ATLANTA — Authorities with Atlanta’s transit agency say one of its passenger trains collided with a man who was on the tracks who later died of his injuries.

Metropolitan Atlanta Rapid Transit Authority spokeswoman Alisa Jackson says the man, whose name wasn’t released, was struck by the train Wednesday morning near the Candler Park station.

Authorities said he was taken to Grady Memorial Hospital in Atlanta with head and arm injuries and was later pronounced dead.
