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).
Construction and operation
Class 27 locomotives were designed by John Aspinall and 484 were built between 1889 and 1918 at Horwich Works. It was the standard goods engine used by the Lancashire & Yorkshire Railway. Aspinall opted for a two-cylinder format with a non superheated round top boiler. David Joy's configuration of valve gear was employed. By the time Aspinall became general manager of the L&YR on 1 July 1899 more than 400 of the simple but powerful engines had been built. More were built under his successors, Henry Hoy and George Hughes, albeit with some modifications. By 1918 there were the 484 locomotives in the class.
Development and rebuilding
As built, there were three primary boiler versions. The majority (418 locomotives) of those built between 1889 and 1906 had round-top fireboxes when new, and operated on saturated steam. A further twenty of these were built in 1909, and ten more in 1917–18. By this time, some of the earlier locomotives had been rebuilt with Belpaire fireboxes, aome also gaining superheaters. With the introduction of Hughers' classification in 1919, the superheated locomotives were placed in Class 28, those retaining saturated steam becoming Class 27.
Superheating
The L&YR was the first British railway to fit a locomotive with a superheater, this being no. 737 of the 1400 Class 4-4-2 in 1899, and experiments had been conducted with various superheater types since then. Two of the 0-6-0 locomotives built in 1906, nos. 898 and 900, were provided with Schmidt superheaters when new, the purpose being to increase the temperature of steam produced in the boiler so the minimum of energy was lost. After months of trials, 20 further superheated engines were authorised to be built and the first of the superheated class 27s emerged from Horwich Works in 1909. The superheated 27s had the same boiler pressure as the originals, 180 psi. This first batch of twenty had round topped boilers like nos. 898 and 900. In 1914, no. 625 was rebuilt with a superheated Belpaire boiler, but no others were so treated – between 1926 and 1931, most of the others were rebuilt with saturated round-top boilers, only four, nos. 830, 901/3/4 (by this time renumbered as LMS 12533–6) retaining their superheated round-top boilers until withdrawal in 1934–36.
Belpaire fireboxes
The L&YR had begun using the Belpaire firebox in 1897, with the 1351 Class 0-6-0T. From 1911, some of the 0-6-0s were rebuilt with these fireboxes, at first continuing to use saturated steam, but from 1913 some of the Belpaire rebuilds were also provided with superheaters. In 1912 a batch of 20 was constructed with both Belpaire fireboxes and superheaters.
Ownership changes
It is a tribute to the soundness, usefulness and simple practicality of Aspinall's design that 300 of the class passed into the ownership of the London, Midland and Scottish Railway (LMS) and around 50 were operating in British Railways (BR) service in summer 1960. British Railways took ownership of 235 of the class in 1948 and renumbered them 52088-52529 (with gaps) by the addition of 40000 to their LMS numbers.
32 locomotives were loaned to the Railway Operation Division during World War I, all of them were eventually returned once the war had ended.
Preservation
One locomotive, 1895-built L&YR number 1300 (later LMS 12322 and BR 52322) has survived and is preserved at the East Lancashire Railway. It is owned by Andy Booth and its most recent overhaul was completed in 2021.
The rebuild
The rebuild of the Class 27 was the L&YR Class 28, designed by George Hughes.
