There is such a oversupply problem in western Canada that the price/barrel dropped to $15 fob Alberta. All the pipelines are full. No more capacity. Therefore, the next option is to ship it by rail tanker cars via the CN or CPRS railroads. The railroads like this business because the whole train(like coal) starts in one place and never stops except for crew changes until it gets to the refinery destination. Then the empty train all goes back to where it started and repeats.
The problem results when the train derails in places like Lac-Mégantic, PQ on a Saturday night kills 50 people and burns half the town to the ground. That train was going from the Bakken Shale area to Irving’s refinery in St. John’s, NB. However, at least that only wasn’t transported in one of those dangerous pipelines like Keystone.(sarc)
