On jointed 39 foot lengths of rail, the railroad spent a great deal of money on it's physical plant to ensure a smooth ride, amazingly it's 1930's technology.
A number of the Hudsons were streamlined for service on the 20th Century Limited, noted Industrial Designer Henry Dreyfuss was employed by the NYC to create a new image for the premeir train. As the pics show, the traditional steam engine is largely gone, replaced with art deco elements - check out the streamlined casing, 84" Scullin disc driving wheels, and sleek tender.
