Is Bakken crude oil more explosive than other types of crude? This question is being explored by the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration after BNSF's recent train derailment and explosion outside of Fargo, N.D. Light sweet crude from the Bakken Shale was involved in three terrific explosions in 2013, leading authorities to test the flammability of the oil. 

While more scrutiny and negative public opinion are cast upon crude-by-rail transportation, TransCanada (NYSE:TRP) and other crude producers are hoping more pipeline capacity is approved to move the crude. The most contentious project is currently the northern portion of the Keystone XL pipeline, which is still being reviewed by President Obama. While crude-by-oil accidents are rare, the magnitude of the rare explosions might open the door for more pipeline operators in both the United States and Canada.
