ACCIDENT TYPE: Derailment (DRM)
LOCATION: Culbertson, MT
RAILROAD: BNSF Railroad Co. (BNSF)
SUBJECT: Accident Investigations
ABSTRACT: (consist positions 79 through 100), at milepost 167.2 on the Glasgow Subdivision of the BNSF's Montana Division. Twenty cars derailed on their sides with one leaning against the signal case at milepost 167.24 and two cars derailed in an upright position. The derailment site is located approximately 46 miles west of Williston, North Dakota and approximately 6 miles east of the town of Culbertson, Montana. Train U-TNDAWA0-10T consisted of two leading locomotives, 106 loaded crude oil tank cars, two buffer cars, and two Distributive Power (DP) locomotives located on the rear of the train. The train had 14,963 trailing tons and was 6,702 feet in total length. Five of the derailed tank cars were breached and leaked a total of 27,201 gallons of product. A BNSF HAZ-MAT team responded to the accident and contained the spilled product with earthen dams. No water ways were affected by the spilled crude oil. Due to the spilled crude oil an evacuation order was issued by the Culbertson Fire Department for an area within a two mile radius of the accident site. This led to the evacuation of approximately 50 people (approximately 6 homes and an oil field workers residence camp). The evacuation was lifted at approximately 8:00 a.m. on July 17, 2015.
