The “4ft 6in” in the title referred to the diameter of the driving wheels – although the stated dimension was for the wheel centres – the nominal diameter including the tyres was . ==Design== The design featured a boiler pressed to delivering saturated steam to two cylinders connected by Joy valve gear to the driving wheels. They were an extended version of the 2234 class 2-4-0T locomotives, sharing the same boiler and wheelbase. In 1905 five of the 2-4-2T were rebuilt as 2-4-0T, which may have led to the latter becoming known as “Chopper Tanks”. The twenty locomotives delivered in 1889–1890 were fitted with condensing apparatus from new. 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「LNWR 4ft 6in Tank Class」の詳細全文を読む スポンサード リンク
