September 22, 2015 | Grand Forks Herald | SCOTLAND, S.D. — Two days after a 98-car train carrying ethanol partially derailed, no cause has been determined, and officials say an investigation may take up to one year.
Terry Williams — public affairs officer for the National Transportation Safety Board — said the investigation began Sunday, but there are no solid leads. The National Transportation Safety Board is conducting the investigation.
“We are at the beginning of this investigation in the very early stages,” Williams said.
