the following day. Lines The East Bay Electric Lines were originally designated mainly by the names of their principal streets. They received numbers for Bay Bridge service. The most significant changes occurred as the result of the removal of the Harrison St. bridge between Oakland and Alameda in December 1923, and the agreement with the Key System in March 1933, with the Bay Bridge plans in view, to abandon duplicating lines, on the basis of which company first served each area. The Oakland 7th Street Line carried the most passengers, with the Berkeley Shattuck Avenue Line being second. Patronage was at a maximum about 1920 and had declined by about half by the time of Bay Bridge operation. The SP seemed to prefer to have groups of their lines terminate at the same place. Three lines originally terminated at Thousand Oaks in Berkeley, two at 14th and Franklin in Oakland, and two at High St S. in Alameda. The IER had two lines terminate at Thousand Oaks and two lines at West Alameda. Berkeley, California St Line - Thousand Oaks station at the intersection of Solano and Colusa Avenues (Colusa Wye) in Berkeley, via Colusa, Monterey, private right-of-way, California, Stanford to the upper platform of the Oakland 16th St Station, thence to Oakland Pier. Terminated March 1933. Berkeley, Shattuck Ave Line (originally Berkeley Branch Railroad steam line) - Thousand Oaks station (Colusa Wye) in Berkeley, via Solano, private right-of-way, Northbrae Tunnel, Sutter, Henry, Shattuck (stopping at Berkeley Station), Adeline, Stanford to the upper platform of the Oakland 16th St Station, thence to Oakland Pier. Designated Line # 3 (local) and # 9 (express) for Bay Bridge service, re-routed direct to the bridge with no stop at Oakland 16th St Station. During Bay Bridge operation, the last train of the day (early morning) to leave San Francisco was extended from Thousand Oaks along the outer 9th St Line to Albany (San Pablo Ave) because there was no 9th St Line service at this time; this was the last IER service when terminated in July 1941. Berkeley, 9th Street Line - Thousand Oaks station (Colusa Wye) in Berkeley, via Solano, Jackson, private right-of-way, 9th Street to private right-of-way to Stanford to the upper platform of the 16th Street Station in Oakland, thence to Oakland Pier.
