213 Implementation of condition monitoring for track section Kiruna-Narvik

Published: 26 August 2019

The purpose is to create the conditions for innovation and implementation of innovations in the rail industry through collaboration. In this case, it is intended to demonstrate vehicle-based state monitoring solution of railway infrastructure on the Kiruna-Narvik route.

The sub project "ePilot 213 - Implementation of condition monitoring for the infrastructure for track section Kiruna-Narvik (IMPKiNa)" has aimed to test and evaluate a mobile measuring equipment on the Riksgränsen-Narvik railway line.
In the sub project, measurements of Ofotbanen's superstructure were carried out with the mobile measurement equipment Track-Logger. The Track-Logger has been mounted on a wagon in one of LKAB's iron ore trains that have been traveling on the Kiruna - Narvik route. The measurements were carried out in the period 02.05.2019 - 23.10.2019. There are measurement data from just over 100 individual trips during this period.
Measurement data from 15 single trips between 30.09.2019 - 23.10.2019, for a selected track section between Søsterbekk and Haugfjell, have been analysed in this sub project and have been compared with data from BanNors conventional the measurment vehicle  ROGER 1000.
The sub project has shown that the Track-Logger provides both consistent and repeatable measurements of parameters such aswarping, vertical geometry / cant and corrugated rail heads. It is thus concluded that the system has generated very promising results.
A mobile equipment such as Track-Logger, in the sub project's estimation, has considerable potential and could be a good complement to ordinary measuring vehicle runs. It is also considered that in the long term a Track-Logger mobile measuring equipment can contribute to a more cost-effective maintenance of the railway. However, there are certain challenges with meter reading as well as being able to measure long track errors due to the low speed of train equipment operating on the Ofotbanen.
