Freight Train Derails On Flooded Tucson Tracks

A Union Pacific train derailed north of Tucson near Interstate 10 on Tuesday afternoon, officials said. Flooding caused by heavy rains contributed to the derailment, which occurred on the east side of the I-10 frontage road between Twin Peaks and Marana roads, according to posts on Twitter by the Marana Police Department and Northwest Fire District. The crash closed the frontage road, but I-10 remained open, although the Arizona Department of Transportation said backups were starting to occur on the interstate in the area late in the afternoon. Northwest Fire District officials posted video of the derailment on Twitter.
