The Long Beach Line was a major interurban railway operated by the Pacific Electric Railway between Los Angeles and Long Beach, California via Florence, Watts, and Compton. Service began in 1902 and lasted until 1961, the last line of the system to be replaced by buses. However, the Southern Pacific Transportation Company continued to operate freight on the tracks, as the Union Pacific Railroad still does between Amoco and Dominguez Junction, and in 1990 the Southern California Rapid Transit District opened the Blue Line light rail along the same right-of-way.
