St. Louis Train Shed
"The Train Shed, 11.5 acres of sweeping arches, was the largest single-span Train Shed ever constructed. George H. Pegram was selected to design the Train Shed that is attached to the the Headhouse, using his patented truss in 1891. The Train Shed covered the original 32 tracks leading into St. Louis Union Station. It measures 140 feet tall, 700 feet long by 600 feet wide. The roof system is a series of five Pegram trusses combined to form a gigantic arch. At it's peak, there is a skylight that is 36 feet wide, that was originally covered with glass. Construction started July 7, 1892 and finished in November 1893. The Train Shed was extended another 180 feet in 1904. With the increase in train travel, in 1929, ten more tracks were added to the west. It wasn't logical to add another Pegram truss to the side and throw off the symmetry of original Train Shed. Instead, they built an umbrella-type covering, that you can see along 20th Street.
The Train Shed and Headhouse were designated a National Historic Landmark in 1970." This paragraph was taken from the St. Louis Missouri Union Station website.
