In June 2016, a broken bolt sent a Union Pacific train carrying volatile crude oil hurtling off the tracks in the Columbia River Gorge, spilling 42,000 gallons (158,987 liters) and forcing the evacuation of the nearby town of Mosier, Oregon, United States. The accident was caused by at least one broken bolt holding the rail in place, according to a report filed by the company with the Federal Railroad Administration.

The broken bolt, which is unique to curved sections of track, failed despite the train traveling at 26 mph (42 km/h) in a 30 mph (48 km/h) zone. As a result of the accident, Union Pacific checked similar bolts in curved sections of its 32,000 mi (51,499 km) of track across 23 states. The company also replaced bolts in the derailment area with heavier duty ones and increased inspections in the Columbia River Gorge from once every 18 months to four times a year.

The derailment, which caused no injuries, raised concerns about the risks associated with transporting crude oil by rail.
