Hagenbeck-Wallace circus in 1917 The Hammond circus train wreck occurred on June 22, 1918, and was one of the worst train wrecks in US history. Eighty-six people died and another 127 were injured when a locomotive engineer fell asleep and ran his train into the rear of another near Hammond, Indiana.
The Wreck
In the early morning hours of June 22, 1918, Alonzo Sargent was operating a Michigan Central Railroad troop train pulling 20 empty Pullman cars. He was aware that his train was closely following a slower circus train. Sargent, an experienced man at the throttle, had slept little if at all in the preceding twenty-four hours. The effects of a lack of sleep, several heavy meals, some kidney pills, and the gentle rolling of his locomotive are thought to have caused him to fall asleep at the controls.
At approximately 4:00 am, he missed at least two automatic signals and warnings posted by a brakeman of the 26-car circus train, which had made an emergency stop to check a hot box on one of the flatcars. The second train plowed into the caboose and four rear wooden sleeping cars of the circus train at a rail crossing known as Ivanhoe Interlocking (5½ miles east of Hammond, Indiana) at an estimated speed of 35 miles per hour.
The circus train held 400 performers and roustabouts of the Hagenbeck-Wallace circus. Most of the 86 who were killed in the train wreck perished in the first 35 seconds after the collision. Then, the wreckage caught on fire. Among the dead were Arthur Dierckx and Max Nietzborn of the Great Dierckx Brothers, a strongman act, and Jennie Ward Todd of The Flying Wards. There were also 127 injuries.
