AS CRUCES, N.M. (AP) -- A Federal Railroad Administration spokesman says it could take several weeks to determine the cause of a deadly freight train derailment in southern New Mexico.
Three railroad employees were killed Saturday when the train's locomotive plunged 40 feet down a ravine.
Police have identified the three as 38-year-old Donald White, 60-year-old Steven Corse and 50-year-old Ann Thompson. White lived in Silver City, N.M., and Corse and Thompson lived in the northern Arizona community of Paulden.
No other people were on the train.
The derailment occurred near the community of Bayard, about 75 miles northwest of Las Cruces.
At least half of the train's eight cars tilted on their sides, but none of the iron ore being carried by the train spilled out.
The train was operated by Southwest Railroad Inc.
