I can't get behind it for this reason alone. A train car run off the tracks and may not even leak a drop and regardless can only leak so much. Our best long term option IMO.

Pipelines are monitored for leakage and any leak can be sectioned off via valves. Of all methods of oil transport from ships to rail to trucks to pipelines, pipelines are probably the safest. For example, far more oil was spilled by the Exxon Valdez in one incident (up to 750,000 barrels) than in the biggest Alaska pipeline leak (16,000 barrels). And then there's the Deepwater Horizon (~5 million barrels). Also, trains use existing tracks, many of which run through cities where accidents are more harmful than in rural areas (refer to the recent Quebec derailment carrying crude oil that killed 50 people). Unfortunately, there is no perfectly safe manner to transport large quantities of oil.
The environmentalists' major complaint about the Keystone pipeline is the production process to convert the tar sands to crude oil, not pipeline leakage. This won't change if the Canadians build a pipeline to Vancouver or ship it by rail elsewhere. As long as the Canadians continue to exploit this resource, the method of its transport isn't the issue. That said, the pipeline is probably the safest and cheapest method and would provide necessary jobs in the US for its construction, operations, and maintenance.
