A total of 130 were built, all at Crewe works up to 1921. Author Brian Reed points out that weight restrictions and equipment limitations at Crewe limited the size of the boiler, hence engine power. Cylinder design and valve events were not optimal, so the Claughton Class was a mediocre performer on the track. 〔 Reed, Brian, 1970, Locomotives - A Picture History, p58〕 The LNWR reused numbers and names from withdrawn locomotives, with the result that the numbering was completely haphazard. An exception was made for the LNWR's war memorial locomotive, 1920 - built ''Patriot'', which acquired the number 1914 from a Renown Class locomotive. The LMS renumbered them into the more logical series 5900–6029, no. 1914 becoming 5964. Twenty were rebuilt by the LMS with larger boilers, and ten of these had Caprotti valve gear. Twelve others were rebuilt as the initial engines of the LMS Patriot Class, though not much material was reused. From 1927 with the introduction of the LMS Royal Scot Class, the Claughtons' main work had been taken away and many were transferred to the Midland Division. At the end of 1937, all but four, nos. 5946, 6004, 6017 and 6023, had been withdrawn. These were retained in service until further repair became unworthwhile; three of them were withdrawn in 1940–41, leaving no. 6004 which was regularly used to haul fitted freight trains between London and Edge Hill, becoming increasingly dirty. Inherited by British Railways in 1948, it was allocated the BR number 46004 but was withdrawn in 1949 without it being applied. None were preserved. 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 Claughton Class」の詳細全文を読む スポンサード リンク
