Summary of the contracting process

ScotRail Trains Limited has recently awarded a contract to Siemens Mobility Limited for the design, certification, supply, and installation of a Single Variable Rate Sanding (SVRS) system on ScotRail’s Class 158 Diesel Multiple Units (DMUs). The procurement falls under the industry category of railway and tramway locomotives and rolling stock and associated parts, and is classified as a goods procurement. This particular procurement process has reached the award and contract stage, with the contract signed on 22 April 2025. The SVRS system is critical for improving braking performance under low-adhesion conditions, with manufacturing and installation scheduled to commence in Autumn 2025 at ScotRail engineering depots in Inverness and Haymarket, UK.

This contract presents significant opportunities for businesses specialised in railway safety systems, engineering, and rolling stock components. Suppliers like Siemens Mobility Limited benefit from having proven solutions with required certifications and the ability to meet stringent project timelines, making them well-suited to fulfill the technical and urgency demands of such procurement processes. The project requires suppliers able to navigate strict regulatory environments, ensuring high safety standards and compliance, thus fostering growth for businesses equipped with advanced technical capabilities and certification credentials in the railway sector.

Notice Title

Design, certification, supply and installation of Single Variable Rate Sanding (SVRS) to ScotRail's Class 158 Diesel Multiple Units (DMUs)

Notice 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.

    "description": "Justification: SRT justifies its use for this procurement under two grounds: 1. Reg 48(1)(c):Only One Provider Available Due to Technical Reasons 2. Reg 48(1)(d) and 48(3): Extreme Urgency Reg 48(1)(c) allows procurement from a sole provider if competition is absent for technical reasons or to protect exclusive rights. Justification: - SRT's safety case mandates the procurement of a fully certified SVRS system by August 2025 to ensure fleet safety. - Porterbrook, the train owner, has mandated in the lease that SRT can only procure an SVRS system which has full engineering change approval. - Siemens Mobility is the sole supplier meeting these technical requirements, making competition absent for technical reasons. In conclusion, SRT's procurement under Regulation 48 is justified due to the absence of alternative suppliers capable of meeting the required specifications and timeframe. Reg 48(1)(d) states that extreme urgency, caused by unforeseeable events, must make compliance with standard procurement procedures impossible. Reg 48(3) further clarifies that the urgency must not be attributable to the utility. Justification: The following incidents on the GB rail network has required SRT to install SRVS on its cl.158 fleet: - The Salisbury collision (Oct 21) due to poor adhesion, involving Great Western Railway and South Western Railway trains, led SRT to implement an initial sanding strategy in 22. - The Powys collision (Oct 24) involving Transport for Wales trains, and multiple station overruns in Autumn 24 indicate an ongoing issue with the cl.158 fleet in low adhesion conditions. - Given these incidents, the current sanding equipment cannot be assumed sufficient for Autumn 25 and beyond. - Urgent procurement of new sanding equipment is required to mitigate the risk of further accidents. - The Powys collision and station overruns highlight a systemic issue rather than isolated incidents, making the urgency unforeseeable but critical. - SRT is bound by its safety case to minimise fleet risk and must act swiftly. - The SVRS system must be supplied by August 25, requiring contract award by March 25. Manufacturing takes 7-8 months, making full competitive procedures unfeasible. - Siemens Mobility is the only provider whose SVRS system has been proven on passenger-services, has previous ROSCO approval, and fully certified. - An uncertified alternative would take at least 18 mths to implement, making Siemens Mobility the only viable supplier for the 2025 deadline.
