Truck carrying gas hits railroad bridge and explodes as a train passes overhead

A tractor-trailer loaded with what authorities believe were gas containers slammed into the bottom of an overhead railroad bridge in upstate New York and exploded Thursday night as a freight train was traveling on the tracks above. At about 6:30 p.m, the truck hit the bridge in Glenville, about 30 miles (48 kilometers) northwest of Albany. Police said the driver apparently failed to heed signs warning that the height clearance was 10 feet (3 meters).
