Too early to say what caused Canada train crash -investigator
OTTAWA Jan 9 (Reuters) - It is too early to definitively say what caused the partial derailment of a Canadian train carrying crude oil and gas on Tuesday, the lead investigator said on Thursday.
Guy Laporte of the Transportation Safety Board also told a briefing that a broken rail had been found at the site of the accident in the eastern province of New Brunswick. One of the cars involved had a broken wheel set, he said.
