Union Station

Character-defining elements of Union Station which relate to its Beaux-Arts design and to its functional character as a union station include:

-the axial symmetry of its plan and the use of classical elements on a heroic scale;

-the spatial relationship between its main components, the domed central rotunda, the north and south wings, and the subgrade passenger tunnel;

-the classicism expressed in the combination of a monumental entrance with plainer, set-back wings;

-the monumentality of the main entrance, achieved by, a large, classically detailed arch, flanking columns, and dome above, the large ornate metal entrance canopy with the large arched window plus clock located behind;

-the form and detailing of the north and south wings, including: the arrangement of paired windows of decreasing height under a broad cornice, richly detailed ground-floor windows, and ornate, metal-framed canopies over secondary entrances

-the use of Tyndall limestone on the building's exterior

-the interior sequencing of spaces around a central atrium, with the route to the passenger tunnel and platforms behind;

-the passenger tunnel, a significant functional feature of a multi-track, through station;

-the platforms and train shed;

-interior views from the gallery over the rotunda;

-the Beaux-Arts decorative treatment of the principal interior public spaces, including railings, fixtures wainscoting, grilles, mouldings and finishes.
