Legally and technically, this comprehensive system was divided into five parts. The original Central Pacific Railroad ran from 5 miles west of Ogden to Sacramento. In 1870 this company consolidated with the Western Pacific Railroad, operating between Sacramento and San José via Stockton, the San Francisco, Oakland and Alameda Railroad, which connected the Western Pacific with the city of Oakland, the San Joaquin Valley Railroad branch from Lathrop to Goshen, and the California and Oregon Railroad, which left the main line of the Central Pacific near Roseville, and ran in a northwesterly direction to Redding toward the Oregon boundary. All these lines were directly under one operating control. A second important part of the system was the California Pacific between Sacramento and Vallejo, with a branch from Davis north to Marysville, and another from Napa Junction to Calistoga. The ownership of the third portion was vested in the Northern Railway. This company had been chartered in 1871, and had projected a line from Woodland, on the California Pacific, to Tehama, of which 82.20 miles were completed in 1875. In 1878 the company built from Oakland to Martinez, and from Benicia to Suisun, and still later it constructed a line from Benicia to Fairfield. This last bit of road enabled Central Pacific trains to run from Sacramento to San Francisco via Benicia, instead of passing through Vallejo. The San Pablo and Tulare, completed about the same time as the road from Oakland to Martinez, connected the Northern Railway with Tracy on the main line of the Central Pacific. The fourth part of the Huntington-Stanford system was the Northern Division of the Southern Pacific Railroad from San Francisco through San José to Soledad and Tres Pinos. The Tres Pinos line has been referred to in the previous chapter. The extension from Gilroy to Soledad up the Salinas Valley was in operation by 1877, and formed the first part of the route which later became the coast route to Los Angeles. The fifth and last part of the system was the Southern Division of the Southern Pacific Railroad from Goshen to Mojave, Los Angeles, and Yuma, with branches from Alcalde to Huron, and from Los Angeles to Wilmington. In addition to the main groups mentioned, there were certain minor extensions, such as the railroads from Sacramento to Shingle Springs (the Sacramento Valley and Placerville Railroad), from Stockton to Milton (the Stockton and Copperopolis Railroad), and from Peters to Oakdale (the Stockton and Visalia Railroad).
