A burst water main has caused major travel disruption for passengers travelling between central London and Heathrow Airport after flooding submerged the signalling system. The incident, which occurred on May 30, 2026, has left the UK's busiest airport without any rail or Tube service, compounding planned engineering works that have already suspended the Piccadilly line.
Service Suspensions and Delays
There are currently no Elizabeth line or Heathrow Express services running between Paddington and Heathrow terminals. The flooding, which took place between Paddington and Heathrow, blocked all lines and overwhelmed the signalling infrastructure, according to National Rail. Major disruption is expected to last at least until 11am. Meanwhile, the Piccadilly line is suspended between Heathrow and Acton Town due to planned weekend works, leaving buses as the only public transport option.
Passenger Frustration
Passengers have taken to social media to express their frustration. One traveller said: 'Got through Heathrow quickly, great straight onto the Elizabeth line…. Nope, line is flooded. It's two buses and a train instead.' Another added: 'No Piccadilly line to terminal 5. No Elizabeth line to terminal 5 due to flooding??? Waiting for a bus that doesn't seem to arrive. People will miss their flights! Sort this out!'
Heathrow Airport Statement
Heathrow Airport said: 'There are currently no rail services operating to and from Heathrow. The Elizabeth line and Heathrow Express are currently suspended, and the Piccadilly line is closed between Heathrow and Acton Town as part of planned works. If you are travelling to the airport, please allow extra time and consider bus or coach options. We apologise for any inconvenience caused.'
Alternative Travel Options
The main affordable option to reach the airport is buses, while taxis and private hires are available as normal but will cost more. Passengers with Heathrow Express tickets can use them on Great Western Railway (GWR) services on any reasonable route. The nearest railway stations to Heathrow with GWR services are Hayes & Harlington, West Drayton and Southall stations.
Bus Routes to and from Heathrow
From London Paddington to Heathrow, passengers can take the 27 bus to Hammersmith Broadway (stop F), the 702 bus to High Street Langley (from SC), or the 703 bus to Heathrow Terminal 5. From Ealing, the SL8 bus to The Greenway (stop K) and the 724 bus to Heathrow Airport are available. From Hayes & Harlington, the 278 or SL9 bus from station approach (stop E) can be used. Travelling from Heathrow to central London, buses from all terminals include the 285 to Feltham, the 423 on local routes, and the X26 to Croydon via Kingston.
Transport for London's latest Elizabeth line status shows that the route is partially suspended between Heathrow Terminal 5 and Terminal 4 and Hayes & Harlington, with minor delays on the stretch between Hayes & Harlington and Paddington. The incident is described as being outside of the control of Heathrow Express, which is actively working to resolve the issue.
