Since the early 1900s, Arizona has seen dozens of train derailments across the state.
On Wednesday, a massive fire and partial bridge collapse occurred after a freight train derailed while crossing a bridge over Tempe Town Lake.
In recent decades, derailments have been caused by flash floods and potential sabotage, including the mysterious Amtrak Sunset Limited derailment that resulted in one death and 78 people injured in 1995.
Here are several notable railway derailments that have occurred over the past 45 years in Arizona. Twelve bomb-laden box cars of a Southern Pacific Railroad freight train exploded after it derailed and caught fire 15 miles east of Benson on May 24, 1973.
Two crewmen were slightly injured after leaping from the caboose of the moving train when they saw flames shooting 30 feet from the right side of the freight cars with bombs, according to The Arizona Republicarchives.
