Officials Begin Lifting Evacuation After Train Derailment

Preparations began Friday to allow thousands of eastern Tennessee residents to return to their homes after a CSX train car carrying hazardous material derailed and caught fire. On Thursday morning in Maryville, about 5,000 people within a mile-and-a-half radius of the crash site were evacuated, along with several businesses. Most received urgent knocks at their doors between midnight and 6 a.m. by emergency workers who told them they should leave immediately.
