Of the approximately 20,000 locomotives in service on the railways in Britain in 1900 nearly 10% (around 1900) were six-coupled tender engines. These 0-6-0 engines were primary designed to haul goods traffic. Many of these were noteworthy and long lived classes and the Aspinall class 27 is one of these.

The Lancashire & Yorkshire Railwaty (L&YR) carried a very large volume of freight traffic which was mainly entrusted to Barton Wright class 25 engines introduced in 1876.

Aspinall opted for the two cylinder format with a non-superheated round top boiler. 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 successors Hoy and Hughes, albeit with some modifications. By 1918 the class totalled 484.

They were built over a long period until 1918, when 468 engines had been built at Horwich by Aspinall and his successors Hoy and Hughes.

The first engine was withdrawn in 1931 and 245 came into BR stock.

In such a large class there was inevitably a large number of variations, particularly in the boilers. These are set out below.

  • The locomotives built in 1889 had round topped saturated boilers.
  • 52461-7 were constructed in 1917-18 and were reputedly made from spare parts left over after the rest of the class had been constructed.
  • 52515 was rebuilt from an Aspinall engine and 52517-29 were built new as superheated engines with round topped fireboxes and extended smokeboxes in 1909 by Hughes. The survivors were later rebuilt with saturated boilers and short smokeboxes.
  • Many engines were rebuilt with Belpaire boilers and extended smokeboxes from 1911 onwards.

In 1905 Hughes fitted a Schmidt superheating device to two locomotives as a trial. These two were also fitted with piston valves instead of slide valves although the joy valve gear was retained. The superheated locomotives operated alongside non-superheated engines which demonstrated that the superheated engines performed better in that they could haul heavier loads (about 10% greater) but also consumed less coal (about 12½% less). After a lengthy trial period approval was given to fit superheating to another 20 locomotives which was completed at Horwich works in 1909.

In 1912 Hughes introduced a superheated version of the class with Belpaire boilers and extended smokeboxes which became the class 28. 63 locomotives were converted from the class 27 (52088) engines to the 28 class (52528) between 1913 and 1922.

Thirty-two locomotives served with the ROD in WW1.
