System for monitoring the state of railroad switches is successfully tested

Vossloh announced that it has successfully completed performance testing of sensors, gateways, cloud applications and algorithms in a new switch condition monitoring system in Sweden. A multi-year contract providing for the implementation of such a system was signed at the end of 2020 between Vossloh and Trafikverket, the Swedish railway infrastructure authority, and covered 1,000 turnouts. It is reported by Railway Supply magazine with reference to zdmira.

The project involves DB Systemtechnik, a subsidiary of the German Railways (DB), the Dutch company Sensorfy, a developer of IoT solutions and sensors for railway infrastructure, and other partners. The goal of the project is to prevent infrastructure failures due to the failure of turnouts and increase the efficiency of their maintenance.

The system will monitor the performance of points, based on the movement of the bearer combined with speed measurement and a train recognition algorithm. Its functionality, reliability and accuracy of measurements have been confirmed in real conditions by the results of 4000 train passes. The rollout of the system on Swedish railways is scheduled to begin in January 2023.
