Major Grass Fires Disrupt Heathrow Rail Links and Airport Runway
9/6/2026, 9:23:08 PM
Rail Disruption Caused by Trackside Grass Fire
On Saturday afternoon a grass fire ignited beside a railway line near Scrubs Lane in North Kensington, close to London Padding0n. The blaze caused an electricity failure, prompting National Rail to block all lines between Paddington, Heathrow’s terminals and Reading. Heathrow Express services were halted, the Elizabeth line was suspended between Paddington and Heathrow Terminals 4-5 and between Paddington and Reading, and Great Western Railway cancelled its services to Reading. About 380 passengers stranded on an Elizabeth line train were evacuated by the fire service and TfL. The London Fire Brigade deployed six fire engines and around 40 crew members. Heathrow Airport advised travellers to allow extra time and suggested using the Piccadilly line, which also experienced delays.
Airport Runway Closure Due to Adjacent Grass Fire
On September 6, 2026 a grass fire broke out adjacent to runway 27L at Heathrow. Emergency crews were dispatched and the runway was temporarily closed, shifting the airport to single-runway (27R) operations. By midday arrivals and departures were redirected to runway 27R and the fire was extinguished within an hour, allowing dual-runway operations to resume. Heathrow’s spokesperson said both runways were fully operational shortly after the incident.
Background & Context
The two incidents followed a previous grass fire near Heathrow’s southern runway that forced 18 flights to divert and damaged a large area of grassland. Although temperatures have cooled since a record-breaking summer, the UK Met Office’s Fire Severity Index still rates fire risk as “high” across southeast England and “exceptional” in parts of London, including the Heathrow area. Authorities have warned of elevated wildfire risks despite the cooler weather.
Data & Statistics
- Fire-fighting resources: six fire engines and roughly 40 firefighters for each incident.
- Passengers evacuated: about 380 from an Elizabeth line train.
- Rail services cancelled or suspended: Heathrow Express, Elizabeth line (Paddington-Heathrow and Paddington-Reading), Great Western Railway to Reading.
- Airport impact: at least two flights diverted during the runway fire; no total delay figure released.
- Ticket policy: passengers with tickets for the disrupted Saturday were allowed to travel on Sunday at no extra cost.
Official Statements & Responses
National Rail called the situation a “major disruption” and confirmed the line block after the electricity failure. The London Fire Brigade reported the same resources were sent to both sites. Heathrow’s spokesperson emphasized the swift response and that both runways were back in service. Great Western Railway warned of service cancellations to Reading and noted an amended timetable for early services. TfL advised passengers to use alternative routes, including the Piccadilly line, which also suffered delays due to a separate trespasser incident.
Impact on Travelers
The rail disruption forced passengers onto the Piccadilly underground line or local buses. Heathrow’s advice to allow additional travel time reflected the combined effect of rail cancellations and the brief runway shutdown. The temporary single-runway operation created a bottleneck that led to minor knock-on delays for flights that day.
Outlook
The Met Office continues to flag high wildfire risk for the region, suggesting that similar incidents could recur if vegetation near transport infrastructure ignites. Ongoing monitoring and rapid emergency response remain critical to minimizing disruption to both rail and air travel at one of the world’s busiest transport hubs.
