Re: Lower Cascade Bridge

Be careful in using mileposts of any era on SP Lines. In 1869 Milepost "Zero" was at Sacramento. By 1874 mileposts were measured from San Francisco freight depot at 4th street via Niles and Stockton. By 1887 distances were measured from SF 4th street via Antioch to Sacramento. In 1890 they were measured from SF via Suisun to Sacramento. In the 1901-1904 period of line changes the distances east of Reno were measured via Hazen and in 1912 Milepost "0" was made the apron on the Ferry slip in San Francisco. I gave the CSRM an almost complete set of station books from 1879 to 1973 which could be of some help. Lynn
