RE:"there will have to be a significant loss of life"The new tankers to replace the DOT were thought to be puncture proof. Two derailments on the CP line near Canora Sk near Regina punctured mile or so from town. Onky a few cars burnt because they were carrying dilbit. If the DAPL is shut in there will be 500,000 bopd dIled. That was the crude at Lac Magantic. Were I live there is a unit train dilbit every day through the crow nest pass. CP has a branch line that runs about 400 feet from my house. Fortunately all the hual is sulphuric acid for Tecks smelter. Marner who believes politicians or gov't workers can get anything done, like our new environmental targets which will get kicked down the road until 2025. They couldn't find their way to the outhouse at night with a map and flashlight.
