EBER Track Lab reduces track buckling

Purpose and goal

Track buckling is a severe problem during warm days for the railway. Currently there are only disruptive and expensive ways of monitoring this parameter. The project has developed and tested a new sensor configuration that in an innovative way, that later on, make it possible to determine rail stress free temperature and thus reduce the risk of a buckling can occur. The project´s objectives have been met.

Expected results and effects

The sensor configuration with associated electronics and mechanics have been designed and tested. The equipment functioned as planned.

Planned approach and implementation

A subcontractor specialized in this type of measurement has performed work on the prototype. The partnership has worked very well. Infranord have set up their resources to carry out test measurements. The evaluation has been conducted in cooperation.
