BNSF Railway, the largest hauler of crude oil from North Dakota, said Monday that it has cut the speed of Bakken oil trains through the Twin Cities to 35 miles per hour as a voluntary safety step.
U.S. railroads have run oil trains at no more than 40 mph through Minneapolis, St. Paul and 45 other "high threat" U.S. cities under a 2014 agreement with the U.S. Transportation Department.
BNSF said that as of last Wednesday it dropped its maximum Bakken oil train speed another 5 mph and applied the limit to all cities of 100,000 people or more. That means Fargo, N.D., which BNSF's oil trains pass through on their way into Minnesota, will be covered by the speed limit. The city is not on the "high threat" cities list.
No other cities in Minnesota or North Dakota are covered by the BNSF limit. Federal transportation officials separately are working on new oil train regulations for all carriers, including standards for more robust tank cars.
"We are not going to wait anymore," BNSF spokesman Mike Trevino said in an interview. "We are going to slow train speeds down further still because that will improve safety until we have a tank car that is appropriate for that commodity."
BNSF has supported more robust tank cars, most of which are not owned by railroads. Trevino said oil trains will continue to run at up to 50 mph in less populated areas.
A BNSF oil train derailed and caught fire near Galena, Ill., on March 5, in the latest in a series of accidents involving Bakken crude oil.
BNSF has told state officials that 37 to 52 oil trains each week enter Minnesota at Moorhead. Each train carries at least 1 million gallons of Bakken crude oil. Most go through the Twin Cities, then on to Wisconsin.
