The Norfolk Southern Train, loaded down with coal, was going about 20 mph when it struck the car-dragging it more than a quarter mile before coming to a stop.
Stacey Jones tells Eyewitness News he was late for work when he heard the screeching noise of a train from his home nearby.
He says he found 22-year-old Crystal Higgins and her fiancé 25-year-old Brannon Brady unresponsive in the mangled Cadillac, nearby was an empty car seat.
"I saw a couple of bags laying on the ground, looked over there and I saw the baby," Jones said. "(He was) just kind of lying there. He moved a little bit once I picked him up. He cried a little bit, and I checked him to see if he had a pulse and he was still breathing.
Authorities say it appears the Cadillac was leaving a residence when it was struck on the passenger side by a long eastbound freight train.
There is no crossing arm at the intersection where the train hit the car.
