About 450 London Underground rush hour passengers were stuck on a train for almost two hours and had to be led out along tracks after a power fault.
Passengers were led out of the tunnel by staff
Transport for London (TfL) said the Jubilee Line train stalled near Bond Street and staff were unable to get it back into the station.
The commuters were led out by Tube staff and police on Wednesday morning.
A TfL spokesman said it was "due to a power fault on the rails". There were 441 passengers on the train.
It stopped between Baker Street and Bond Street stations at about 0735 GMT and passengers were led out of the train at about 0945 GMT.
Alan Dolman, a housing accountant for Tower Hamlets Borough Council, got on the busy train at Baker Street station.
He said the passengers, many of whom were standing, were generally calm but were becoming distressed, hot and dehydrated by the time they were evacuated.
"Their first priority ought to have been towards the passengers, not the logistical issue of how to move the broken down train," he said.
Passengers had to evacuate from the front of the train and were helped along the 300-yard (274m) walk over sleepers and gravel by police and ambulance staff.
Gemma Slade, who was travelling to work in Mayfair, said: "When we stopped most of the lights went out but we weren't told how long we would be stuck.
"In the back of your mind you think 'what's happening ahead' and wonder about terrorist incidents - it all goes through your mind."
A TfL spokesperson said: "As the simplest means of getting passengers off a stalled train is to move it into the station, attempts were made to move it without success.
"When this did not work, the decision was taken to push forward the train with another train.
"The safety of passengers is our top priority and we apologise for any inconvenience that today's disruption caused."
