Overview

DB ESG's wheel slide protection evaluation rig (WSPER) is a real time ‘hardware in the loop’ simulation facility, which improves operational safety and vehicle availability, reduces whole life maintenance costs of wheelsets and consistently maximises braking performance in all adhesion conditions.

WSPER is used by railway organisations to evaulation the low adhesion performance of full train braking systems.


WSPER - New brake system technology laboratory

WSPER makes the equipment believe that it is fitted to the train recreating realsitic operational conditions. The rig can also measure the effectiveness of adhesion equipment, such as sanders.

Validation, Accreditation and Standards

Combined with the real track based adhesion profiles, the WSPER facility has gained recognition in the UK and overseas for its ability to accurately represent the low adhesion behaviours observed in service.

Our WSPER Testing Laboratory is accredited and regulated by the United Kingdom Accreditation Service (UKAS), in accordance with International Standard ISO/IEC 17025:2017. This provides us with a recognised industry mark of quality and demonstrates our technical competency for the defined scope specified in our schedule of accreditation.
