Description

Turnkey solution for the design, certification, supply, and installation of Single Variable Rate Sanding (SVRS) for ScotRail’s Class 158 Diesel Multiple Units (DMUs). ScotRail requires an SVRS system that has previously received technical approval (i.e., ROSCO approval and full certification through the engineering change process). The SVRS systems must be capable of providing proven improvements in braking performance under low-adhesion conditions for the Class 158 DMU fleet. This must be evidenced by industry performance data demonstrating these improvements specifically for the Class 158 DMUs. ScotRail aims to commence fitment in Autumn 2025 to benefit from the system’s benefits as soon as possible. ScotRail intends to use the negotiated procedure without prior call for competition to contract with Siemens Mobility Limited. This approach is considered the only viable option, as Siemens Mobility is the only supplier who can provide a technically proven solution with demonstrated performance benefits on an in-service fleet and the capability to meet the challenging project timeline.
