Dozens of firefighters are currently tacking a large blaze which has broken out in west London, causing disruption to trains including to and from Heathrow Airport.
Residents have been told to keep their windows and doors shut as six fire engines and up to 40 firefighters tackle a fire at an old coal depot in Tavistock Road, West Drayton.
Those using the Heathrow Express, as well as TfL rail and Great Western Railways services to Reading have been told to expect delays as services are resumed.
Fifteen people were evacuated from the scene shortly after the fire began at around 2pm. The cause of the blaze, which was accompanied by an explosion according to a witness, is not yet known. There are no reports of any injuries.
In a statement, the London Fire Brigade said that a “container, an industrial conveyor belt, 15 vans and three articulated lorries” are currently alight.
Station Manager Jon Holt, who is at the scene, said: “The fire is very visible and is producing a lot of smoke. Residents and businesses in the area should keep their windows and doors shut and drivers should avoid the area if possible.”
One eyewitness told the Mirror: “There were what looked like armed police in the street closing off the roads and getting everybody back – they all had all the proper gear on. There’s smoke everywhere, it was properly scary.”
