NTSB Finds Water On Rails At Ill. Derailment Site

The agency has conducted initial interviews with the train's crew, and investigators are looking for witnesses, Sumwalt said.

"We want to reach out to the people who might have witnessed something before, during or immediately after the derailment," Sumwalt said.

Canadian National Railway Company officials say 18 rail cars loaded with ethanol left the tracks, exploding into flames. Zoila Tellez, 41, of Rockford, abandoned her car at a rail crossing and made it 20 feet before she fell and died.

A 17-year-old girl injured in the accident was in critical but stable condition Sunday at the burn unit of Chicago's Stroger Hospital, said spokesman Marcel Bright.
