The incident was reported about 9:30 a.m. A Union Pacific representative told the news site in an email that cars on two trains had derailed near Sinclair, and that there were no injuries.

Carbon County Fire Chief John Rutherford told a Cowboy State Daily correspondent that the derailment stemmed from the “catastrophic failure” of a wheel bearing on a tank car. Most of the tank cars carried a fuel additive not listed as hazardous, Rutherford said, that had already started to evaporate. Sinclair, about 7 miles east of Rawlins, Wyo., on UP’s Laramie Subdivision, is the home of a major oil refinery for the company of the same name.
