The Hammond Circus Train Wreck occurred on June 22, 1918, and was one of the worst train wrecks in U.S. history. Eighty-six people were reported to have died and another 127 were injured when a locomotive engineer fell asleep and ran his troop train into the rear of a circus train near Hammond, Indiana. The circus train held 400 performers and roustabouts of the Hagenbeck-Wallace Circus.
