About 9:45 a.m., e.s.t., on January 2, 1982, eastbound Southeastern Pennsylvania transportation Authority (SEPTA) passenger train No. 114, consisting of a single rail diesel self-propelled passenger car (RDC), struck a southbound Atlantic Richfield Company (ARGO) tractor/cargo-tank semitrailer (truck) carrying gasoline at the Second Street Pike crossing at Southampton, Pennsylvania. The tractor and trailer overturned, erupted in fire, and crushed the rear of a automobile standing south of the crossing in the northbound lane of Second Street Pike. Five persons sustained minor injuries. The train operator sustained second and third degree burns over 80 percent of his body and died 2 weeks later as a result of his injuries. Damage was estimated at $452,900.
