Aspinall 0-6-0. If it ain't nostalgia I don't know what is

Backs off at Embsay for disposal


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.
