Panicked train passengers jump onto track after smoke fills carriage
Several people have been injured after a commuter train had to be evacuated when a workman's drill overheated.
Smoke was reported to have filled the carriage of the London Underground train at Dalston Kingsland on Wednesday morning.
After commuters reported "sheer panic and terror" at the east London station, firefighters extinguished the smoking drill battery by putting it in a bucket of sand.
London Ambulance Service said it was treating "a small number of patients for minor injuries".
Video from the scene shows passengers standing alongside the tracks and along the platform.
A man in a high-visibility jacket can be heard telling commuters "it was a small fire", and Deejay Robert K, who posted the clip, said smoke was causing "chaos".
A London Fire Brigade spokesman said: "Firefighters have dealt with a small incident on a train at Dalston Kingsland station this morning.
"A workman’s drill had overheated and started smoking. Firefighters extinguished the battery and placed it in a bucket of sand.
The station was evacuated. The Brigade was called at 0711 and the incident was over by 0744. Fire crews from Stoke Newington attended the scene."
A London Ambulance Service spokeswoman said crews were called at 7.36am to an incident at the station.
She said: "We sent four ambulance crews, a single responder in a car, an incident response officer and our hazardous area response team (Hart) to the scene.
"We are treating a small number of patients at the scene for minor injuries."
The Metropolitan Police in Hackney tweeted that there had been a "reported issue with electrics on the train in the station", but it has since been declared safe.
Hackney Council said on Twitter: "Train incident at Dalston Kingsland overground station. Several walking wounded. Police & LAS on scene. Plz avoid station & area".
London Fire Brigade in Hackney said crews from Stoke Newington were called to the incident.
Passengers told on Twitter of the "sheer panic and terror" on board the London Overground train.
London Overground told passengers there was no service between Canonbury and Stratford stations due to an "incident" at Dalston Kingsland.
Service later resumed with severe delays and Dalston Kingsland station reopened at about 8am.
Duncan Cross, Deputy Director of London Overground, said: "At around 7.14am today there was an incident involving a faulty drill that was being carried to work by a customer at Dalston Kingsland. The train was evacuated and the emergency services attended.
"We would like to apologise to customers who were on board and to our customers whose journeys have been disrupted."
