This procurement, currently in the planning stage, is strategically important for understanding market capabilities and informing future tender strategies. The focus is on signalling equipment within the utilities sector, addressing challenges like component obsolescence and sustainability pressures. Interested parties are invited to participate in a Soft Market Testing questionnaire available on the BravoNR platform, with submissions due by 20th April 2026. This engagement seeks insight into supplier capabilities and innovative solutions to support Network Rail's asset strategy, with the project timeline envisaged to span from January 2028 to December 2031. This tender presents substantial opportunities for businesses specialising in signalling equipment and related technologies, with an emphasis on developing cyber-secure, modular, and maintainable platforms. It is particularly conducive for SMEs and voluntary, community and social enterprises (VCSEs) due to the engagement focus on sustainability and technological innovation. Companies capable of offering solutions that enhance maintainability, improve passenger and freight safety, and support digital railway capabilities are well-positioned to benefit from this procurement opportunity. Collaborating with a major public undertaking like Network Rail could pave the way for growth in infrastructure and engineering sectors. ## Notice Network Rail operates a large portfolio of Auto Reconfiguration systems used to support the resilience of 400V TN S and 650V IT signalling power supplies. Many of these systems have been operational for more than two decades and face several challenges: * Obsolescence of essential components affecting maintainability and availability * Reliance on legacy telecoms (such as 3G) due to national network withdrawals * Rising failure risk due to ageing cables, switchgear and protection components * Limited diagnostic capability in existing systems * Inconsistent compatibility with modern power protection and monitoring solutions * Increasing sustainability pressures, including carbon reduction and waste minimisation To support Network Rail's long-term asset strategy and maintain operational performance, we are exploring a future programme to introduce a modern, cyber secure, modular, maintainable Auto Reconfiguration SPS platform. This aligns to wider organisational objectives including: * Improving safety and reliability for passengers and freight * Supporting digital railway capabilities * Reducing operational carbon * Enhancing maintainability * Delivering sustainable whole life value This preliminary market engagement will help confirm commercial viability, test supplier capability, and identify innovative approaches to support a future-proofed solution. It also seeks to understand the level of interest from the supply chain for any future tendering activity. ### Planning Information This PIN seeks to explore via a Soft Market Testing questionnaire some key information regarding the supply of auto-reconfiguration signalling power supply systems. This will help inform Network Rail generally about the supply market and also help inform any strategies should a procurement event take place. All instructions relating to submission can be found within the PIN document which is accessed via BravoNR. Questionnaire submissions, should your organisation wish to take part, are to be submitted by 12:00 20/04/2026 via BravoNR unless this deadline is extended. In the event of queries, please only raise these directly with Network Rail via the BravoNR messaging function.
