Unlike other stations in town, Union Station's design included plenty of ornate characteristics and a prominent, three-story clock tower. The 110-foot tower served ostensibly served as a downtown skyscraper, immediately noticed by those coming to and from Springfield, Il. However, the town decided to remove the clock hands in 1936 while in the midst of the Great Depression; the cost of maintaining the clock proved too expensive. Immediately following World War II, the tower was removed down to its base.
Union Station ceased to exist as a functional passenger train center in 1971 when Amtrak came into town -- Amtrak moved into the former Gulf, Mobile and Ohio station, located about three blocks west of Union Station. As a result, notably after a $12.5 million renovation in 2007, Union Station became part of the Abraham Lincoln Presidential Library and Museum complex. The renovation project included restoring the 110-foot clock tower.
