In 1893, No. 999 of New York Central predecessor New York Central & Hudson River Railroad became the first locomotive to exceed 100 miles per hour. When it ended its high-speed service on the Empire State Express it was relegated to more mundane tasks, and its 86-inch driving wheels were replaced by 70-inch drivers. After appearing at the Chicago Railroad Fair it was exhibited at other events and was retired from service in 1952. In 1962, No. 999 was donated to Chicago's Museum of Science and Industry where it is displayed today.
