This 15-minute walking tour guides you through the history of Union Station, which goes back as far as 1914 and chugs through the golden age of railway travel in the United States into the present. It points out the iconic building’s architectural highlights along the way, and answers some common questions, like: Why was it built? How was it used? Why was it nearly abandoned, who saved it from decay, and what do we mean by “modular monument” anyway? The tour starts at the east side door, nearest the Streetcar stop, and takes you through a gallery of historic construction photos into the Grand Hall and Grand Plaza. There’s also a balcony viewing point that most visitors never see.
