Under the Whyte notation for the classification of steam locomotives, 2-10-0 represents the wheel arrangement of two leading wheels on one axle, ten powered and coupled driving wheels on five axles, and no trailing wheels. This arrangement was often named Decapod, especially in the United States, although this name was sometimes applied to locomotives of 0-10-0 "Ten-Coupled" arrangement. Other equivalent classifications are: ⁕UIC classification: 1E ⁕French classification: 150 ⁕Turkish classification: 56 ⁕Swiss classification: 5/6 ⁕Russian classification: 1-5-0 These locomotives were popular in Europe, particularly in Germany, and in Russia; British use of the type was confined to the period during and after World War II. In the United States, the 2-10-0 was not popular but was a favorite of a small number of railroads, mostly in mountainous terrain. The 2-10-0's main advantage was that five out of six of its axles were powered, meaning almost all the weight was available for traction rather than being distributed over pilot and trailing wheels. The long rigid wheelbase caused problems on tightly curved track, so blind drivers were the norm, either on the central axle, and/or on the second and/or fourth axles. Often lateral motion devices were attached to the leading drive axle. Wikipedia [ - ]
