CN rail cars derail, explode in Alberta

Thirteen CN rail cars carrying liquefied petroleum gas (LPG) and crude oil has derailed and exploded in Edmonton, Alberta.

The incident occurred in the middle of the night and prompted the evacuation of a small town, Reuters reports.

No injuries were reported though the area – about 80km west of Edmonton – is under a state of emergency.

The incident draws attention to concerns over oil transportation by rail. The Canadian government has tried to address these concerns by introducing new regulation on crude oil transportation.

Saturday's explosion comes after a similar, yet much deadlier, incident in Quebec killed dozens in July.

This is the third CN accident in three weeks, according to Reuters.
