St. Louis Union Station Train Shed, 1820 Market Street, Saint Louis, Independent City, MO

Significance: St. Louis Union Station Train Shed was one of the last all enclosing train sheds built in the United States. The shed was the largest, covering an area of 378,000 square feet or the equivalent of eight football fields. Designed by engineer George H. Pegram, the shed was a continuous flattened vault of five bays supported by Pegram trusses resting on six rows of columns. It measured 600 feet wide x 630' long x 74 feet high and covered 32 tracks. At its peak during the Second World War, St. Louis Union Station and Train Shed handled nearly 100,000 passengers a day. In 1976, the station serviced only six trains daily. Since 1978, Union Station had no trains service and stood vacant. In the early 1980s developers succeeded in packaging an adaptive reuse scheme that secured enough capital to rehabilitate the station and train shed.
