In 1871, an additional route from Los Angeles to Yuma was designated under the authority of the twenty-third section of the act to incorporate the Texas Pacific Railroad, which authorized the Southern Pacific Railroad Company to construct a line of railroad from a point at or near Techachapi Pass, by way of Los Angeles, to the Texas Pacific Railroad at or near the Colorado River, with the same rights and privileges, and subject to the same limitations and restrictions as were provided in the Atlantic and Pacific Act of 1866.[172] Ambitious Construction Program Because of the terms of the federal Act of 1866, it was necessary for the Southern Pacific to proceed steadily in its construction to the south. The first piece of road offered in satisfaction of the requirement for a minimum annual construction, was that from San José to Gilroy. Then came an extension to Tres Pinos, which ended, for the time being, building on the Northern Division. What happened was that the associates found the southern end of the San Benito Valley, in which Tres Pinos is located, relatively poor in traffic, and difficult to build in. Stanford visited the country personally, and found no business there, nor, in his opinion, any prospect of business. He accordingly shifted construction from the Tres Pinos line to the territory south of Goshen, and caused the Southern Pacific to build its next 20 miles in that section, expecting to connect with the San Joaquin Valley branch of the Central Pacific which ultimately came to Goshen in August, 1872. The Southern Pacific track reached Delano on July 14, 1873, Caliente on April 26, 1875, and Mojave on August 9, 1876. The stretch of 240 miles from Mojave to The Needles was not finished until June 22, 1883, but that to Fort Yuma was completed in 1877.
