File- In this July 6, 2013 file photo, workers stand before mangled tanker cars at the crash site of the train derailment and fire in Lac-Megantic, Quebec, Canada. On the tranquil bank of the Columbia River in Vancouver, Wash., just across from Portland, Ore., regulators are weighing the fate of what could become the Pacific Northwest's largest crude oil train terminal: it would receive daily shipments of up to 360,000 barrels of oil via four trains a day rolling through iconic river communities and into the crowded Portland/Vancouver metro area, each train 120 cars and more than a mile long.
