In the Whyte notation for the classification of steam locomotives by wheel arrangement, the is a Garratt articulated locomotive. The wheel arrangement is effectively two 2-8-0 locomotives operating back to back, with the boiler and cab suspended between the two power units. Each power unit has a single pair of leading wheels in a leading truck, followed by four coupled pairs of driving wheels, with no trailing wheels. Since the 2-8-0 type is sometimes known as a Consolidation, the corresponding Garratt type could be referred to as a Double Consolidation. A similar wheel arrangement exists for Mallet type locomotives, but is referred to as . Other equivalent classifications are: * UIC classification: 1D+D1 (also known as German and Italian classifications) * French classification: 140+041 * Turkish classification: 45+45 * Swiss classification: 4/5+4/5 up to the early 1920s, later 8/10 ==Overview== This Garratt wheel arrangement was somewhat common, especially for locomotives intended for freight service. The first locomotive was a single metre gauge locomotive built by Beyer Peacock in 1924 for the Burma Railways as their class GA.I. The second, and perhaps the better known, was the single Class U1 of the London and North Eastern Railway (LNER), built in 1925.〔 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「2-8-0+0-8-2」の詳細全文を読む スポンサード リンク
