Ocean View Branch



The Ocean View Branch was a railroad line between San Francisco and San Bruno, California. It was in use from 1863 to 1942, with some sections remaining until the 1970s. The right-of-way between Glen Park and San Bruno was reused for Interstate 280 and Bay Area Rapid Transit.

History
The San Francisco and San Jose Railroad opened south from San Francisco to San Francisquito Creek on October 23, 1863, and to San Jose in January 1864. It ran from a station at Temple (later 25th) and San Jose Street then wound southwest through the San Bruno hills of southern San Francisco. It turned south through Daly City and southeast at Colma, then paralleled El Camino Real through South San Francisco to San Bruno, California. By March 1967, trains were being run up Valencia Street to a new depot at Market Street. The company was acquired by the Southern Pacific Railroad (SP) in 1868. The railroad was not very useful to local residents in San Francisco: high fares discouraged both passengers and freight, and street running in the Mission District made the ride slow. Helper engines were required for the 3% grade at Oceanview in southern San Francisco. In 1878, the SP surveyed an alternate route east of San Bruno Mountain to bypass the line's grades and curves. The northern end was rerouted off of Valencia Street to Harrison, Division, and Townsend streets in the 1870s as the Southern Pacific had been granted land in the Mission Bay for a new terminal. Residents rejected a plan to double-track the railroad around 1900.

The United Railroads opened its San Mateo interurban between San Francisco and San Mateo in 1902. It paralleled the SP for its whole length and ran directly alongside the railroad between South San Francisco and Burlingame. It competed with the railroad for passengers, especially for traffic to the Colma cemeteries for which the SP had numerous flag stops.

On December 8, 1907, the SP opened its Bayshore Cutoff between San Francisco and San Bruno. The new cutoff was straighter and flatter than the old route: it reduced the maximum grade from 3% to 0.3%, the maximum elevation from 292 feet to 20 feet, and the San Francisco–San Bruno distance from 13.69 miles to 11.04 miles. With the cutoff thus saving 20 minutes in running time, most service switched to the new route. The old mainline between though points became the Ocean View Branch, also called the San Bruno Branch or San Bruno line. By 1913, more that two dozen daily round trips used the cutoff, with just 3–4 round trips over the Ocean View Branch. The SP planned to electrify the Ocean View Branch as an extension of the Peninsular Railway to compete with the San Mateo interurban, but never did so.

In June 1919, passenger service over the line was reduced to a single daily round trip. The SP was allowed to temporarily discontinue passenger service on the branch in November 1928 during a construction project. This became permanent in March 1930, though freight service continued. Plans were put forward in 1930 to integrate the line into a proposed rapid transit system with much of the route rebuilt as an elevated railway and a new segment north along Capp Street leading to Mission Street. The tracks were abandoned north of Ocean Avenue to 23rd Street on August 10, 1942, and south of Ocean Avenue to at least Daly City after a 1956 excursion train. Tracks had been taken up for scrap metal in World War II. The Southern Freeway (Interstate 280) was constructed partially on the abandoned right-of-way between Glen Park and Daly City in the 1960s. Bay Area Rapid Transit (BART) opened its San Francisco line in 1973, paralleling I-280 between Glen Park and Daly City.

Freight service on the Daly City–South San Francisco segment ended in 1978. From 1984 to 1988, BART constructed an extension south from Daly City to a new yard at Colma, partially along the former right-of-way. The Muni Metro J Church light rail line would be extended down San Jose Avenue through the Bernal Cut beginning in 1991. Colma station was added to the BART system in 1996. The 2003-opened extension to San Francisco International Airport and Millbrae was built in a tunnel under the abandoned right-of-way from Colma to San Bruno. Some rails remained in place until construction began on the extension, while other sections had been sold to adjacent cemeteries. The Centennial Way Trail opened in 2008 between South San Francisco station and San Bruno station. It uses the right-of-way of the Ocean View Branch and the parallel interurban.

Bernal Cut
The largest earthworks on the line was the Bernal Cut, which was originally excavated at 2700 ft in length and a depth of 43 ft. It was enlarged between 1928 and 1930 to include a streetcar line and extended San Jose Avenue when the railway was removed.
