1896-built L&YR number 1300 (later LMS 12322 and BR 52322) arrived at Ribble Steam Railway in mid-December 2009 (currently on loan at ELR)

 The Lancashire and Yorkshire Railway (L&YR) Class 27 is a class of 0-6-0 steam locomotive designed for freight work.

They were designed by John Aspinall and 484 were built between 1889 – 1918 at Horwich works. The Class 27 was the standard goods engine of the Lancashire & Yorkshire Railway. Aspinall opted for the two cylinder format with a non superheated round top boiler. David Joy’s configuration of valve gear was employed. By the time of Aspinall’s departure from the L&YR in 1899 over 400 of these simple but powerful engines had been built. More were built under his successor Henry Hoy and George Hughes, albeit with some modifications. By 1918 the class totalled 484.

It was under Hughes that the class became the subject of early experiments in superheating. This was the process of increasing the temperature of the steam produced in the boiler so the minimum of energy was lost. After many months of trails a further 20 superheated engines were authorised to be built and the first of these superheated class 27’s emerged from Horwich Works in 1909. The superheated 27’s retained the boiler pressure of the originals (180 psi). This first batch had round topped boilers but in 1912 a second batch of 20 was constructed with Belpaire fireboxes.

Although the class was augmented by a further 60 engines between 1900 and 1909 with another ten added in 1917-18. The final five built reverted entirely to the original 1889  specification. It is a tribute to the soundness usefulness and simple practicality of Aspinall’s design that some 300 of the class passed into the hands of the LMS and around 50 were still in British Railways service as late as the summer of 1960.

This locomotive is currently off-site.
