28th February 1975: 43 killed in Moorgate rush-hour Tube crash
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.
