The Great Train Wreck of 1918 occurred on July 9, 1918, in Nashville, Tennessee, United States. Two passenger trains, operated by the Nashville, Chattanooga and St. Louis Railway ("NC&StL"), collided head-on, costing at least 101 lives and injuring an additional 171. It is considered the worst rail accident in U.S. history, though estimates of the death toll of this accident overlap with that of the Malbone Street Wreck in Brooklyn, New York, the same year.
