With the "Empire Builder" in operation, Amtrak began re-equipping the remaining long-distance trains in the west. The second permanent Superliner train was the "Desert Wind", then a day train between Los Angeles and Ogden, Utah, which gained coaches on June 30, 1980. The "San Francisco Zephyr", a long-distance train on the traditional Overland Route between Chicago and San Francisco, followed on July 7, 1980; it received the first of the Sightseer lounges on January 6, 1981. Amtrak assigned Superliners to another long-distance train, the Los Angeles–Chicago "Southwest Limited", in October 1980. The "Southwest Limited", formerly the "Super Chief", traveled the same route as the "El Capitan", whose Hi-Level cars had inspired the design. The management of the Santa Fe, impressed by the design, permitted Amtrak to restore the name "Chief" to the train, and Amtrak renamed it the "Southwest Chief" on October 28, 1984. The "Chief" was the first train to receive Superliner II sleeping cars in September 1993.
