A fire near a train track in the London Paddington area has caused major disruption, with all rail services to Heathrow Airport blocked. The fire triggered an electricity supply failure, leaving all lines between Paddington and the airport unusable, according to National Rail.
National Rail said cancellations and delays to services are expected until 7.15pm. Photos shared on social media show large plumes of smoke rising from the Paddington area, visible for miles.
Heathrow Express and Elizabeth line suspended
The Heathrow Express confirmed that no trains are running in either direction between Paddington and Heathrow. Great Western Railway (GWR) services to Reading have been cancelled, while the Elizabeth line is part-suspended.
Transport for London (TfL) said the Elizabeth line is suspended between Paddington and Heathrow terminals four and five, and between Paddington and Reading. The line to Abbey Wood is experiencing severe delays.
Airport and TfL advise extra travel time
Heathrow Airport advised passengers to allow extra time for their journeys, noting that the Piccadilly line, which also serves the airport, is experiencing delays. TfL reported severe delays across the entire Piccadilly line due to an earlier trespasser at Hammersmith.
GWR said trains may be cancelled, delayed, or terminated at and started back from Reading, with disruption expected until 7pm.
Ongoing response and updates
London Fire Brigade has been contacted for comment. The situation remains live, with updates being provided as they emerge.
