The aim of this project was to reduce the risk of wheel damage on the Class 15X diesel multiple units due to leaf fall in autumn, by fitting a new Wheel Slide Protection System (WSP).
How does it work?
WSP is a system fitted to most passenger trains to prevent the wheels from locking up due to low adhesion between wheel and rail.
In autumn 2016, one Class 156 unit fitted with our new WSP was operated in service at Greater Anglia . The results were remarkable with no wheel damage from flat spots seen and the unit remained in service for almost a year without requiring wheel reprofiling.
Porterbrook Leasing, SNC-Lavalin, Loram UK, Knorr Bremse Rail Services and Greater Anglia received the “Engineering and Safety Award” at the Rail Industry Innovation Awards. The new Wheel Slide Protection (WSP) system has been successfully demonstrated in Greater Anglia’s Class 156 diesel multiple units.
