There is oil to be moved. Obama and company keeps delaying approval of the Keystone XL. So Warren Buffet and his railway the BNSF (and other railways) are stepping up and building thousands of miles of new track.
Right through the middle of cities.
BNSF will make the following investments:

-$26 million to add sub sidings to address congestion from Fargo, N.D., to Grand Forks, N.D.
-$14 million to add sub sidings to address congestion from Fargo, N.D., to Glendive, Mont.
-$13 million to add sub sidings to address congestion from Minot, N.D., to Grand Forks, N.D.
-$13 million to add sub sidings and an interchange track to address congestion from Canada to the U.S.
-$11 million for centrailized traffic control to improve service from Bismarck, N.D., to Fargo, N.D.
