Vossloh achieves substantial progress on the trend-setting order for data-based condition monitoring of switches in Sweden. The multi-year order which was awarded by Trafikverket two years ago covers a total of 1,000 switches in the Swedish network. The aim is to avoid unplanned downtime due to switch malfunctions, increase efficiency of maintenance work and thus significantly boost track availability.

The solution basically monitors the displacement of switches via the movement of the bearer combined with speed measurement as well as a train recognition algorithm. Vossloh has now successfully completed validation of the performance of the sensors, gateways, cloud applications and algorithms. The validation was performed using data of over 4000 train passes to test the reliability of the solution and the accuracy of the algorithms under real conditions. This marks an important technological milestone and is a crucial step to enable Trafikverket in permanently monitoring their railway switches and to avoid unanticipated shutdowns.

The development phase of the project was successfully carried out jointly with DB Systemtechnik GmbH, a subsidiary of Deutsche Bahn AG, and a range of partners including Sensorfy. The rollout will start in January 2023.
