LOUISVILLE, Ky. (AP) — Sparks from a cutting torch ignited leaking vapors from a derailed train car and caused a fire that burned three workers and prompted the evacuation of a town near Louisville on Wednesday, a fire official said.

The blaze broke out shortly after 1 p.m. EDT. Workers were using a cutting torch or welder to separate two of the derailed cars, said Lt. Col. Rick Harrison, assistant chief with the suburban Buechel Fire Department.
