East West Rail faces growing opposition as pressure mounts over Cambridge route

East West Rail (EWR) is facing renewed criticism over its preferred southern route into Cambridge, with objections from the University of Cambridge, local campaign groups and residents adding to calls for greater transparency ahead of the project's next major planning milestone.

The organisation is preparing to submit a Development Consent Order (DCO) application in 2027 for the section between Cambourne and Hauxton Junction, following the conclusion of its fourth public consultation. However, opposition to elements of the proposed alignment continues to intensify.

University raises concerns over world-leading research facilities

Although the University of Cambridge continues to support the principle of the southern approach into the city, it has warned that the current alignment could have significant

consequences for some of its internationally recognised research facilities.

Central to its concerns is the Mullard Radio Astronomy Observatory (MRAO) near Harlton, where the proposed railway would pass within approximately 150 metres of highly sensitive scientific equipment.

In its consultation response, the University argues that vibration and electromagnetic interference generated by passing trains could compromise the observatory's precision instruments, potentially affecting internationally important scientific research.

The institution also expressed disappointment that concerns it first raised during previous consultations had not, in its view, been adequately addressed.

Having previously urged East West Rail to undertake detailed studies into the potential impacts on the observatory, the University now says it remains opposed to the section between Comberton and Cambridge, stating that it has yet to see sufficient evidence that its concerns have been meaningfully considered.

East West Rail pledges continued engagement

East West Rail has rejected suggestions that it has ignored stakeholders, insisting it has maintained a constructive relationship with the University throughout the project's development.

External Affairs Director Natalie Wheble said the organisation was now reviewing all consultation responses received and acknowledged the significance of the issues raised.

She also noted that the University recognised the wider benefits the railway could deliver, including significantly improved connectivity between academic sites and faster journey times that could enhance research collaboration.

Communities question route selection

The University is not alone in challenging aspects of the scheme.

Communities along the proposed alignment continue to argue that the railway's current design will have disproportionate impacts while delivering limited local benefit.

The Harston East West Rail Working Group has criticised the consultation process, claiming residents' concerns have not been properly reflected in successive revisions of the scheme.

The group says the proposed alignment presents risks to road safety, residential amenity, the local primary school and the area's environmentally significant chalk streams.

Campaigners have also continued to advocate for a railway station serving Harston, arguing the community would otherwise experience the disruption associated with the railway without receiving direct transport benefits.

Brian Williamson, representing the Harston campaign group, questioned both the project's route selection and its economic justification, saying local communities had repeatedly sought greater transparency over the business case.

Business case remains unpublished

A recurring criticism from campaigners is the continued absence of the project's Outline Business Case (OBC).

Despite repeated requests from local representatives, East West Rail and the Department for Transport have yet to publish the document, with current indications suggesting it will not become available until 2027, alongside the DCO process.

Opponents argue that the lack of publicly available economic analysis makes it difficult for communities to fully assess whether the chosen route represents the best value for taxpayers.

Comberton residents seek route changes

Further concerns have emerged in Comberton, where residents have launched a petition calling for East West Rail to reconsider the proposed alignment.

The railway would pass close to the village and Comberton Village College, prompting fears over visual intrusion, noise and long-term impacts on local amenity.

Campaigners say design revisions made since earlier consultations have reduced the depth of a planned cutting, potentially increasing the railway's visibility and its effect on nearby homes.

Residents also question why the line passes so close to the village despite there being no proposed station, arguing that communities should see tangible transport benefits if they are expected to accommodate major infrastructure.

East West Rail defends its design

East West Rail says the current alignment reflects a careful balance between engineering constraints, environmental considerations and land impacts.

The organisation says it has sought to maximise the distance between the railway and Comberton wherever possible while avoiding significant effects on neighbouring sites, including Cambridge Meridian Golf Club.

It also maintains that it has engaged extensively with parish councils, residents and campaign groups throughout the consultation process.

Alternative route ruled out

Campaigners recently met Rail Minister Lord Hendy, East West Rail Chief Executive David Hughes, Liberal Democrat MP Pippa Heylings, and representatives from affected parish councils to discuss ongoing concerns.

According to notes from the meeting, the minister indicated that no alternative route is currently under consideration, reinforcing the Government's commitment to progressing the preferred southern alignment.

Critical phase approaches

As East West Rail moves towards its Development Consent Order submission, the project enters one of its most important stages.

While the strategic case for improving east-west connectivity across England remains widely supported, the growing number of objections illustrates the challenge of delivering nationally significant infrastructure while addressing the concerns of affected communities, protecting internationally important research facilities and maintaining public confidence in the planning process.

How East West Rail responds to those concerns over the coming months is likely to play a significant role in determining the level of support—or opposition—the project faces as it enters the formal planning system.
