The Indianapolis Union Station was the first union station in the world, opening on September 20, 1853, by the Indianapolis Union Railway within the Wholesale District of Indianapolis, Indiana at 39 Jackson Place. A much larger Richardsonian Romanesque station was designed by Pittsburgh architect Thomas Rodd and constructed at the same location beginning in November 1886 and opening in September 1888. The head house (main waiting area and office) and clock tower of this second station still stand today.
