Under the Whyte notation for the classification of steam locomotives, 4-4-4 represents the wheel arrangement of four leading wheels on two axles, four powered and coupled driving wheels on two axles, and four trailing wheels on two axles. In the United States, this arrangement was named the ''Reading'' type, since the Philadelphia and Reading Railroad was the first to use it. In Canada, this type was known as the ''Jubilee''. Other equivalent classifications are: UIC classification: 2B2 (also known as German classification and Italian classification) French classification: 222 Turkish classification: 26 Swiss classification: 2/6 ==Usage== A single, experimental 4-4-4, classified as S 2/6, was built for the Royal Bavarian State Railway Company in 1906 by the firm of J.A. Maffei. It was successful in an experimental sense but was too light to haul passenger trains of useful capacity. It was fast, attaining on test, and was semi-streamlined with a pointed nosecone and fairings around the cylinders, stack and dome, and slanted-back cab windows. It inspired the later Bavarian S 3/6 4-6-2 "Pacifics". It passed to the Deutsche Reichseisenbahnen when the German railways were centralised, and was classified as BR 15, number 15 001. It was taken out of service in 1925, and was restored by Maffei to be exhibited at the Munich Transport Exhibition of that year. After the exhibition ended, it was placed in the Nuremberg Transport Museum, where it remains. 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「4-4-4」の詳細全文を読む スポンサード リンク
