The C&O's 50 2-8-2s of class K-3a came from American Locomotive Company's Richmond works in 1926, and were all retired in the early 1950s. This heavy 2-8-2 design featured 28x32-inch cylinders, 200 p.s.i. of boiler pressure, and the customary Mikado 63-inch driver diameter. They weighed 353,000 pounds minus tender and developed a tractive force of 67,700 pounds. With a grate area of slightly over 80 square feet, they had 4461 square feet of evaporative heating surface and 1173 square feet of superheater surface. No. 2317 appears here at Toledo on June 18, 1950 in a pose captured by R. J. Foster. Most online photos of the K-3 class show them with the typical C&O Vanderbilt tenders, but images like the above reveal that a rectangular tender, perhaps from a retired C&O or Pere Marquette 2-8-4, was later substituted on some still-active members of this class.
