The City of Los Angeles was a streamlined passenger train between Chicago, Illinois, and Los Angeles, California via Omaha, Nebraska, and Ogden, Utah. Between Omaha and Los Angeles it ran on the Union Pacific Railroad; east of Omaha it ran on the Chicago and North Western Railway until October 1955 and on the Milwaukee Road thereafter. The train had number 103 westbound and number 104 eastbound. This train was the top-of-the-line for UP, which marketed it as a competitor to the Super Chief, a streamlined passenger train on the Atchison, Topeka and Santa Fe Railway, and the Golden State, a streamlined passenger train jointly operated by the Rock Island and Southern Pacific railroads. Many of the train's cars bore the names of locales in and around its namesake city. History City of Los Angeles service began in May 1936 using the diesel-powered custom streamliner M-10002. It was the second of Union Pacific's diesel streamliners to the west coast, following the City of Portland that started service nearly a year earlier. Initial service consisted of five runs monthly. CNW / UP replaced that set with a fourteen unit full-sized train pulled by a three-unit set of EMC E2 locomotives in December 1937. Service frequency was doubled in July 1938 with the former City of San Francisco streamliner M-10004. That set was replaced in March 1939 with a full-size train pulled by two-unit EMC E3 locomotive set. After World War II service was expanded with additional trains until daily service was achieved in 1947. The UP scored a public relations coup in the mid-1950s when the City of Los Angeles was featured in two episodes of the popular television series I Love Lucy. Starting in 1955 the Milwaukee Road tracks were used in place of the Chicago and North Western between Chicago and Omaha. Actor Ronald Reagan often traveled on this train and even did a full-page print ad for it that appeared in the National Geographic magazine. In a cost-cutting move, the City of Los Angeles was combined with the City of San Francisco in 1960. City of Los Angeles service was terminated after Amtrak took over Union Pacific's passenger rail services on May 1, 1971. Amtrak operated several excursion services on the Los Angeles–Las Vegas segment from 1972 to 1976, ending with the short-lived Las Vegas Limited. From 1979 to 1997, Amtrak operated the Salt Lake City–Los Angeles (Ogden–Los Angeles
