The Southern Pacific 2-10-2’s were general purpose locomotives and were used system wide. The stand out news story about this class of SP loco was that in 1922 twenty 2-10-2’s were shipped from Baldwin in one train across the country and that train was called the Prosperity Special. The F4 and F5 class had 63 inch drivers, 29”x32” cylinders, weighted 397,900 lbs. and had a boiler pressure of 200 lbs. F-4 #3680 is modeled by Accucraft as it appeared in 1953 after a shopping and had a 16,000 gal semi Vanderbilt tender added. F-5 #3765 is modeled as it looked in 1955 with a clam shell stack and semi Vander built tender. The #3765 was one of the last 2-10-2’s to be shopped. Both these engines represent the Zenith of the 2-10-2 class on the Southern Pacific. The 2-10-2’s were very popular on the SP and could go places that the bigger Cab Forwards could not. Many of the 2-10-2’s were based on the SP’s Shasta Division and were used as the main power on the original main line to Oregon from California over the Siskiyou mountains.
