BNSF train spills 230K gallons of crude oil into river
Excessive rainfall that washed out a portion of the track was one of the factors in a June 22, 2018 train accident that released more than a quarter of a million gallons of crude oil into the Little Rock River, according to the National Transportation Safety Board (NTSB).
An update released by the agency on its investigation into the Lyon County, Iowa derailment – which prompted the evacuation of 18-20 people from the area – does not name a cause.
