The Budd Company built the "Pioneer Zephyr" for Burlington, and the train's "dawn-to-dusk" run from Denver, Colorado, to Chicago, Illinois, on May 26, 1934, in an unprecedented thirteen hours and five minutes, helped usher in the railroad streamliner era. Both Ralph and Edward Budd, among other notable men including H. L. Hamilton, president of the Winton Motor Company which built the motor for the train, were passengers aboard the record-setting run; the train's speed averaged 77.1 miles per hour (124.1 km/h), reaching a top speed of 112.5 miles per hour (181 km/h). The name of the new train came from "The Canterbury Tales," which Ralph Budd had been reading. The story begins with pilgrims setting out on a journey, inspired by the budding springtime and by Zephyrus, the gentle and nurturing west wind. Ralph Budd thought that would be an excellent name for a sleek new traveling machine: "Zephyr." In the summer of 1939 he persuaded the Denver and Rio Grande and the Western Pacific to join the Burlington in establishing a daily through train to the Pacific Coast; a decade later it was replaced by the fabled California Zephyr.
