View Diary: The Keystone XL Pipeline: “Game Over”? (21 comments)

    claims that train derailments are more frequent than pipeline spills, but release less oil per spill.

    I think that's actually true.  One problem with Enbridge, which I've seen in other pipeline mishaps, is that the pipeline operators didn't believe they really have a spill when their warning lights come on, so they keep pumping oil right out the damaged pipeline.

    Train derailments are painfully obvious, but can involve large quanitites on occasion.  I tracked ethanol tank car detailments for awhile, and there were multiple occasions of 5-10 tank cars (over 100,000 gallons) breaking open during a single derailment.   There are some youtube videos, the flames are spectacular.

     I doubt if Tar Sands would burst into flames.  However, rail lines usually follow bottom lands, so train derailments spilling Tar Sands could happen in and near rivers, too.

    Orly, it isn't evidence just because you downloaded it from the internet.
