Vossloh has won an order from Trafikverket for the delivery of data-based condition monitoring systems for 1000 turnouts. According to the German company, these systems will help understand the technical position of turnouts and improve their efficiency in maintenance and provide higher track availability. Trafikverket allocated the order to Vossloh and it will be carried out in a joint agreement with DB Systemtechnik GmbH, a branch of DB.

“The permanent sensor-based monitoring of the rail track forms the basis for condition-based and in perspective predictive maintenance of rail infrastructure,” explains Oliver Schuster, CEO of Vossloh. “The resulting higher availability of tracks is a central requirement for shifting more traffic to the railway in the future.”


The main technological function is the sensors that collect data on selected parameters. The technology continuously records the track and automatically transmits the data information to Vossloh’s cloud-based platform. The platform processes the data and converts it into actionable corresponding recommendations for the customer. These processes are done using algorithms based on artificial intelligence.

Turnouts are considered to be one of the most technically complex in the entire rail track. Furthermore, maintenance generates great costs. The costs are due to turnouts interfacing with control systems, signalling systems, grinding procedures, welding processes electrical engineer track construction and switching technology. Vossloh CEO believes that achieving climate targets will require passengers to shift to rail transport. Broadening the understanding of rail track physics especially turnouts plays an important role in rail infrastructure and safety for passengers.
