An update on Knorr-Bremse Rail Systems UK’s £3.67 million project, which will see ScotRail integrate its Wheel Slide Protection (WSP) technology on 52 HSTs.

The contract began in 2024 and is planned to be completed in August 2025.

The work to the 52 High Speed Trains is being carried out at ScotRail’s Haymarket depot where a team has a dedicated facility for the contracted work.

The contract has created 14 new roles within Knorr-Bremse Rail Systems UK due to having set up an office and welfare facilities at the depot.

The Wheel Slide Protection technology will improve the reliability of ScotRail’s Inter7City High Speed Train fleet, creating better journeys for passengers across the region.

Previously, Knorr-Bremse has fitted over 2,000 vehicles with this technology; however, this project is the first time they have managed the design, installation and management of the technology

The work includes removing the axle end covers, installing toothed wheels to the axle ends and equipping them with speed probes and fitting conduits and connection boxes onto the frames.

The system has been proven to improve the running of trains, including those on the Midland Main Lines. ScotRail’s fleet of electric multiple units is already fitted with this technology.

Both Knorr-Bremse and ScotRail have been working closely during the contract and have reaffirmed their commitment to advancing rail transport.

“This project showcases the dedication and skill of our Field Service Delivery team. Their work has been instrumental in integrating our Wheel Slide Protection technology into ScotRail’s fleet.”
