But as White notes, the real change in passenger car construction was in weight, not the streamlined appearance that was largely for show: "Weight, not air friction, was the chief obstacle to economic operation." Unlike the heavyweights, the lightweight cars that debuted in the mid-1930s featured sides and roofs that contributed to their structural strength, eliminating the need for the heavyweights' massive underframes. Trucks went from six wheels to four, non-revenue space was decreased by using a vestibule on only one end of the car, and lighter, stronger, more rust resistant steel alloys came into widespread use. A typical new lightweight could be 15-20 tons lighter than the heavyweight car it replaced.
As with the diesel revolution that was simultaneously taking place, one of the key players in the changeover to lightweights was not an established industry name, but an upstart new player from the automotive industry: the Budd Company of Philadelphia, a supplier of auto body stampings. In 1928, Edward G. Budd had heard about stainless steel, a lightweight, rustproof metal introduced in 1912 by Krupp of Germany. Budd was the first to grasp the potential of stainless beyond cutlery and novelty items. The key problem was the inability of stainless steel to be fabricated with normal welding techniques. Budd's chief engineer, Colonel Earl J.W. Ragsdale, spent five years developing the key process needed to make stainless into a viable structural material: the patented Shotweld electric welding process.
Beginning with the Burlington's Pioneer Zephyr of 1934, gleaming Budd-built trains, constructed almost entirely of stainless, helped defi ne the look of the streamlined era to the American public - even on railroads like the Pennsylvania and Norfolk and Western that painted over the stainless with company colors. While other car builders such as Pullman countered with stainless-sheathed steel cars like the Southern Pacifi c's Daylights, they were forced to use rivets rather than welding for construction. In later years, the result was that Budd cars lasted almost indefi nitely, while the stainless-sheathed imitators were plagued with out-of-sight rusting under the sheathing.
