The establishment of America's transcontinental rail lines securely linked California to the rest of the country, and the far-reaching transportation systems that grew out of them during the century that followed contributed to the state's social, political, and economic development. When California was admitted as a state to the United States in 1850, and for nearly two decades thereafter, it was in many ways isolated, an outpost on the Pacific, until the first transcontinental railroad was completed in 1869.

Passenger rail transportation declined in the early- and mid-20th Century with the rise of the state's car culture and road system. It has since undergone something of a renaissance, with the introduction of services such as Metrolink, Coaster, Caltrain, Amtrak California, and others. On November 4, 2008, the people of California passed Proposition 1A, which helped provide financing for a high-speed rail line.

19th century The railroads enabled California's agricultural and mineral products to reach national and international markets, encouraging large-scale farming, mining, and the growth of related industries. Railroads made it feasible to transport perishable goods, such as citrus fruits, to distant markets, transforming California into an agricultural powerhouse.Richard J. Orsi, " 'The Octopus' Reconsidered: The Southern Pacific and Agricultural Modernization in California, 1865-1915." California Historical Quarterly 54.3 (1975): 197-220.

The ease and affordability of rail travel spurred mass migration to California, with cities like Los Angeles and San Francisco experiencing explosive growth. For example, Los Angeles's population quadrupled in the 1880s after the arrival of the Southern Pacific and Santa Fe railways. They promoted the founding and expansion of towns, as access to rail lines became a critical factor in urban development. Real estate speculation boomed, with new communities springing up along rail routes. California history teachers, "Immigration to California: 1850-1900" (2025)online

The completion of the transcontinental railroad in 1869 integrated California into the national economy, making the movement of people and goods between the East and West fast, reliable, and affordable. This connectivity attracted investment, encouraged migration, and allowed California’s industries to thrive on a national scale. Railroads made California accessible to tourists, promoting the state’s climate and scenery. The resulting influx of visitors further boosted local economies.Richard J. Orsi, "Railroads in the History of California and the Far West: An Introduction." California History 70.1 (1991): 2-11.

Background

The early Forty-Niners of the California Gold Rush wishing to come to California were faced with limited options. From the East Coast, for example, a sailing voyage around the tip of South America would take five to eight months, and cover some 18,000 nautical miles (33,000 km). An alternative route was to sail to the Atlantic side of the Isthmus of Panama, to take canoes and mules for a week through the jungle, and then on the Pacific side, to wait for a ship sailing for San Francisco.Brands, H. W. (2003), pp. 75–85. Another route across Nicaragua was developed in 1851; it was not as popular as the Panama option. (see ) During the 1850s the voy:Ruta de Transito through Nicaragua was another option. Eventually, most gold-seekers took the overland route across the continental United States, particularly along the California Trail.Rawls and Orsi, (1999) p. 5. Each of these routes had its own deadly hazards, from typhoid fever to cholera or Indian attack.Duke and Kistler, p. 9

Transcontinental links The very first "inter-oceanic" railroad that affected California was built in 1855 across the Isthmus of Panama, the Panama Railway.Otis, Fessenden Nott (M.D.). Isthmus of Panama: History of the Panama railroad; and of the Pacific Mail Steamship Company, Harper & Brothers, New York, 1867 pp. 15–16; 50–56.The Panama Railroad: 1865, 1868 & 1871 Certificates of Stock; an 1855 Newspaper Report of its Opening; 1861 & 1913 Maps; Early Harper's Engravings; and 1861 Schedule of Regular, Special and "Steamer" Trains. The Panama Railway reduced the time needed to cross the Isthmus from a week of difficult and dangerous travel to a day of relative comfort. The building of the Panama Railroad, in combination with the increasing use of steamships (instead of sailing ships) meant that travel to and from California via Panama was the primary method used by people who could afford to do so, and was used for valuable cargo, such as the gold being shipped from California to the East Coast.One ill-fated journey, that of the S.S. Central America, ended in disaster as the ship sank in a hurricane off the coast of the Carolinas in 1857, with an estimated three tons of California gold aboard. (see ) Another notable ship wreck was the steamship Winfield Scott, bound to Panama from San Francisco, which crashed into Anacapa Island off the Southern California coast in December 1853. All hands and passengers were saved, along with the cargo of gold, but the ship was a total loss.

California's symbolic and tangible connection to the rest of the country was fused at Promontory Summit, Utah, as the "last spike" was driven to join the tracks of the Central Pacific and Union Pacific Railroads, thereby completing the first transcontinental railroad on May 10, 1869 (before that time, only a few local rail lines operated in the State, the first being the Sacramento Valley Railroad).Daniels, p. 53 The 1,600 mile (2,575-kilometer) trip from Omaha, Nebraska, would now take mere days. The Wild West was quickly transformed from a lawless, agrarian frontier to what would become an urbanized, industrialized economic and political powerhouse. Of perhaps greater significance is the unbridled economic growth that was spurred on by the sheer diversity of opportunities available in the region.

