Local rail-borne transit in Los Angeles began with horsecars in 1874, evolving with cable-powered and later electric-powered passenger vehicles. Yellow Cars describes the principal local transit system in and around Los Angeles in the first half of the 20th century. The canary-colored local streetcars formed the inner-neighborhood lines between a vast rail network of main lines known as the interurban system, primarily the Pacific Electric Railway Red Cars, which spiderwebbed throughout Los Angeles County and into Orange, Riverside, and San Bernardino Counties. Rail tycoon Henry Edwards Huntington consolidated several independent lines into this great interurban empire. He sold it in 1910 to the Southern Pacific Railroad, keeping the Los Angeles Railway Yellow Cars. These evocative photographs illustrate travel during decades of change, progress, economic setbacks, war, and postwar retrenchment, when streetcar service was taken over by bus lines.
