The worst boiler explosion was recorded in 1922, when a Clinchfield Railroad articulated locomotive exploded in eastern Kentucky, somersaulting the entire 130-ton boiler more than 600 feet in front of the engine, embedding it in a highway overpass. Both crewmen were fatally scalded. The last was—surprisingly, in 1989—on a tourist railroad in Texas; the NTSB/FRA report blamed on poor training. Fortunately, both crew members survived.
