Subway train derails in London

LONDON, England (AP) -- A subway train derailed in east London during rush-hour Thursday. One person was injured in the accident, which police said was not related to terrorism.

The accident happened near Bethnal Green tube station in east London.

One passenger suffered an ankle injury when the Central Line train derailed at 9:04 a.m. local time, British Transport Police said.
Paramedics were attending the scene, but there were no immediate reports of further injuries. The accident was reportedly caused by an obstruction on the tracks, according to Transport for London.
Britain remains on alert following last week's attempted car bombings in London and a fiery vehicle attack in Glasgow. Authorities say the failed bombings bear all the characteristics of an al Qaeda operation. Watch as tube train derails in east London »
In July 2005, suicide bombers struck London's public transport system, killing 52 people.
Bob Crow, general secretary of the Rail, Maritime and Transport Workers union, said in a statement that subway workers had repeatedly raised safety concerns to transport authorities that contractors working in the area where the derailment occurred were not properly storing equipment.

The train remained upright throughout the incident, police said. Britain's Press Association reported six cars were believed to have gone off the track.
A total of 700 passengers were evacuated from the derailed train and the one stuck behind it, with the operation completed about two hours after the derailment, Transport for London said in a statement, adding that neither train was full.
Passengers walked out of the tunnel through the shortest route to either Mile End or Bethnal Green subway station, police said.
A large section of the Central Line was suspended.
The Rail Accident Investigation Branch was investigating the derailment.
There were 21 derailments on the system in the year ending March 31, but none of those trains was in passenger service, according to Transport for London.
British authorities are on high vigilance before the anniversary of the terrorist suicide bombings in London that killed 52 people on London's subway and on a bus, July 7, 2005.
