GWR services to Reading have been cancelled or disrupted, and the Elizabeth line is suspended between Paddington and Heathrow terminals four and five, as well as Paddington to Reading, with TfL noting severe delays on the Piccadilly line after a trespass incident at Hammersmith.

Widespread passenger disruption emerged at Paddington with crowds stranded as the fire near Scrubs Lane in North Kensington unfolded and six engines with about 40 firefighters were deployed to tackle the blaze.

The airport urged passengers to allow extra travel time and acknowledged ongoing delays on the Piccadilly line as a broader travel impact persisted.

The London Fire Brigade has been contacted for comment on the incident.

Weather conditions keep wildfire risk elevated despite cooler temperatures, with the Met Office Fire Severity Index showing high or exceptional risk in parts of London, including near Heathrow and along coastlines in Essex and Suffolk.

Public updates warned that even after containment and safety clearance, residual delays and cancellations would continue as services are restored and crews are repositioned.

Sources cited include London Fire Brigade, National Rail disruption summaries, and Transport for London status updates.

The fire was extinguished by the early hours of Sunday, and rail operators reported normal services resuming by Sunday morning, though some delays and cancellations remained possible due to train displacements.

There is no precise reopening timeline at the time of reporting; officials expect a staged restoration of services and recommend real-time journey planning.

Context: the fire occurred during a busy late-summer travel period, underscoring the sensitivity of the Great Western Main Line and the airport’s vulnerability to rail disruptions.

The incident highlights Heathrow’s exposure to rail disruptions and could renew calls for more resilient airport-to-central-London connections.

Earlier on Saturday, Heathrow’s southern runway was closed due to a grass fire, causing some flights to divert, following a previous grass-fire incident near the runway weeks earlier.
