A crowded Underground train failed to stop and smashed into the end of a tunnel in central London, killing the driver and 42 passengers.

The morning rush-hour Tube from Drayton Park in north London sped past the platform at Moorgate station and ploughed into the wall at the end of the tunnel.

The impact crushed the first three coaches of the train, squashing the first carriage to a third of its usual length.

It took over 13 hours for the last survivor, a City of London policewoman, to be rescued only after rescuers amputated her foot.

The cause of the accident, in which 70 where also injured, is still a mystery as there was nothing wrong with the train and the driver was in perfect health.

Nevertheless new safety measures were introduced to stop such an accident happening again.
