Eight fire engines and around 60 firefighters were called to a fire at Stratford train station.
The incident involved multiple seats of fire affecting trees, shrubbery, grass and some railway infrastructure near the railway tracks.
At 2200 hrs (10 July), the fire was declared under control by the Brigade. However, crews remained on scene through the night to dampen down hotspots and monitor for any flare-ups. The Brigade left the scene by 0700 hrs on 11July.
Station Commander Scott Thorpe, who was at the scene, said: "This fire was predominantly located within an area of grass and shrubbery that was surrounded on all sides by railway tracks. Crews also worked to extinguish other pockets of fire in around the station's sidings.
"The power to the railway tracks was isolated and the Brigade liaised closely with its multi-agency partners in order to resolve this incident safely.
"Firefighters worked hard to bring this fire under control as swiftly as possible; and we retained a presence through the night to ensure all areas had been fully extinguished."
Stratford station was safely evacuated and remained closed during the height of the incident.
Firefighters assisted the British Transport Police and other agencies to safely decant at least 1,400 passengers from a number of trains that were stopped near Stratford station.
This incident continues to cause major travel disruption to rail services today (11 July). National Rail is providing updates and travel advice to passengers on its website. Transport for London services have also been disrupted.
The Brigade received the first of around 40 calls at 1854 and Control Officers mobilised crews from Plaistow, Poplar, Ilford, Bethnal Green and surrounding fire stations to the scene. The fire was brought under control by 2200.
The cause of the fire is unknown at this time.
