London (Britain Today News) September 05, 2026 – A fire near a train track in the London Paddington area has caused major disruption across the capital’s rail network on Sunday, with all services to Heathrow Airport cancelled. The blaze triggered an electricity supply failure that has left every line between Paddington and the airport blocked, National Rail confirmed. Cancellations and delays are expected to continue until 7.15 pm, with knock-on effects reported across the Elizabeth line, Great Western Railway (GWR) services and the Piccadilly line.

What Caused the Disruption at London Paddington?

According to National Rail, the disruption stems directly from a fire that broke out near a train track in the vicinity of Paddington station. National Rail stated that the blaze caused an electricity supply failure, which has left all lines between Paddington and Heathrow Airport blocked. The rail body added that cancellations and delays to services are expected until 7.15 pm.

Photographs circulating on social media show large plumes of smoke rising above the Paddington area, giving passengers and residents an early indication of the scale of the incident before official confirmation of the disruption emerged.

Have All Heathrow Train Services Been Cancelled?

Yes. Heathrow Express confirmed that no trains are running in either direction between Paddington and Heathrow Airport. This means passengers travelling to or from one of the world’s busiest airports have been left without their usual direct rail link, forcing many to seek alternative routes into central London or out to the airport.

The scale of the cancellation is significant given the volume of passengers who rely on the Heathrow Express and connecting services for reliable, time-sensitive airport transfers, particularly on a Sunday when many travellers are heading to or from flights.

What Has Heathrow Airport Told Passengers to Do?

Heathrow Airport has advised passengers to leave extra time for their journeys. The airport further noted that the Piccadilly line, which also runs services to the airport, is experiencing delays, meaning that even the alternative Underground route has not been immune to disruption on the day.

This dual disruption — affecting both the mainline rail options and the Piccadilly line — has left travellers with limited straightforward ways of reaching or leaving Heathrow, increasing the risk of missed flights and lengthy queues at alternative transport hubs.

Which Great Western Railway Services Have Been Cancelled?

Great Western Railway (GWR) has cancelled its services to Reading as a direct consequence of the fire and subsequent power failure. GWR said that trains may be cancelled, delayed or terminated at and started back from Reading, with disruption expected to continue until 7 pm.

This cancellation affects one of the busiest commuter and long-distance corridors out of London, with Reading serving as a key interchange point for passengers travelling further west towards Bristol, Wales and the South West of England.

Is the Elizabeth Line Affected by the Paddington Fire?

The Elizabeth line has been part-suspended as a result of the incident. Transport for London (TfL) said the line is suspended between Paddington and Heathrow Terminals 4 and 5, and also between Paddington and Reading. This effectively cuts off two of the Elizabeth line’s key western branches from the rest of the network at Paddington.

In addition, TfL confirmed that the Elizabeth line service towards Abbey Wood, on the eastern side of the route, is experiencing severe delays, meaning the disruption has been felt well beyond the immediate vicinity of the fire itself.

Why Is the Piccadilly Line Also Experiencing Delays?

Separately from the fire-related disruption, TfL reported severe delays across the entire Piccadilly line. According to the TfL website, this was caused by an earlier trespasser incident at Hammersmith. While unconnected to the Paddington fire, this second incident has compounded the difficulties facing passengers attempting to reach Heathrow, given that the Piccadilly line is one of the principal Underground routes to the airport.

The combination of two separate disruptions on the same day has left passengers with very few reliable options for reaching Heathrow from central London.

When Is Normal Service Expected to Resume?

National Rail has indicated that cancellations and delays are expected to last until 7.15 pm, while GWR has stated that disruption to its services is expected until 7 pm. These timeframes suggest that the disruption, while severe, is anticipated to ease into the evening, though passengers have been urged to check live travel updates before setting out.

Given that rail disruption of this nature can sometimes extend beyond initial estimates, particularly where infrastructure such as power supply has been affected, passengers travelling later in the evening have also been advised to remain cautious and monitor official updates from National Rail, GWR, TfL and Heathrow Express.

What Should Passengers Travelling to Heathrow Do Right Now?

Passengers with flights to catch have been urged to leave considerably more time than usual for their journeys. With Heathrow Express services suspended entirely, the Elizabeth line part-suspended on the relevant branches, and the Piccadilly line facing severe delays of its own, alternative options such as road transport, coach services or rescheduled journeys may need to be considered by those with time-critical travel plans.

Heathrow Airport’s advice to allow extra time reflects the reality that, with three separate rail and Underground routes all affected simultaneously, congestion on remaining services and roads into the airport is likely to increase throughout the affected period.

What Has Been the Reaction on Social Media?

Images shared on social media platforms showing large plumes of smoke rising from the Paddington area have drawn considerable attention, with the visual scale of the fire underlining the seriousness of the incident to those not directly affected by the resulting travel disruption. These images offered an early visual signal of the unfolding situation as official statements from National Rail, GWR, TfL and Heathrow Express followed.

To summarise the position as it stands, National Rail said:

“All lines between Paddington and the airport [are] blocked”

and confirmed that

“cancellations and delays to services are expected until 7.15 pm.”

Heathrow Express stated that

“no trains are running in either direction between Paddington and Heathrow.”

GWR confirmed its services “to Reading have been cancelled,” while noting that

“trains may be cancelled, delayed or terminated at and started back from Reading,”

disruption is “expected until 7 pm.” TfL confirmed the Elizabeth line

“is suspended between Paddington and Heathrow terminals four and five, and between Paddington and Reading,”

while the line “to Abbey Wood is experiencing severe delays.” TfL also confirmed

“severe delays across the entire Piccadilly line due to an earlier trespasser at Hammersmith.”

Passengers are advised to check with National Rail, GWR, TfL and Heathrow Express directly for the latest live updates before travelling, given the fluid nature of the situation and the possibility that timelines for resumption of normal service may change as the evening progresses.
