Ralph Budd and the Burlington capitalized on the "Zephyr's" success. Many of the Burlington's named passenger trains began operating under the "Zephyr" brand. After the nine original "Zephyr" sets were completed during 1934-1938, standard production model diesel passenger locomotives with improved engines became available. Trains consisting of the new locomotives with new streamlined cars of standard size were ordered. Burlington ordered its new EMC E5 passenger diesels with matching stainless-steel fluting and operated their new full-size, long distance trains under the "Zephyr" brand, with perhaps the best known being the "California Zephyr.'
