The innovative solution addresses the wheel and rail adhesion bottleneck enabling transit systems to improve efficiency and increase network capacity.

Wabtec obtained the certification for its adaptive wheel slip protection (WSP) technology after extensive testing in the laboratory and operational environments. The laboratory tests were conducted in the accredited laboratory of Deutsche Bahn Systemtechnik in Minden, Germany. Wabtec also worked with Eurailtest, an accredited laboratory to test the adaptive wheel slide protection technology in the operational environment of the SNCF Regiolis train.

“This certification opens the door to the use of our new generation of high-performance adhesion solutions on new mainline trains, as well as retrofits on existing trains,” said Lilian Leroux, President of Wabtec Transit. “It includes the SNCF Regiolis fleet, where DistanceMaster will start contributing to reducing maintenance costs this autumn as the rainy season begins and the leaves begin to fall.”

Testing has also shown that Wabtec's DistanceMaster Adaptive WSP system shortens stopping distances and prevents wheel damage even in extremely low adhesion conditions. SNCF played a key role in the innovative project and decided to support the certification process, as SNCF Regiolis trains often run in these low-adhesion conditions.

Adaptive WSP technology enhances the capabilities of DistanceMaster. Overall, DistanceMaster improves train safety by reducing the extension of braking distance in degraded conditions by up to 90 percent. The braking distance extension can be further reduced with the Smart Sanding contribution. The shorter guaranteed braking distance also enables operators to reduce train headway. The solution also improves the management of extremely low adhesion, reducing wheel damage, and thereby reducing maintenance costs.
