Los Angeles and Salt Lake Railroad
The Los Angeles and Salt Lake Railroad (reporting mark SLR) was a rail company that completed and operated a railway line between its namesake cities, via Las Vegas, Nevada. Incorporated in Utah in 1901 as the San Pedro, Los Angeles and Salt Lake Railroad, the line was largely the brainchild of William Andrews Clark, a Montana mining baron and United States Senator. Clark enlisted the help of Utah's U.S. Senator Thomas Kearns, mining magnate and newspaper man, to ensure the success of the line through Utah. Construction of the railroad's main line was completed in 1905. Company shareholders adopted the LA&SL name in 1916. The railway was also known by its official nickname, "The Salt Lake Route," and was sometimes informally referred to as "The Clark Road." The tracks are still in use by the modern Union Pacific Railroad, as the Caliente and Lynndyl Subdivisions.
The development of the railway line that became the LA&SL began in 1871 when the Utah Southern Railroad began laying track southward from Salt Lake City. The Utah Southern, controlled by the much larger Union Pacific Railroad (UP), built a line to a station known as Juab, Utah in 1879. From there a second UP subsidiary known as the Utah Southern Railroad Extension took up the work, completing trackage as far as Milford, Utah in 1880. By the end of the century, these and other lines had been absorbed into the Oregon Short Line Railroad, a far larger UP subsidiary.
Work on extending the Milford line southward began by 1889, but no tracks were actually laid due to financial issues. Construction resumed in 1899 when the route was completed as far as the Utah-Nevada border. Grading work extended into Nevada, and the UP's stated intent was to continue the line all the way to southern California.
Another player entered the scene in 1900, however, when William Andrews Clark acquired the struggling Los Angeles Terminal Railway with an eye to extending the line northeast to Salt Lake. The railroad was reincorporated in 1901 as the San Pedro, Los Angeles & Salt Lake Railroad and Clark announced plans to construct a line between Salt Lake and southern California. Clark assembled political and financial supporters to assist in the project, both in California and Utah; the competing Union Pacific Railroad and its formidable leader E. H. Harriman stood in opposition to Clark's plan.
Clark's forces began construction work in Nevada, along the existing UP grade, and a brief "railroad war" ensued before Clark and the UP called a truce in 1903. Their agreement called for Clark's railroad to acquire the existing UP trackage south of Salt Lake City; in turn, the UP received a 50% ownership interest in Clark's railroad. Construction of the remaining line proceeded rapidly, and the complete Salt Lake-Los Angeles line was opened on May 1, 1905. In California Clark negotiated a trackage rights agreement allowing his new line to use the existing Atchison, Topeka and Santa Fe Railway route over Cajon Pass, in lieu of constructing its own tracks across the pass.
On April 16, 1916 the railroad's stockholders voted to remove "San Pedro" from the corporation's name; the former town of San Pedro had been consolidated with the city of Los Angeles in 1909. The LA&SL operated independently until April 27, 1921 when the UP agreed to acquire Clark's half-interest in the railroad. After 1921 the LA&SL lines were operated as part of the UP system, although the LA&SL corporation continued to exist on paper until January 1, 1988. The former LA&SL main line remains part of the UP network today as the Caliente and Lynndyl Subdivisions.
In 1925 LA&SL reported 1158 million ton-miles of revenue freight and 192 million passenger-miles; at the end of that year it operated 1208 miles of road and 1970 miles of track.
Route and stations 
Following standard railroad practice, the LA&SL designated a series of locations along its route as "division points" -- bases for the railroad's operational and maintenance activities. Traveling southwestward from Salt Lake, the railroad's division point towns were Lynndyl, Utah; Milford; Caliente, Nevada; Las Vegas; Yermo, California; and San Bernardino, California. The railway also maintained a substantial presence in the remote town of Kelso, California. Nearly the entire route of the railroad traversed rugged and largely unpopulated desert terrain. There were no major population centers between the railroad's endpoints until the city of Las Vegas began its rapid growth in the mid-twentieth century.
The LA&SL was known for its depot buildings, many of which were imposing structures in the Mission Revival architectural style. The largest such depot, at Milford, was razed in 1979, but landmark LA&SL stations in Caliente and Kelso survive today. Several smaller Mission Revival depots erected by the railroad still exist in southern California. At least two of the railroad's smaller stations, at Lund and Black Rock, Utah, were designed by the noted architect Gilbert Stanley Underwood. The Salt Lake City depot was built in the French Renaissance style and is a landmark in that city.
