APNewsBreak: Railroad in fiery derailment agrees to changes

BILLINGS, Mont. (AP) — The nation's largest freight railroad has agreed to more thorough inspections and maintenance improvements after a fiery oil train derailment in Oregon and the discovery of more than 800 potential safety violations across its sprawling network.

Details on the agreement between the Federal Railroad Administration and Union Pacific were obtained by The Associated Press.

Sixteen tank cars from a Union Pacific train hauling North Dakota crude through the Columbia River Gorge derailed in early June along a curve in the tracks near Mosier, Oregon. The accident sparked a massive fire that burned for 14 hours and prompted the evacuation of nearby areas.

No one was injured. But federal officials said the railroad wasn't following its own inspection rules to ensure the track was safe. A closer examination of the tracks would have caught a series of broken bolts that allowed the rails to move too far apart where the accident occurred, officials said.

The investigation into the accident is continuing.

The more than 800 potential violations against Union Pacific were found as part of a two-year examination of tracks across the U.S. used to haul crude. The violations include some of the same lax inspection problems blamed in the Mosier derailment, federal officials said. Enforcement actions against the company have not been finalized.
