## Summary

Northern Trains Limited, a central government public authority, has completed a procurement process for the modification of its Class 158 fleet with a Single Variable Rate Sanding (SVRS) system, awarding the contract directly to Siemens Mobility Limited. This procurement, categorised under utilities services, addresses the railway industry, specifically focusing on repair, maintenance, and safety enhancements. Fitting of the SVRS system, aimed at improving the safety of Class 158 trains in low-adhesion conditions, is set to commence in August 2026. Siemens Mobility Limited, the sole viable provider of this solution within the required timeframe, is tasked with both supply and certification, addressing recent safety incidents on the GB rail network. The contract period extends from 6th February 2026 to 28th August 2028, highlighting key procurement stages such as the award and signing in early February 2026.

This contract presents substantial growth opportunities for related businesses, particularly those in railway maintenance and safety equipment sectors. By being involved with a large-scale provider like Siemens, SMEs could potentially collaborate on ancillary services or components related to the procurement. Although the contract specifies a direct award due to technical requirements, businesses specialising in railway safety enhancements could gain insights and develop compatible solutions for future tenders involving similar safety systems. Companies within the repair and maintenance industry, possessing expertise in railway equipment, may position themselves as key suppliers or subcontractors in subsequent related procurements or technological advancements.

## Notice

The design, supply and certification of a proven Single Variable Rate Sanding (SVRS) for Northern's Class 158 fleet, consisting of eight three car and forty five two car units, with fitment commencing August 2026.

### Procurement Information

Northern Trains Limited (NTL) is required to procure and install a fully certified and previously proven SVRS system by leaf fall 2026, ensuring fleet safety of NTL's Class 158 rolling stock. The following incidents on the GB rail network has required NTL 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, the Powys collision (Oct 24) involving Transport for Wales trains and multiple station overruns in 2024 and 2025. Given these incidents, there is a need to enhance the stopping capability of the Class 158 as a safety imperative. Siemens is the only provider whose SVRS solution has proven to positively impact breaking in low-adhesion conditions on Class 158s while in passenger service and is permitted for use by the asset-owner. This has been demonstrated at ScotRail. Any alternative would not meet the timelines required by the Office of Rail and Road (ORR) and Department for Transport Operator (DFTO), making Siemens the only viable supplier for the Autumn 2026 deadline. In conclusion, NTL's procurement under Schedule 5 paragraph 6 is justified due to the following reasons: a. There are no alternative suppliers with a tested solution meeting the technical requirements for Class 158s in the timeframe required by the ORR to address a safety critical matter. b. There are no reasonable alternative goods meeting the technical requirements for Class 158s in the timeframe required by the ORR to address a safety critical matter.
