| Beautiful 1940 Baldwin 4-8-4 getting ready to doublehead with another locomotive near Bensenville, IL. According to SteamLocomotives.com "Engines 203 and 231-240 used 105.5 sq ft (9.8 sq m) of circulators to supplement firebox heating surface instead of the 147 sq ft (13.65 sq m) of thermic syphons installed in the rest. These forty S-2s operated mostly as freight haulers from Bensenville to Council Bluffs, Iowa or St. Paul, Minn. Occasionally they'd hook up to the westbound Olympian if it trailed more than twelve cars." Specifics - 74" drivers, 285 psi boiler pressure, 26x32" cylinders, engine weight of 490,450 lb, tractive effort of 70,816 lb, retired between 1953-1956. Arthur B. Johnson photo |
