The L&YR Class 24 was a class of short-wheelbase 0-6-0 T 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 Twenty locomotives were built, but six were withdrawn between 1917 and 1922.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 notable for being the first design of a locomotive on the L&YR to use a Belpaire firebox. [3]
They were designed for use in freight yards with sharp curves and steep inclines where more power was needed than that provided by alternative 0-4-0 ST 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]
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]

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 [10] All had been withdrawn by 1961.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.
George Hughes was an English locomotive engineer, and chief mechanical engineer (CME) of the Lancashire and Yorkshire Railway (L&YR) and the London, Midland and Scottish Railway (LMS).
Henry Albert Hoy (1855–1910) was a locomotive engineer with the Lancashire and Yorkshire Railway (L&YR). Hoy was born on 13 January 1855 in London, and educated at King Edward VI's Grammar School in St Albans, and at St John's College, Liverpool University.
The Lancashire and Yorkshire Railway Class 5 were 2-4-2T steam locomotives designed by Chief Mechanical Engineer (CME) John Aspinall and introduced from 1889 for local passenger work. Later batches included progressive modifications such as extended coal bunkers and Belpaire fireboxes. The final batch built from 1911 to 1914 under George Hughes incorporating superheated boilers gave increased tractive effort, others were also rebuilt to this standard. When Hughes introduced his classification system in 1919, the more powerful superheated locomotives were designated Class 6. The final examples were withdrawn in 1961.
The L&YR Class 21 is a class of small 0-4-0ST steam locomotive built by the Lancashire and Yorkshire Railway for shunting duties. They were nicknamed Pugs.
The Lancashire and Yorkshire Railway Class 27 is a class of 0-6-0 steam locomotive designed for freight work on the Lancashire and Yorkshire Railway (L&YR).
The Lancashire and Yorkshire Railway (L&YR) Class 23 is a class of 0-6-0ST steam locomotive. Their main use was for shunting and for short-trip freight working.
The LMS Northern Counties Committee (NCC) Class Y was a class of 0-6-0T steam locomotives formed when two LMS Fowler Class 3F engines were regauged from 4 ft 8+1⁄2 instandard gauge to the 5 ft 3 in Irish broad gauge in 1944 becoming NCC Nos.18 and 19.
The Lancashire and Yorkshire Railway Class 28 was a class of 0-6-0 steam locomotive, designed by George Hughes for the Lancashire and Yorkshire Railway (L&YR). It was a rebuild of Aspinall's Class 27, with the addition of a Belpaire firebox and the extension of the footplate and front sandboxes. It was similar, but had larger cylinders and a superheater. It had 5-foot-1-inch (1.549 m) wheels.
The Lancashire and Yorkshire Railway (L&YR) Class 8 was a four-cylinder 4-6-0 express passenger locomotive designed by George Hughes introduced in 1908.
The Lancashire and Yorkshire Railway (L&YR) Class 7 was a class of Atlantic passenger steam locomotives to the design of John Aspinall. Forty were built between 1899 and 1902. They were known as "High-Flyers" as a result of having a high-pitched boiler that was supposed to increase stability at speed. All passed into London, Midland and Scottish Railway (LMS) ownership on the grouping of 1923, becoming the LMS's only Atlantic tender engine class. The LMS gave them the power classification 2P. Withdrawals started in 1926, and the last was withdrawn in 1934. None were preserved.
The Lancashire and Yorkshire Railway (L&YR) operated two classes of twenty steam railmotors in total.
The Lancashire and Yorkshire Railway Class 32 was a small class of 0-8-2T steam locomotives, intended for heavy shunting and banking duties.
The L&YR Class 30 was a class of 0-8-0 steam locomotives of the Lancashire and Yorkshire Railway. The class was designed by John Aspinall and introduced in 1900.
The L&YR Class 30 was a class of 0-8-0 steam locomotives of the Lancashire and Yorkshire Railway, designed by George Hughes. The prototype was rebuilt from an Aspinall Class 30 locomotive in 1904. Ten new locomotives were built in 1907. The locomotives passed to the London, Midland and Scottish Railway (LMS) in 1923.
The L&YR Class 30 (Hughes) was a class of 0-8-0 steam locomotives of the Lancashire and Yorkshire Railway. The class was designed by George Hughes and introduced in 1910. Twenty-nine were rebuilds from Aspinall's L&YR Class 30 and 40 were new locomotives.
The L&YR Class 26 was a class of 20 2-6-2T passenger steam locomotives of the Lancashire and Yorkshire Railway designed by Henry Hoy and introduced in 1903. Most passed to the London, Midland and Scottish Railway (LMS) at the grouping in 1923 though they were withdrawn soon afterwards with none remaining in service after 1926.
The L&YR Class 2 (Aspinall) was a class of 4-4-0 steam locomotives of the Lancashire and Yorkshire Railway.
The L&YR Class 3 was a class of 4-4-0 steam locomotives of the Lancashire and Yorkshire Railway introduced in 1891 with forty being built. George Hughes rebuilt six locomotives with superheaters between 1908 and 1909, they were later designated L&YR Class 4. All passed to the London, Midland and Scottish Railway at the grouping in 1923 but were withdrawn by 1930.
The L&YR 2-10-0 was a prospective design for a class of 2-10-0 steam locomotives on the Lancashire and Yorkshire Railway. Initial designs were made by George Hughes between 1913 and 1914, but none of the class were built. If they had been, these would have been the UK's first 10-coupled locomotives in regular service.
The Lancashire and Yorkshire Railway (L&YR) Barton Wright 0-6-2T were tank engines introduced by Barton Wright between 1877 and 1883. This was the first use of the 0-6-2T type in Britain.
