I was wondering if anyone on this list<br>knows where we in Caltrans (State of <br>California, Department of Transportation), <br>District 4 (San Francisco Bay Area)<br>might find Key System engineering drawings <br>from the 1920's and 1930's. I am looking<br>on behalf of some of our engineers, who <br>need the information for the seismic <br>retrofit work that is going on now.<p>What I am looking for specifically is:<p>original drawings (plans) for the "Mole Substation", which is at the east end <br>of the Bay Bridge.<p>That building was built by the Key <br>System in 1926, to supply power to start<br>a number of streetcars moving at the same<br>time, which the Yerba Buena Island <br>Substation could not do alone. It was<br>originally called the "Pier Substation", <br>and later named the "Mole Substation". <br>It is owned by Caltrans.<p>I work for the men & women who inspect<br>the 7 state-owned toll bridges, and we <br>have many, many microfilmed engineering<br>drawings, but we do not have ANY Key<br>System engineering drawings, which <br>surprised me. We do, indeed, have many<br>drawings from the many private companies<br>which have contracted with the State of <br>California to do work of various sorts.<p>Here is a list of the organizations whose on-line catalogs I have already looked at.<br>and came up empty-handed:<p>1. Caltrans HQ Library in Sacramento, including the History Section.<br>2. University of California and "Cal State" library catalog, by using the "MELVYL"<br>on-line catalog (This includes the <br>Bancroft Library catalog.)<br>3. California Historical Society<br>4. California State Archives<br>5. Library of Congress<p>I have also talked to people in these organizations and found that they did <br>not have any Key System engineering<br>drawings (they did not know where any<br>might be):<p>1. Bay Area Electric Railroad Association (Western Railway Museum)<br>2. California State Railroad Museum<br>3. AC Transit<br>4. San Francisco Municipal Railway<br>5. Railway & Locomotive Historical Society<p>The last mention I can find of any Key System engineering drawings is on one of our<br>drawings for the construction of the Bay Bridge. Back in 1938, the Bay Bridge had an<br>office in San Francisco, on Sansome Street, in the heart of the financial district, and they had quite a number of Key System<br>drawings there. After then, I have no idea where they went.<p>I hope one of you knows if any Key System drawings exist.<p>I have also posted this question to the<br>Society of American Archivists listserv,<br>and to Trainorders Western RR Forum.<p>Good luck!<p>Margaret Monroe<p>Office Technician (Typing)<br>California Deapartment of Transportation<br>District 4<br>Structure Maintenance, Room 10-400<br>111 Grand Ave.<br>Oakland, CA 94612<br><br>
