Engineering Drawings

The PDF files below externally and internally arranged by geographic locality, ordered north to south in the case of multiple cities. Many of the originals were drawn in pencil from blank forms, from copies of earlier drawings, or simply by erasing and drawing over earlier data. They were not colorized - only the subsequent copies made from them were hand-colored for specific purposes. Note that most these drawings were created for proposed construction, some of which never took place. Content variously includes both "maps" and floor plans.

Robert Bowdidge's site on Flickr hosts 170+ of them. Robert, friend and kindred spirit, also believes that such valuable (and cool!) data ought to shared, not sat upon. By coincidence, Robert lives near Wx4 Summer Headquarters and out-bid us on eBay for his collection. We outbid him for ours. Small world. He also has a fine website that includes extensive hisories of Santa Clara County packing companies / modeling SP's Vasona Branch / his Blog

"Clear Standing Room" (car capacity) Diagrams

These diagrams were referenced by rookie yardmasters to determine the car capacity on any given rail. Of course, any guy holding a yardmaster tag and worth his salt knew the REAL track capacities, and that these charts were "all wrong". Nevertheless, they're interesting snapshots-in-time of Coast Division terminal trackage, especially the San Jose maps when compared to the SPINS Zone Maps shown elsewhere.
