A CSX freight train that derailed in Washington has spilled hazardous material near a subway station and disrupted commuter rail and long-distance Amtrak passenger trains, authorities say.
The derailment of a CSX coal train on a railroad bridge in Ellicott City, Md., on August 20, 2012 was caused by a broken rail with evidence of rolling contact fatigue, the National Transportation Board (NTSB) has concluded.
