Derailment near Mile End station

Derailment of a London Underground Central Line train near Mile End station, 5 July 2007

On 5 July 2007 a westbound Central line train struck a roll of fire-resistant material which was lying on the track between Mile End and Bethnal Green stations. The first three bogies of the train were derailed and the driver applied the emergency brake, stopping the train after 148m. There were no serious injuries caused by the derailment, but 20 passengers received medical treatment. All 520 passengers were evacuated from the train along the tunnel to Mile End station. The derailment also caused some damage to the first two carriages of the train, to the track and to one signal.

The immediate cause of the incident was a roll of fire-resistant blanket, approximately 1.8m long, lying across one rail. The blanket had been stored in a passage the previous night and weighted down, but the wind from passing trains had caused it to unfurl and fall onto the line. There were four causal factors and four contributory factors related to the incident. The underlying cause was the lack of a comprehensive risk analysis being performed to support the use of fire-resistant blankets.

RAIB has made five recommendations as a result of this incident. These involve:

  • the training of staff
  • the storage of materials around an operational railway
  • the use of fire-resistant blankets
  • the effects of wind in the deep level tube system.


Response to recommendations:

  • RAIB will periodically update the status of recommendations as reported to us by the relevant safety authority or public body.
  • RAIB may add comment, particularly if we have concerns regarding these responses.
