In 1932 Ralph Budd met Edward G. Budd (no relation), an automotive steel pioneer who was founder and president of the Budd Company. Edward Budd was demonstrating his new Budd-Michelin rubber-tired rail cars built of stainless steel. Pneumatic-wheeled railcars never found popularity for actual service in the US — they tended to derail — but they demonstrated the successful construction of lightweight stainless steel unibody railcars. Some power-trailer car sets in that series articulated with Jacobs bogies shared between cars embodied the basic elements of car construction that would be used to build a lightweight streamliner train.
