Terrified Tube passengers were stuck on a carriage which was rapidly filling with smoke for three-and-a-half minutes.
An official report into the accident at Holland Park Station on 25 August says that while the main doors were still shut, some passengers tried to squeeze out by opening the side doors between carriages.

Despite the panic, no one was injured. However the Rail Accident Investigation Branch said:
"There was potential for injuries to occur because the train was heavily loaded and a large number of people were prevented from leaving the train for almost four minutes after it stopped."
