These original locomotives were described as “poor performers” . They suffered coal consumption as high as 100 pounds per mile plus mechanical problems causing very poor reliability. Around the time of their construction, they were nicknamed ''"Dreadnoughts"'' on account of their large size, after the then-new Royal Navy battleship . ==Rebuilding== As designed, they were fitted with a saturated boiler, slides valves and Joy valve gear. In 1919–20, fifteen were rebuilt with superheaters, piston valves, Walschaerts valve gear and slightly larger cylinders. The nominal tractive effort of the rebuilds was which made these engines for a time the most powerful in Great Britain until 1922 when the Gresley pacifics appeared. The rebuilt locomotives were reported to be "a good workmanlike engine" and "an engine thoroughly master of its work", although still with a coal consumption on the heavy side. 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「L&YR Class 8」の詳細全文を読む スポンサード リンク
