Probe opened into U.S. train crash


Officials opened an investigation Saturday into a rush-hour collision between two commuter trains that injured more than 70 passengers and severed a key rail link.

Train service in the busy Northeast corridor from New York City to New Haven, Connecticut, used by tens of thousands of commuters, was suspended indefinitely and will likely be snarled for days as officials seek to determine the cause of the crash.

Investigators from the National Transportation and Safety Board are focusing on a section of rail on the eastbound track going toward New Haven that was fractured at a rail joint.
