"At least 18 times in the past three years BNSF Railway freight trains rolled west out of Minneapolis pulling cars filled with hazardous chemicals that were not on the train's official cargo list, according to train crew complaints.

That's contrary to federal regulation because in case of an accident, local firefighters can be left in the dark, unable to take quick action to protect vulnerable residents.

In one case, a train traveled more than 20 miles through the western suburbs with six carloads of anhydrous ammonia, a toxic corrosive gas used as a farm fertilizer, before the train crew knew the chemical was on the train, a complaint said. In another, a complaint said a train traveled about 90 miles west to Willmar before its cargo list — called a manifest — was corrected to show an extra car of ammonia."
