At approximately 8:00 p.m., mountain standard time, on January 27, 1997, Apache Railway train APA No. 81 derailed 46 cars, 2 miles south of Holbrook, Arizona. The 46 cars were part of a 78-car train. The crew was removing one car from the train when the remainder of the train rolled down a 1.7-percent descending grade, finally derailing on a 6 degree curve. Two tank cars derailed. One tank car containing hydrogen peroxide was compromised and released its entire contents. A fire ignited in the wreckage; it was generally confined to cars containing waste paper. Local emergency responders evacuated 150 people from a nearby residential area until the morning of January 28, 1997. There were no fatalities or injuries. Damages were estimated at $2.06 million.
