Even taking your #'s at face value, how much is 60% more GHG worth economically?
Consider that
some sources state that it costs about 2-3x the price to move oil via rail than pipelines, and failure rates of railcars are much higher than that of pipelines.
Consider also that we would need to build massive new infrastructure (probably many dedicated rail lines) in order to ship the amount of oil that pipelines ship a day.
If you're really talking about CO2 emissions with electricity, then GP_Matt makes a good point that your real enemy is coal power generation, not pipelines.
