| Here is another Alco-Schenectady built 2-6-6-0 Mallet configuration (although this website does not have that option for Alco's). Drury (1993) says that these locomotives were the beneficiaries of two updates to the Mallet design the railroad was already operating -- a leading truck to make it a better road engine and a mechanical stoker. They apparently served their purpose well because all but one went to the Denver & Rio Grande Western in 1947, from which they retired a few years later (1949-1951) as 3370-3375. Specifics - Class 210 (L-77), 55" drivers, 225 psi boiler pressure, 21x32" high pressure cylinders, 33.5x32 low pressure cylinders, engine weight of 361,000 lb, tractive effort of 70,456 lb. Unknown photographer and date is approximate. |
