41241 storms into Oxenhope on a service from Keighley, 20th October 2007. At the end of the Second World War the London Midland and Scottish Railway were in desperate need of a modern small tank engine to replace numerous pre-grouping engines on branch line and secondary passenger duties. Chief Mechanical Engineer H G Ivatt developed a 2-6-2T design with incorporating modern labour safing devices such as self-emptying ashpans and rocking grates. Construction began in 1946 and ten were built by the London Midland and Scottish Railway before nationalisation in 1948, and were numbered 1200–9. A further one hundred and twenty were built by British Railways (41210–329) between 1948 and 1952. All but the last ten (built at Derby works) were built at Crewe works. 41241 was built by British Railways at Crewe and entered traffic in September 1949, allocated to Bath Green park MPD. It was withdrawn seventeen years later in December 1966. It was sold to the Keighley and Worth Valley Railway in 1967 and moved from Skipton, from where it had been withdrawn to Keighley under its own power. 41241 hauled the train at the reopening of the branch line in 1968 and has become synonymous with the KWVR ever since
