Auto-Reconfiguration Signalling Power Supply Systems - Preliminary Market Engagement
The procurement contact named on the official 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.
