The London and North Western Railway (LNWR) Claughton Class was a class of 4-cylinder express passenger 4-6-0 steam locomotives.

They were introduced in 1913, the first of the class No. 2222 was named in honour of Sir Gilbert Claughton, who was the Chairman of the LNWR at that time. 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. [1]

The LNWR reused numbers and names from withdrawn locomotives, with the result that the numbering was completely haphazard.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 engine, 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.[2] 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 At the end of 1939, all but one, 6004, had been withdrawn. The Second World War caused such a motive power shortage however that 6004 soldiered on in terrible condition on local freight duties in the Wolverhampton area. Acquired by British Railways in 1948, it was allocated the BR number 46004 but was withdrawn in 1949 without it being applied. None was preserved.
