Project Profile: Cambridge South Station

The Cambridge South Station is a major UK infrastructure project enhancing regional connectivity for the Cambridge Biomedical Campus, a key economic and research hub. This profile details the technical specifications, strategic objectives, and key stakeholders involved in delivering this sustainable transport hub, which became operational in 2025.

Technical Specifications

The station’s core infrastructure consists of a two-storey, twin-building design accommodating four platforms, including a central island platform configuration to manage high passenger volumes. Full step-free accessibility is engineered through two main entrances with lift access and a secondary footbridge. The superstructure is notable for its curved, ergonomic roof constructed from laminated wooden beams, which integrates a significant array of solar panels and a green roof system designed for rainwater harvesting and biodiversity gain. This reflects the project’s adherence to stringent environmental standards required for its location within the Green Belt.

Track and systems integration was a critical engineering challenge. The project involved a major refurbishment of the existing track layout, the installation of two new track loops to increase capacity and operational flexibility, and significant upgrades to the nearby Shepreth branch junction. New overhead line electrical (OLE) infrastructure was installed to support electric rolling stock. To facilitate these upgrades, two private level crossings were permanently closed and replaced with safer, alternative access routes, enhancing the safety and efficiency of the rail corridor.

Key Takeaways

• Economic Catalyst for Life Sciences: The station is a strategic enabler for the Cambridge Biomedical Campus, providing direct, sustainable transport for a workforce projected to support 27,000 new jobs and stimulate associated housing development.
• Enhanced Regional and National Connectivity: By offering direct services to London King’s Cross, London Stansted Airport, Ely, and Birmingham, the station significantly reduces reliance on road transport, alleviates regional traffic congestion, and integrates Cambridge more effectively into the national rail network.
• Benchmark for Sustainable Infrastructure: The project sets a precedent for environmentally responsible development in sensitive locations. The integration of solar panels, a green roof, rainwater harvesting, and extensive cycle parking (1,000 spaces) demonstrates a holistic approach to minimizing carbon footprint and promoting sustainable travel.
