Sustainable railway infrastructure

Published: 9 October 2014

Within the EU project Mainline researchers has to developed new methods to extend the life and optimize costs for railway infrastructure. Within the framework of the project researchers in Structural Engineering at Luleå University of Technology have tested the bridge over the River Aby and the mining bridge in Kiruna with extreme pressure.

- Our pressure testing of bridges are quite unique in this project and has gained some attention, says Professor Lennart Elfgren from research Structural Engineering at Luleå University of Technology.

Luleå University of efforts were made in cooperation with the Swedish Transport Administration, LKAB, Hjalmar Lundbohmsskolan Research Centre (HLRC) and the Swedish Construction University also test burdened bridge over the River Aby and Mining bridge in Kiruna. The project was concluded in Paris on 30 September at a seminar with 50 participants. Twenty technical reports have been prepared and are available on the project website:
