The town of Heimdal is located at Milepost (MP) 149.5 on the single main track of BNSF’s KO Subdivision, Twin Cities Division, and is located approximately 75 miles east of Minot, North Dakota. The initial derailment occurred at MP 153.9 followed by an ensuing general pile-up of cars at MP 149. The derailment occurred toward the rear of the train and five of the derailed cars ended up on their sides and one car (consist position 89) derailed but remained upright.
