Train crash mystery

Officials said that it would take some time to figure out the cause. At this point, nothing obvious stands out.
The tracks in that stretch of Bridgeport are relatively straight. The speeds could not have been excessive because the crash was centered between two closely-spaced stations, the Fairfield Metro and Bridgeport stations. Also, the tracks were recently installed and both trains were the new M8 cars.
Sen. Richard Blumenthal, in fact, credited the new cars with reducing the number and severity of the injured. He had toured the scene of the derailment just prior to the Saturday morning press conference.
