Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels, six coupled driving wheels and two trailing wheels. This arrangement is commonly called a Prairie. Other equivalent classifications are: * UIC classification: 1C1 (also known as German and Italian classifications) * French classification: 131 * Turkish classification: 35 * Swiss classification: 3/5 * Russian classification: 1-3-1 ==Overview== The majority of American 2-6-2s were tender locomotives, but in Europe tank locomotives, described as 2-6-2T, were more common. The first 2-6-2 tender locomotives built for a North American customer, were built by Brooks Locomotive Works in 1900 for the Chicago, Burlington and Quincy Railroad, for use on the Midwestern prairies. The type was thus nicknamed the Prairie in North American practice. This name was often also used for British locomotives with this wheel arrangement. As with the 2-10-2, the major problem with the 2-6-2 is that these engines have a symmetrical wheel layout, wherein the centre of gravity is almost over the center driving wheel. The reciprocation rods, when working near the center of gravity, induce severe side-to-side nosing, which results in severe instability if unrestrained either by a long wheelbase or by the leading and trailing trucks. Though some engines had the connecting rod aligned onto the third driver, like the Chicago and Great Western of 1903, most examples were powered via the second driver, hence the nosing problems remained with the type.〔Swengel, p. 79.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2-6-2」の詳細全文を読む スポンサード リンク
