This initiative lies within the construction industry, focusing on rail depot infrastructure and walkways, and is planned to be executed in the UKD72 region. Published on 19th June 2026, the active tender process remains open for submissions until 24th July 2026. The procurement method is an open competition under a JCT intermediate Works with Contractor’s design contract, with the tender period ending on the aforementioned date. This procurement represents a significant opportunity for businesses specialising in construction, particularly those experienced in railway and overhead line construction. The contract, valued at approximately £1,231,900 GBP, demands quality, competitive pricing, and the inclusion of social value criteria within submissions. Suitable candidates would be SMEs with expertise in constructing high-level platforms, capable of meeting stringent safety requirements and integrating with existing overhead line equipment. The awarded contract is set to commence on 6th October 2026 and conclude on 6th April 2027, providing a substantial engagement period for the chosen supplier. ## Notice Northern Trains Limited, is a Train Operating Company (TOC) that operates passenger rail services across the North. Northern Trains Limited is publishing this notice to establish a contract with a single supplier for the construction of full-length high-level access platforms based on designs from RCA Construction, enabling safe working at height along the entire length of four-car trains. These platforms will be compatible with existing fleets (Classes 323, 768, and 331) as well as any future fleets operating at Allerton depot. They will be installed on one road to improve operational flow, particularly in the Planned Heavy Clean (PHC) area. The platforms will incorporate essential safety features, including barriers, fall protection systems, and appropriate signage to ensure safe use by staff. A key functional requirement is the inclusion of a safe method for removing roof-mounted components, such as HVAC units, while minimising manual handling risks. In addition, the high-level access platforms must integrate with existing overhead line equipment (OHLE) isolation systems and the depot protection system. This ensures that the platforms cannot be used unless the overhead electrical supply has been fully isolated, thereby maintaining a high level of safety for maintenance activities. The nature of the arrangement is that works will be supplied under a JCT intermediate Works with Contractors design 2024.
