Union Pacific #481 was built in 1902 as #1902 by Burnham, Williams & Co., in Philadelphia, PA, later part of Baldwin. It is one of an order for twenty Consolidation (2-8-0) type locomotives built as Vauclain compounds (#1901-#1920 renumbered #480-#499 in 1915). As built, the 1901s had 15½x 30 high pressure and
26x 30 low pressure cylinders. However, by the turn of the century, many US railroads were turning away from compounds and were converting those they owned to single-expansion locomotives. So, between 1910 and 1918, the 1901s were progressively simplified with 21x 30 cylinders, #437 in March 1910. The 1901s were based on the UP's 1640 Vauclain
compounds (you can see one of these on the UP 1640 #437 page of this website) but heavier, 192,670 lbs, 171,870 lbs on its 57" drivers, with boiler tubes lengthened by a foot and grates increased from 33.9 sq ft to 47 sq ft. With a 191.2 sq ft firebox and total heating surface of 2,584 sq ft, they operated at a boiler pressure of 200 psi, delivering 31,719 lbs tractive effort. train locomotive railway vehicle transport industrial machine industrial vehicle industrial machine
