SP Engineering Drawings
SP Engineering Drawings from the 1940's. These drawings are original Southern Pacific Railroad documents describing potential or actual changes in track layout created for the various engineering departments.
These plans are from my collection; the California State Railroad Museum in Sacramento also has a large collection.
Feel free to view and copy, but please attribute to "Collection of Robert Bowdidge" if you share these drawings.
