A CN Rail clean up crew was on the scene this morning after 11 cars jumped the track near the Northwood Pulp Mill at about 8:30 p.m. last night.
The cars were carrying lumber and pulp products and there were no injuries, CN Rail spokesperson Kelli Svendsen said.
Earlier this week, CN Rail advised customers it will be running shorter trains between Jasper and Prince George because of the effects the extremely cold weather can have on train braking systems.
Svendsen neither confirmed nor denied that the weather was a factor.
"Every relevant factor will be evaluated as part of the investigation," she said.
The road into Northwood was unaffected and the rail line was expected to reopen tonight.
