Several people have been injured after a workman’s drill overheated and sparked a small fire on a packed commuter train.
Firefighters were called to Dalston Kingsland station in east London where they extinguished the drill’s battery pack and placed it in a bucket of sand.
The blaze reportedly sent smoke billowing through the carriage, which was abandoned at around 7.10am.
London Ambulance Service said it was treating “a small number of patients” at the scene for minor injuries.
Footage from the station showed commuters standing alongside the tracks, while a man in a hi-vis jacket could be heard telling passengers “it was a small fire”.
One passenger said there was “sheer terror and panic” on the train.
Another said: “I was on the train and everyone jumped onto the tracks it was horrific.”
A tweet by London Overground said it was believed a customer’s battery had “exploded” in the carriage, but a spokesman said this was under investigation.
In a statement, deputy director of London Overground Duncan Cross said: “We would like to apologise to customers who were on board and to our customers whose journeys have been disrupted.”
The station was reopened at 8.15am, but London Overground warned of severe delays on the entire route between Richmond and Stratford and Clapham Junction to Willesden Junction.
