The train driver died after two trains collided on the Riverside Line in Newton, near Boston, just hours after an elevated train derailed in Chicago.

One train was stopped at a red signal and was ready to roll to the station when it was hit from behind.

Seven passengers were taken to local hospitals, and one was airlifted to a Boston hospital, officials said. About 10 passengers were injured.

The medical crews were unable to free the driver in time to provide medical help to the woman, identified as 24-year-old Terrese Edmonds.
