Transit matters in Sunnyside. In the 1890s, one public transit line was the impetus for the founding of the neighborhood, the San Francisco and San Mateo Electric Railway. Until the 1940s the Southern Pacific steam train barreled along the eastern edge of the district. In the 1960s, construction of the I-280 freeway forever changed the neighborhood.
