PITTSBURGH, Pa. -- It's happened again. Another Norfolk Southern train has derailed, this time in Pittsburgh, Pennsylvania.
Authorities said Saturday's derailment was in the west end of the city.
Five cars jumped the tracks, although the cars were empty.
No one was hurt and no hazardous material leaked.
Satuday's incident comes about two months after a Norfolk Southern train derailed in East Palestine Ohio, about 50 miles northwest of Pittsburgh.
That derailment leaked hazardous chemicals and triggered an investigation of Norfolk Southern's safety practices.
