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 increased weight of trains in the early 1900s and need for improved power onexpresses and boat trains indicated a need for more powerful engines. Hughes created a design with a boiler producing saturated steam, slide valves and Joy valve gear. Around the time of their construction, they were nicknamed "Dreadnoughts" on account of their large size. The locomotives proved "sluggish, poor runners and poor steamers". They were subject to a number of modifications to improve steamingand in 1919–20, fifteen were rebuilt with superheaters, piston valves, Walschaerts valve gear and slightly larger cylinders. The nominal tractive effort of the rebuilds made them, for a time, the second most powerful in Great Britain. Improved performance of the rebuilt locomotives and favourable test comparisons with LNWR locomotives triggered the L&YR to order more of the type between 1921 and 1925.
