It was the third deadly wreck involving Amtrak in less than two months.

"They weren't supposed to be meeting like that, clearly," South Carolina Gov. Henry McMaster said. "It appears that Amtrak was on the wrong track." He said the CSX train seemed to be on the track it was supposed to be on. 

The wreck involving Amtrak Train 91, heading from New York to Miami, occurred at 2:35 a.m. in Cayce, S.C., about 10 miles south of Columbia, according to Derrec Becker of South Carolina Emergency Management.

The CSX train was parked on a side track when the Amtrak train slammed into it at about 59 mph, McMaster said. 

Lexington County Coroner Margaret Fisher identified those killed as Michael Kempf, 54, of Savannah, Ga., and Michael Cella, 36, of Orange Park, Fla. Kempf was the Amtrak engineer and Cella was the conductor, she said.
