Cambridge South sets new benchmark with UK's first net zero carbon railway station

Cambridge's newest railway station has opened to passengers, marking a significant milestone for sustainable transport infrastructure and becoming what Arcadis describes as the UK's first net zero carbon railway station.

Cambridge South Station, which welcomed its first passengers on 28 June, has been designed to support the city's rapidly expanding biomedical and research sector while showcasing the next generation of low-carbon rail infrastructure.

Backed by more than £250 million of Government investment, alongside funding from AstraZeneca, the Cambridgeshire & Peterborough Combined Authority and the Greater Cambridge Partnership, the project delivers a new four-platform station complete with modern passenger facilities, enhanced public spaces and more than 3.5 kilometres of upgraded railway infrastructure.

Sustainability has been embedded throughout the development. The station features a green roof to help manage surface water during extreme weather, over 1,000 cycle parking spaces to encourage active travel, and extensive landscaping incorporating wildflower meadows, native trees and sustainable drainage systems that create new habitats for local wildlife, including protected water voles.

The station is also the first in the country to carry Great British Railways branding and is expected to serve around 1.8 million passengers every year, improving access to the Cambridge Biomedical Campus, which is forecast to support 27,000 jobs by 2031.

Arcadis provided multidisciplinary services throughout the project, including engineering, design, environmental planning, commercial management and heritage consultancy. The consultancy also utilised advanced digital engineering tools, including 3D modelling, drone surveys and a common data environment to coordinate delivery across multiple stakeholders.

Mike Gardner, Arcadis' UK Head of Stations, described Cambridge South as an example of how transport infrastructure can successfully combine sustainability, biodiversity and community integration, creating a station designed not only to improve connectivity but also to support long-term economic growth while setting a new standard for future rail developments.
