The L&YR Class 26 was a class of 20 2-6-2 T 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 Most passed to the London, Midland and Scottish Railway (LMS) at the grouping in 1923 though they were withdrawn soon afterwards with none remaining in service after 1926. [1]

Design and construction

Hoy intended the class to work Manchester, Rochdale, Oldham and Bury services where heavier trains and on lines gradients were giving difficulties to the Aspinall 2-4-2T radial tank locomotives. To a degree they were an evolutionary design based on the enlarged version of the 2-4-2T radial tanks with six-coupled wheels and the belpaire firebox used on the Aspinall Atlantic High Flyers and Coal engine 0-8-0 types. [2]

Service

On their introduction in 1903 they were allocated to Liverpool to Southport workings covering a temporary shortage of electric stock; they were subsequently placed on their intended routes where they had an initially successful introduction, [2] but problems with the class shortly emerged. Their heavy weight was not good for the track and the long rigid wheelbase put pressure on rails with severe curves in sidings. The flanges were removed from the centre driving wheels which eased some issues but increased the risk of derailment on track which was slightly out of alignment and most notably at junctions. This is due to flangeless driving wheels working better on smaller wheels placed closer together. The side tanks tended to badly leak and they gained a reputation for poor stopping ability. [3]

Where George Hughes produced a superheated upgrade to the L&YR Class 5 2-4-2Ts, they were able to perform the services allocated to the 2-6-2Ts and the latter were removed from passenger services in 1913. They were then placed on banking and shunting duties with water pickup equipment and coal rail removed for increased visibility for these duties. However they were not well-suited to these duties due to large 5 ft 8 in (1.73 m) driving wheels and flangeless centre-wheels. [3]

Withdrawal

One was withdrawn with unrepairable cracked frames in 1920. A total of thee, Nos 202, 404 and 125 were withdrawn before being allocated a LMS number in 1923. In the event only two (11704 and 11711) actually carried their allocated LMS number and all members of the class were withdrawn by 1926. [5] All had been scrapped by 1928 and none have been preserved.

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 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.
