Marylebone station was evacuated after a fire broke out in a train last night (Friday, December 11).
Around 500 people were cleared from the station concourse, and Melcombe Place was closed, after smoke was seen coming from a carriage.
Firefighters were called to the scene just before 9pm and spent two-and-a-half hours tackling the blaze.
London Fire Brigade said an air conditioning unit beneath one of the train's six carriage and a small part of the carriage itself had been damaged.
Station manager Paul Hobbs, who was at the scene, said: "The fire affected one of the train's carriages but crews worked quickly to put it out. Around 500 people were evacuated from the station's concourse before the brigade arrived."
Four fire engines, a fire rescue unit and around 25 firefighters attended the fire, the cause of which is under investigation.
