Suspected gas leak evacuates Farringdon station, disrupting London rail services

A suspected gas leak forced Farringdon station to evacuate at the height of the morning rush, shutting a Zone 1 interchange that links the Circle, Hammersmith & City and Metropolitan lines with the Elizabeth line and Thameslink.

British Transport Police said officers were called to the station at 09:42 BST on Thursday, 30 April 2026, after reports of a suspected gas leak. A small number of passengers said they had felt unwell, and the station was cleared while officers carried out enquiries. London Ambulance Service and London Fire Brigade were attending as authorities moved quickly to assess the risk and protect passengers before service was restored.

“Officers are in attendance, alongside Ldn_Ambulance and LondonFire, and the station has been evacuated while enquiries are conducted.”

The shutdown rippled through a network that depends heavily on Farringdon as a central connector. National Rail said there would be no services at the station until 13:00, leaving morning travellers to reroute across London. Thameslink advised passengers to use alternative stations including City Thameslink, via the Holborn exit, or London St Pancras International, underscoring how much pressure a single incident can put on nearby terminals.

The Elizabeth line was also hit, with Transport for London saying the line was part-suspended between Paddington and Abbey Wood. Passengers were advised to use London buses to or from Farringdon at no extra cost, a temporary measure meant to keep people moving while rail services were suspended.

Farringdon’s role in the capital’s transport system helps explain the scale of the disruption. The station is a key interchange in central London, serving both conventional Underground routes and the Elizabeth line, which opened in May 2022 and quickly became one of the city’s most important cross-London corridors. That combination of rail, Underground and cross-city services means even a short closure can cascade across commuter journeys, especially during peak hours when passengers have fewer easy alternatives.

The response showed the trade-off at the heart of emergency operations in a major capital transit hub: speed matters, but so does caution. By evacuating the station and bringing in police, ambulance crews and firefighters, authorities prioritised public safety first, even as the disruption spread across one of London’s most heavily used interchange points.
