The San Pedro, Los Angeles & Salt Lake Railroad was completed in 1905, linking Salt Lake City to southern California. U.S. Senator William Andrews Clark was the majority owner of the railroad, which was a corporation based in Utah. Among its original incorporators were Utah's U.S. Senator Thomas Kearns and his business partner David Keith. Kearns, one of the richest and most powerful men in Utah, and Keith were the owners of Utah's Silver King Coalition Mine, several mines in Nevada and "The Salt Lake Tribune" newspaper. Kearns and Keith helped Clark ensure the success of the new railroad across Utah and into Nevada to California. Curiously, for a time there were two towns named Las Vegas. The east-side of Las Vegas (which encompassed the modern Main Street and Las Vegas Boulevard) was owned by Clark, and the west-side of Las Vegas (which encompassed the area north of modern-day Bonanza Road) was owned by J.T. McWilliams, who was hired by the Stewart family during the sale of the Las Vegas Rancho and bought available land west of the ranch. It was from their property that Las Vegas took form.
