University
of Technology doing her master thesis while working in this project.
The goal of this project is to obtain significant results implementing field data given by Trafikverket in Alstom’s RDAT (reliability data analysis tool) software in order to find which are the costs drivers for switches and crossings. With these results we will be able to increase the availability of the Swedish railway system cost effectively. The results will probably help to improve the maintenance of switches and crossings in Sweden and also improve the software.
The data we have for this project is field data recorded for several years. The period
over which we will focus is the period between January 1st, 2005 and December 31st, 2009.
Sweden is a particular country very extended in length but with traffic concentrated on
certain corridors. Also another difference with other countries in Europe is the difference of temperature and climate that we have between south and north. The idea is really important for the rest of the study to better understanding the failures on the railway system of switches and crossings.
The distribution of tracks in Sweden is shown in Figure 1. We can see that the country is divided into eight regions (Boden, Stockholm, Göteborg, ˚Ange, Gävle, Hallsberg, Malmö and Norrk¨oping).
