When 
                          Amtrak took over the Santa Fe’s “Super Chief” train, 
                          it originally retained the name of the classic silver 
                          streamlined service. In 1974, the name was changed from 
                          “Super Chief” to “Southwest Limited”, a name it retained 
                          for 10 years before becoming the “Southwest Chief”.
                        Like 
                          the Super Chief, the Southwest Limited was made up of 
                          a mixture of ACF, Pullman and Budd-built stainless steel 
                          cars, the same basic consist as the original Santa Fe 
                          Train. Like the Santa Fe had done before it, Amtrak 
                          combined the ex-Super Chief and ex-El Capitan Hi-level 
                          cars in its Southwest Limited service, the single-level 
                          cars being used as the 1st class portion of the consist.
