This project falls under the services category related to repair, maintenance, and associated railway services. The procurement, initially in the planning phase, progressed to the award stage with a direct procurement method, finalising a contract with Siemens Mobility Limited. The key dates for this project included a contract period starting on 6th February 2026 and concluding by 28th August 2028. The procurement initiative aims to enhance train safety across multiple UK regions, addressing incidents that highlighted the need for improved braking systems under low-adhesion conditions. This procurement tender signifies substantial growth opportunities for businesses specialising in railway services and equipment modification. Organisations with expertise in advanced railway technology, particularly those capable of delivering certified and innovative solutions for safety-critical systems, could find such tenders aligned with their offerings. The award to Siemens highlights the demand for proven technological solutions that can meet stringent safety and timeline requirements, underscoring opportunities for companies operating at the intersection of transportation safety and innovation to engage with central government authorities such as Northern Trains Limited. ## 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 Justification: 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. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/007330-2026 | | Notice type | UK6 - Contract Award Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Direct | | Procurement method details | Direct award | | Tender suitability | Not specified | | Awardee scale | Large | | All stages | Planning, Tender, Award | ## Dates | Field | Value | | --- | --- | | Publication date | 27 Jan 2026 | | Submission deadline | Not specified | | Future notice date | 23 May 2025 | | Award date | 27 Jan 2026 | | Contract period | 6 Feb 2026 - 28 Aug 2028 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | £1,790,898 | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Complete | | Awards status | Cancelled | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | NORTHERN TRAINS LIMITED | | Additional buyers | Missing | | Locality | YORK | | Post town | York | | Postcode | YO1 6JT | | Country | England | | ITL 1 | TLE Yorkshire and The Humber | | ITL 2 | TLE2 North Yorkshire | | ITL 3 | TLE21 York | | Local authority | York | | Electoral ward | Micklegate | | Westminster constituency | York Central | | Delivery location | TLC North East (England), TLD North West (England), TLE Yorkshire and The Humber | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | SIEMENS MOBILITY | ## CPV Codes ### Divisions - 50 - Repair and maintenance services ### Codes - 50220000 - Repair, maintenance and associated services related to railways and other equipment ## Release History - 27 Jan 2026 at 18:46 - TenderCancellation - UK12 - Procurement Termination Notice - https://www.find-tender.service.gov.uk/Notice/007330-2026 - 27 Jan 2026 at 18:38 - Award - UK6 - Contract Award Notice - https://www.find-tender.service.gov.uk/Notice/007328-2026 - 27 Jan 2026 at 18:24 - Award - UK5 - Transparency Notice - https://www.find-tender.service.gov.uk/Notice/007326-2026 - 21 May 2025 at 12:21 - Planning - UK1 - Pipeline Notice - https://www.find-tender.service.gov.uk/Notice/023862-2025 ## Documents - https://www.find-tender.service.gov.uk/Notice/007330-2026 27th January 2026 - Procurement termination notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/007328-2026 27th January 2026 - Contract award notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/007326-2026 27th January 2026 - Transparency notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/023862-2025 21st May 2025 - Pipeline notice on Find a Tender ## Notice URLs - https://www.legislation.gov.uk/ukpga/2023/54/contents - https://www.mobility.siemens.com/uk/en.html ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
