The Chesapeake & Ohio Railway commissioned American Locomotive Company to produce its 2-8-2 Mikado locomotives. Class K-3 units arrived in 1924 with road numbers 1210 to 1259, followed by fifty Class K-3a locomotives in 1926 numbered 2300 to 2349. Both classes feature 63-inch drivers, 28 x 32 cylinders, 200 psi boiler pressure, and 67,698 pounds of tractive effort.
These simulation locomotives differ slightly in tender specs and share a 338-square-foot firebox, 4,160 square feet of evaporative heating surface, and 5,663 square feet total with superheaters. Train enthusiasts recreate historical rail operations with these detailed K-3 and K-3a models on PC. Rail simulation fans who value precise locomotive specs find an authentic addition here.
The C&O turned to the American Locomotive Company to build it some 2-8-2 Mikado type locomotives
Class K-3, also delivered in 1924, assigned road numbers 1210 through1259 and fifty of the third class, delivered in 1926, designated as Class K-3a and given road numbers 2300 through 2349.
All had 63 diameter drivers, Class K-3 and K-3a had 28 x 32 cylinders, all had a 200 psi boiler pressure and the K-3 and K-3a locomotives exerted 67,698 pounds.
There were some differences between each of these classes including a different specification for tenders in each class. The Class 3 and Class 3a firebox was 338 square feet.
The evaporative heating surface was 4,160 square feet and with the superheater the combined heating surface was 5,663 square feet.
