- —History of the Union Station[src]
The Union Station was opened in 1885 by the Gentlemen's Association of Ohio Land Owners. It was built following the American Civil War after the Glenn's Hill Military Hospital, which had previously been in its place, was razed in 1864. With the Union Station being built in its honor, it was intended to serve as a betterment of trade and travel for all and was in active use until the fall of society in 2010.
At some point in the apocalypse, Union Station was inducted into the Commonwealth, presumably serving as transportation between the civilization's territories, as well as a historic landmark at the heart of the main town.
Union Station is shown as a bustling train terminal with many Commonwealth residents and visitors coming and going from the station. In addition to rail services, the offices for the city's Communications and Legal offices can be found on the second floor and the city's Security department can be found on the first floor.
