An estimate that the Keystone pipeline will only replace approximately 20 miles of train per day, or approximately 6,100 semi trucks. It will not equal a continuous train. This is because it will be transporting heavy tar, which is difficult to pump through a pipe. Pumping lighter fuels would obviously increase capacity enormously, but that is not the case with the Keystone project, which will only move approximately 1 million barrels of heavy tar per day.
The only reason a properly-installed and maintained pipeline would leak is if it were sabotaged.
No method moves materials more reliably, safer, and with fewer incidents than a pipeline. Arguments against them is in the realm of the technically blunted, who can't understand how much better it is to move things through a stationary object than put it on a semi and have it hit the highway x 6000 plus times per day and ride alongside a DWI or other hazards. Those who are against pipe lines are usually against civilization in general, living "dances with wolves" fantasies as they text through stoplights while holding a Starbucks between their knees.
AND has anyone pointed out that Warren Buffet's trains would lose business to the pipeline?
