St. Louis Union Station features a massive Grand Hall with a 65-foot barrel-vaulted ceiling
and stained glass windows. The 11.5-acre train shed was a stub-end terminal that was
the world's largest roof span at the time of its opening. At its peak, the station
was one of the world's busiest, hosting 22 different railroads. In the 1940s it handled
100,000 passengers a day.
The existing Gateway Transportation Center is three blocks to the southeast of
Union Station (one light rail stop).
