According to CN, 18 train cars fully loaded with coal jumped the tracks on Dec. 21, 2011 approximately 10 kilometres East of Vanderhoof.
No one was hurt in the derailment but the accident resulted in delays to several other freight trains as well as a Via Rail East bound train.
All Via Rail passengers were subsequently bussed from Smithers to Prince George.
CN crews had the tracks re-opened by 7:15 a.m. on Dec. 22, 2011. A CN spokesperson said that the coal that spilled did not end up in any body of water and there is no impact to the environment.
The accident is now under investigation.
