A Green Line trolley derailed this morning at Huntington and South Huntington Avenue in the Mission Hill neighborhood, but no one was injured, officials said.
The trolley derailed at about 9:30 a.m., the Boston Fire Department said in a tweet. The intersection is a place where the tracks make a sharp turn.
Joseph Pesaturo, a spokesman for the Massachusetts Bay Transportation Authority, said in an e-mail that "a trolley wheel slipped off the rail.''
He said it was an "inbound two-car E Line train.'' He said there were 24 passengers on the trolley cars at the time of the derailment.
