'Absolutely staggering' damage
The damage to the tracks and several train cars is "absolutely staggering," said Sen. Richard Blumenthal of Connecticut, who visited the site with other officials Saturday. Wreckage littered an area of about 200 yards.
"Ribbons of the sides of cars are torn away like ribbons of cloth," the senator said. "Tons of metal tossed around like toy things. The insides of cars are shattered."
The two Metro-North passenger trains, heading in opposite directions, collided Friday evening in southwestern Connecticut. The train heading from New York City to New Haven derailed around 6:10 p.m. and struck the other train in Bridgeport, Connecticut, Weener said Saturday.
Both trains were traveling at about 70 mph immediately before the crash.
