Unlike most railroads that rostered the wheel arrangement, the Santa Fe did not call its 4-6-4s "Hudsons" but considered them an extension of the 3400 class of Pacifics. No. 3462, shown here at Kansas City in 1947, belonged to the AT&SF's second group of oil-burning 4-6-4s which came from Baldwin Locomotive Works in 1937. Having 84-inch drivers and developing 300 p.s.i. of boiler pressure, they had cylinder dimensions of 23½x29 inches. Their locomotive weight was 412,330 pounds (No. 3460, the only one to be streamlined, weighed more) and they exerted 48,618 pounds of tractive force. Grate area totaled 98.5 square feet, evaporative heating surface 4770 square feet, and superheating surface 2080 square feet.
No. 3461 of this class handled a train the entire 2,227-mile run from Los Angeles to Chicago in December 1937, setting a world distance record for a steam locomotive. No. 3463, preserved in Topeka, Kansas, is the subject of a proposal to restore it to operation using solid biofuel. The photographer who captured this photo of No. 3462 is not specified, but the image, which was saved from a long-discontinued Internet site, also appears in the Railfan.net ABPR Archive uploaded by Bud Laws.
