They had parked a car nearby but approached the tracks on foot. No one else was in the car.
Schaffer said witness reports indicate the pair may have come close to the track but hesitated, then waited for a second train.
The train was on a north-south line and struck the couple at a crossing on Cherry Street. The train remained parked at the scene of the deaths for about three hours, Schaffer said. Both victims lived in Bluffton, according to police.
