North Dakota's booming energy business has been driven the use of rail transport. Today, over 61% of oil production from the region leaves on a railcar, and several producers, such as Continental Resources (NYSE:CLR) and Oasis Petroleum (NYSE:OAS)-- both of which ship over 80% of their production via rail -- have enjoyed price premiums for oil moving to East and West Coast refiners. Problem is, though, many of the rail lines in the region weren't built to handle this kind of capacity. This is leading to some major bottlenecks.

Find out what this could mean for oil producers in the region and why investors should be aware of this situation by tuning into the video below.
