Train driver arrested after 7 killed in crash

Seven people were killed and more than 50 injured when a tram derailed while rounding a tight curve in a rainstorm in south London Wednesday, police said.

Investigators said the train, which tipped over on its side, apparently was going faster than permitted.

British Transport Police said several others were seriously injured in the accident.

Police arrested the 42-year-old tram driver on suspicion of manslaughter.