The four years following the Golden Spike ceremony saw the length of track in the U.S. double to over 70,000 miles (nearly 113,000 kilometers).Daniels, p. 54 By around the start of the 20th century, the completion of four subsequent transcontinental routes in the United States and one in Canada would provide not only additional pathways to the Pacific Ocean, but would forge ties to all of the economically important areas between the coasts as well. Virtually the entire country was accessible by rail, making a national economy possible for the first time. And while federal financial assistance (in the form of land grants and guaranteed low-interest loans, a well-established government policy) was vital to the railroads' expansion across North America, this support accounted for less than eight percent (8%) of the total length of rails laid; private investment was responsible for the vast majority of railroad construction.Daniels, p. 55

As rail lines pushed further and further into the wilderness, they opened up huge areas. The railroads helped establish towns and settlements, paved the way to abundant mineral deposits and fertile tracts of pastures and farmland, and created new markets for eastern goods. It is estimated that by the end of World War II, rail companies nationwide remunerated to the government over $1 billion dollars, more than eight times the original value of the lands granted.Robinson, p. 157 The principal commodity transported across the rails to California was people: by reducing the cross-country travel time to as little as six days, men with westward ambitions were no longer forced to leave their families behind. The railroads would, in time, provide equally important linkages to move the inhabitants throughout the state, interconnecting its blossoming communities.

"Transportation determines the flow of population," declared J. D. Spreckels, one of California's early railroad entrepreneurs, just after the dawn of the twentieth century. "Before you can hope to get people to live anywhere...you must first of all show them that they can get there quickly, comfortably and, above all, cheaply."Dodge, p. 18 Among Spreckels' many accomplishments was the formation of the San Diego Electric Railway in 1892, which radiated out from downtown to points north, south, and east and helped urbanize San Diego. Henry Huntington, the nephew of Central Pacific founder Collis P. Huntington, would develop his Pacific Electric Railway in Los Angeles and Orange Counties with much the same result. Spreckels' greatest challenge would be to provide San Diego with its own direct transcontinental rail link in the form of the San Diego and Arizona Railway (completed in November 1919), a feat that nearly cost the sugar heir his life.Hanft, p. 77 The Central Pacific Railroad, in effect, initiated the trend by offering settlement incentives in the form of low fares, and by placing sections of its government-granted lands up for sale to pioneers.

When the Atchison, Topeka, and Santa Fe Railroad charted its own solo course across the continent in 1885 it chose Los Angeles as its western terminus, and in doing so fractured the Southern Pacific Railroad's near total monopoly on rail transportation within the state. The original purpose of this new line was to augment the route to San Diego, established three years prior as part of a joint venture with the California Southern Railroad, but the Santa Fe would subsequently be forced to all but abandon these inland tracks through the Temecula Canyon (due to constant washouts) and construct its Surf Line along the coast to maintain its exclusive ties to Los Angeles.Duke, p. 43 Santa Fe's entry into Southern California resulted in widespread economic growth and ignited a fervent rate war with the Southern Pacific, or "Espee" as the road was often referred to; it also led to Los Angeles' well-documented real estate "Boom of the Eighties".Donaldson and Myers, p. 58 The Santa Fe Route led the way in passenger rate reductions (often referred to as "colonist fares") by, within a period of five months, lowering the price of a ticket from Kansas City, Missouri to Los Angeles from $125 to $15, and, on March 6, 1887 to a single dollar.Duke and Kistler, p. 32 The Southern Pacific soon followed suit and the level of real estate speculation reached a new high, with "boom towns" springing up literally overnight. Free, daily railroad-sponsored excursions (complete with lunch and live entertainment) enticed overeager potential buyers to visit the many undeveloped properties firsthand and invest in the land.

As with the Comstock mining securities boom of the 1870s, Los Angeles' land boom attracted an unscrupulous element that often sold interest in properties whose titles were not properly recorded, or in tracts that did not even exist.Beebe, p. 240 Major advertising campaigns by the SP, Santa Fe, Union Pacific, and other major carriers of the day not only helped transform southern California into a major tourist attraction but generated intense interest in exploiting the area's agricultural potential.Rawls and Bean, p. 207 Word of the abundant work opportunities, high wages, and the temperate and healthful California climate spread throughout the Midwestern United States, and led to an exodus from such states as Iowa, Indiana, and Kansas; although the real estate bubble "burst" in 1889 and most investors lost their all, the Southern California landscape was forever transformed by the many towns, farms, and citrus groves left in the wake of this event.
