Southern Pacific Sacramento Shops Car Shop No. 3, which began as an extension of the Planing Mill, saw drastic changes in function throughout its existence. By the time the shop closed in 1999, the building was a mixture of materials and designs from two centuries. The eastern wall was the original 1872 masonry that survived the 1916 fire. The sections created by the addition of fire walls had each been modified to create entirely different spaces in an area that was once 15 identical bays. Altered support structure, windows, and extensions demonstrate how changing needs affected the building’s architecture. Check out our page of plans and photos.
