Graham, Anderson, Probst & White, Union Station is one of the last grand
American railroad stations. When it opened in 1925 it was considered an
outstanding achievement in railroad facility planning. The limestone-clad
structure has an austere Neo-Classicism exterior with a massive colonnade on
the east side. The interior features a Beaux-Arts style Great Hall, a
marble-sheathed waiting room enclosed by colossal fluted Corinthian columns
with gilded capitals.
GP has designed many renovations to this historic structure, including the renovation and expansion of Amtrak’s first class lounge, replacing building systems and providing air conditioning to the Great Hall, replacing windows, and modernizing elevators. The most recent renovation project is the replacement of the famous marble staircases leading into the Great Hall from Canal Street.
