This map depicts the network of electric rail lines operated by Southern Pacific in Oakland, Alameda, and Berkeley, during the period from 1923 to 1932, before the Bay Bridge railway opened in 1939. The map includes two insets and written historical notes about this now-vanished rail system that was formed from railroads that had been constructed in the East Bay starting in the 1860s.
