A major fire in Walthamstow, East London, has forced the suspension of part of the London Overground Weaver line, with Network Rail warning that disruption could continue for several days while damaged properties and railway infrastructure are made safe.
The blaze broke out on Sunday along a railway embankment near the tracks, prompting a large emergency response involving around 125 firefighters. The fire spread quickly, damaging several nearby homes and affecting railway infrastructure between Walthamstow and Wood Street stations. As a result, train services between Walthamstow and Chingford have been suspended until further notice.
According to Network Rail, one property located beside the railway suffered extensive damage during the fire and must be secured before engineers can safely reopen the affected section of the line. Officials said passenger safety remains the priority while structural assessments and repair work continue.
A Network Rail spokesperson explained that trains cannot resume operations until the damaged property has been declared safe, meaning commuters should prepare for continued disruption over the coming days.
To help minimise the impact, a shuttle train service is currently operating between London Liverpool Street and Walthamstow, allowing passengers to continue part of their journeys. However, no Weaver line services are running beyond Walthamstow towards Chingford, and travellers are being encouraged to check before setting out.
The incident also forced the evacuation of several households on Sunday evening as firefighters battled the blaze. Waltham Forest Council confirmed that while many residents have since returned home, families whose properties were badly damaged have been offered temporary accommodation while recovery efforts continue.
Emergency services remained at the scene for several hours to ensure the fire was fully extinguished and to prevent further risks to nearby homes and railway infrastructure. Investigations into the cause of the fire are expected to take place once the area is declared safe.
The disruption comes as another rail-related incident continues to affect passengers elsewhere in East London. A separate fire near the railway in Stratford on Friday damaged vital signalling equipment, leading to ongoing delays and service reductions for Greater Anglia trains operating through the area.
Network Rail said engineers are working as quickly as possible to repair the damaged signalling systems in Stratford, although some services continue to operate with reduced frequencies. Passengers travelling through the station have been warned to expect busier trains and possible delays until repairs are completed.
With two separate fire incidents affecting East London’s rail network within days of each other, transport operators are urging passengers to allow extra travel time and monitor service updates before travelling.
Rail experts note that infrastructure located alongside residential areas can require additional safety inspections after major fires, particularly where structural damage to nearby buildings may pose a risk to passing trains. These assessments can take time, especially when engineers need to work alongside fire investigators and local authorities.
For thousands of daily commuters who rely on the Weaver line, the closure highlights how incidents beyond the railway itself can have a significant impact on transport across the capital.
Network Rail has not yet confirmed when full services between Walthamstow and Chingford will resume but says engineers are working closely with emergency services and local authorities to reopen the line as soon as it is safe to do so. Until then, passengers are advised to use alternative routes and expect continued disruption across parts of East London’s rail network.
