The London Fire Brigade mounted a major response after a large fire erupted alongside a London Overground railway line in Walthamstow, forcing evacuations, disrupting train services, and damaging dozens of properties as Britain faces heightened wildfire risks during an ongoing heatwave.
More than 120 emergency calls were received after the blaze broke out around 6:30 p.m. on a railway embankment near Vallentin Road and Shernhall Street in northeast London.
Flames quickly spread through gardens and outbuildings, affecting around 30 properties and threatening nearby homes.
The incident came as fire services across the UK deal with a surge in wildfires linked to exceptionally hot, dry weather, with officials warning that conditions remain dangerous in many parts of the country.
Large Fire Spreads Through Walthamstow
Around 125 firefighters and 20 fire engines were deployed to tackle the Walthamstow blaze, which spread from the railway embankment into residential areas.
One house was fully alight, while a neighboring property suffered damage to its rear extension.
Firefighters also discovered ten gas cylinders on affected properties and worked to cool them to prevent potential explosions.
The blaze was brought under control at approximately 10:30 p.m., though investigations into its cause are continuing.
Residents in the surrounding area were advised to keep windows and doors closed because of the heavy smoke, while two temporary rest centers were established for people evacuated from nearby homes. No injuries were reported.
Rail Services Suspended After Track Damage
The fire caused significant disruption to the London Overground’s Weaver line.
Services between Hackney Downs and Chingford were suspended while emergency crews worked at the scene, and Transport for London later confirmed that no trains would operate on the route for the following day as engineers carried out urgent repairs.
Fire crews from Tottenham, Bethnal Green, Walthamstow, Chingford, and other nearby stations were involved in the response.
A 100-foot turntable ladder was used as an elevated water tower to help extinguish the flames from above.
Assistant Commissioner Tom Goodall of the London Fire Brigade said crews worked in extremely hot and demanding conditions to stop the fire spreading to additional homes and to support passengers affected by the rail disruption in coordination with Transport for London and British Transport Police.
Emergency Call Diversion Scheme Activated
The scale of the incident led the London Fire Brigade to activate “Operation Willow Beck,” a system introduced in 2022 that allows surplus 999 calls to be diverted to unaffected fire and rescue control rooms during major emergencies.
Officials said the measure helps maintain emergency response capacity when large incidents generate exceptionally high call volumes.
Heatwave Fuels Wildfire Concerns Across Britain
The Walthamstow fire is one of several major blazes reported across the UK as the country endures its third heatwave of the year.
Natural England’s Fire Severity Index has placed much of England at a “very high” risk of wildfire, with some areas of southern England and the Midlands assessed at an “exceptional” level.
Derbyshire Fire and Rescue Service has responded to multiple moorland fires in recent days and declared a major incident because of the impact of a wildfire on Tintwistle Moor.
In London, firefighters also tackled a significant shrub fire near Stratford station on Friday, which caused further rail closures.
Additional crews were sent to a field fire near Sevenoaks Road in Orpington, highlighting the growing pressure on fire services as vegetation becomes increasingly dry and combustible.
Wales and South Downs Also Affected
North Wales Fire and Rescue Service declared a major incident after a wildfire spread near Sychnant Pass on Conwy Mountain.
Residents in parts of the village of Capelulo were advised to evacuate because of smoke drifting into the community.
In southern England, East Sussex Fire and Rescue Service responded to a large open-land fire on the South Downs near Eastbourne, while crews in West Sussex battled a blaze at Devil’s Dyke in the South Downs National Park.
Fire Chiefs Warn of ‘Extreme’ Conditions
Dave Swallow, the National Fire Chiefs Council’s wildfire deputy lead and lead tactical adviser, warned that the combination of dry ground, sunshine, and high temperatures has significantly increased the likelihood of wildfires.
He urged the public to take extra care in the countryside and to avoid activities that could accidentally start fires during the current spell of hot weather.
Record-Breaking Summer Temperatures
The Met Office said 2026 has already become the first year on record to experience temperatures of 35°C or higher on six separate days, surpassing the previous record of five such days set in 1976 and 2020.
The year has also become the first in which temperatures of at least 35°C have been recorded in three different calendar months.
Meteorologists say the UK has already experienced nine days with temperatures reaching 34°C or above this summer, setting another national record.
Wildfire Crisis Extends Beyond the UK
The wildfire threat is not confined to Britain.
In southern Spain, hundreds of firefighters have been battling one of the country’s deadliest wildfires in recent years in Almería province, where at least 12 people have died.
Four of the victims are believed to be British nationals.
The London railway fire and the growing number of wildfires across Britain have intensified concerns about how prolonged periods of extreme heat are increasing pressure on emergency services and infrastructure.
Authorities continue to urge residents to remain alert, follow evacuation advice when issued, and report any signs of fire immediately as hot and dry conditions persist.
