Full Description
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.
