 Five cars of a CSX freight train derailed in Fredericksburg last night. Authorities say no one was hurt when the cars left the tracks near the Virginia Railway Express Station around 9 o'clock last night. Several cars at a nearby apartment complex in the Cobblestone neighborhood were damaged. There was apparently some hazardous material aboard the train, but it was not in the cars that jumped the tracks. That material has been fully contained. CSX now trying to figure out what caused that derailment.
