Seattle's Union Station was built in 1911 as the Oregon & Washington Railroad Station to serve the Union Pacific Railroad and Milwaukee Road. Located at the corner of South Jackson Street and Fourth Avenue South, just east of King Street Station in the Pioneer Square neighborhood, the grand Beaux Arts style building was designed by Daniel J. Patterson. The interior is dominated by a central barrel-vaulted waiting space and originally featured a small hospital at concourse level, a restaurant, ladies' waiting areas, and other amenities. With the rise of automobile and airplane travel passenger rail service to the station was discontinued in 1971 and the station sat largely idle until 1999 when an extensive renovation transformed the space into the headquarters of Sound Transit.

The poster pictured here celebrates the grand re-opening of Union Station, which, as of 2026, continues to serve as Sound Transit's headquarters. The grand hall is open to the public and often utilized as an event rental space. The Union Station renovation was the winner of the 2000 National Historic Preservation Award.
