No one hurt after train derails near Grande Cache

The Transportation Safety Board is investigating a freight train derailment in northern Alberta near Grande Cache.

Board spokesperson Roxanne Daoust says 25 rail cars and a locomotive that were part of a 102-car Canadian National train that was heading from Swan Landing to Grande Prairie left the tracks on Saturdayevening.

The cars were carrying fracking sand, which is used by the energy industry for hydraulic fracturing, and Daoust says it doesn't pose an environmental concern.

She says neither of the two-person crew were injured. Emile Scheffel with CN says the derailment happened on a branch line, and that railway crews would be working throughoutSundayto remove the damaged cars and fix the track.

Scheffel says there's no indication that a waterway has been affected.
