The L&YR Class 24 was a class of short-wheelbase 0-6-0T steam locomotives of the Lancashire and Yorkshire Railway (L&YR). It was designed by Aspinall and introduced in 1897 for shunting duties. Twenty locomotives were built, but six were withdrawn between 1917 and 1922. They were the first locomotives on the L&YR built with Belpaire fireboxes.[3]
Design and construction
[edit | edit source]They were designed for use in freight yards with sharp curves and steep inclines where more power was needed than that provided by alternative 0-4-0ST Aspinall Pugs.[3]
This was the first time for a new build on the L&YR a Belpaire firebox was used.[3] The short-wheelbase design included outside cylinders with Richardson balanced valves on top; these being controlled by a combination of Allan motion and rocking shaft.[4] These locomotives – together with the Improved Precedent Class on the London and North Western Railway – were the last locomotives built with the Allan straight link motion.[5]
Modifications
[edit | edit source]The steam reversing gear, helpful for faster shunting operations, was later replaced by a screw which negated this effect. The push and pull regulator handle seemed to have been responsible for a number of minor accidents through lack of fine control was also replaced by a standard type. Those working in the Liverpool docks area had bells fitted beneath the boiler.[6]
Seven of the remaining engines were re-built with Barton Wright type round top boilers around the 1917–1919 period.[7]

Service
[edit | edit source]The class was allocated mostly to yards in the Liverpool area with Newton Heath and Agecroft depots receiving a number for use in their local larger marshalling yards. One based at Ormskirk was noted for performing on the main line between shunting duties.[2]
Fourteen locomotives passed to the London, Midland and Scottish Railway at the grouping in 1923.[9] After further withdrawals, 5 locomotives passed to British Railways (BR) in 1948 and they were numbered as shown in the table above.[10] All had been withdrawn by 1961.[8] None were preserved.
