TORONTO, July 4 (Reuters) - A Canadian National Railway train carrying crude, gravel and lumber derailed near Whitecourt, Alberta early on Friday morning, the town's fire chief said.
Six cars on an 81-car train were laying on their side, Whitecourt fire chief Brian Wynn told Reuters, adding that there were no leaks or fires.
About 20 emergency crews were on site following a call about the derailment around 5:40 a.m. local time, Wynn said.
The Transportation Safety Board said it has deployed an investigator to the site.
CN Rail officials could not immediately be reached for comment. (Reporting by Solarina Ho; Editing by Jeffrey Hodgson and Sandra Maler)
