Illinois Central 2-10-0 No. 3610 was a hybrid product of the railroad's Paducah Shops. This 325,000-pound Decapod was fashioned in 1939 using the frame of a 2-10-2 and the boiler of a 2-8-2. She had 30x32-inch cylinders and 225 p.s.i. of boiler pressure, and rolled on drivers 61½ inches in diameter. No. 3610 was sent to the torch in October 1955. This photo, by an unidentified photographer at an unknown location, comes from the collection of Gary Thompson.
