The 8F design incorporated the two-cylinder arrangement of the Black Fives. They were initially classified 7F, but this was later changed to the more familiar 8F. On the outbreak of the Second World War, the design was chosen to become the country's standard freight design, reprising the role the GCR Class 8K had in the First World War. The War Department had 208 8Fs built by Beyer Peacock and North British Locomotive Company and requisitioned 51 more. Stanier 8F production for the WD continued until 1943, when the cheaper WD Austerity 2-8-0 was introduced. Production for British domestic use continued until 1946. 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「LMS Stanier Class 8F」の詳細全文を読む スポンサード リンク
