Conditional nod to southern rail link to Heathrow ›

Spelthorne Borough Council has agreed to support a new rail link between Staines-upon-Thames and Heathrow Airport, but only on strict environmental and local benefit conditions.

The proposed Heathrow Southern Rail (HSR) scheme would connect Heathrow Terminal 5 directly to the south-west rail network, using existing track between Staines and Windsor before running in a new tunnel under Staines Moor. Supporters say it could slash road congestion, help people reach work at the airport, and give the town’s economy a boost.

Councillors say they welcome the idea in principle but have made clear that their backing comes with safeguards. They want guarantees that trains will actually stop at Staines, that there will be no damage to the sensitive Staines Moor landscape, and that the council will get to sign off on final plans once detailed studies are complete.

Cllr Chris Bateson, who led the council’s review, told the BBC’s Local Democracy Reporting Service: “We’ve looked at both proposals in detail. A direct rail link from Staines to Heathrow could reduce congestion and support our local economy. But we must protect Staines Moor and make sure residents benefit.”

His colleague, Cllr Howard Williams, chair of the Business, Infrastructure and Growth Committee, added: “Our support relies on clear guarantees. The environment can’t pay the price for progress. We will keep working with HSR to make sure residents’ interests come first.”

The link would run mainly in tunnel to limit disruption, emerging to join the existing railway near Staines. The promoter, Heathrow Southern Railway Ltd, says the route could remove millions of car journeys to the airport every year and cut thousands of tonnes of carbon emissions.

If built, the line could open in the second half of this decade, though no firm construction timetable has yet been confirmed. Earlier proposals suggested the service could be running between 2026 and 2028, offering a six-minute journey from Staines to Heathrow Terminal 5.

An alternative “Southern Light Rail” idea — which would have involved a surface-level route — was rejected by councillors as too intrusive, with greater impact on privacy and the landscape.

While the majority of councillors supported the HSR plan with safeguards, some voiced concern that the benefits might not be evenly spread across the borough, particularly in Stanwell, where many residents already work at the airport.

The council says it will continue talks with HSR to ensure local voices are heard before any final decision. For now, the message from Spelthorne is clear: Heathrow’s southern rail link is welcome — but not at the expense of Staines Moor or local control.
