The GCR Class 8B was a class of 27 two-cylinder steam locomotives of the 4-4-2 wheel arrangement built between 1903 and 1906 for the Great Central Railway. They were nicknamed "Jersey Lillies" after the famous music star Lillie Langtry. [1]
Facing a potential rise in passenger traffic, the Great Central Railway placed an order for two pairs of different locomotives from the North British Locomotive Company of Glasgow in 1903 - one pair being the 4-6-0 GCR Class 8C, the other pair being this 4-4-2 locomotive. The two locomotives shared as many common components as possible to allow easy conversion of the 8Bs to the 4-6-0 configuration - and both designs borrowed heavily from John G. Robinson's earlier GCR Class 8.
However, due to a much smaller than anticipated traffic increase, no further Class 8Cs were built, and instead a further 25 Class 8Bs were ordered and built between 1904 and 1906 - built with larger fireboxes as there was no longer a need to convert the locomotives to a 4-6-0 configuration. In 1909 and 1910, the original locomotives also received this larger firebox.
Despite Robinson commencing the conversion to superheaters in 1912, the conversion was not actually completed until 1936. At the same time, any locomotive requiring cylinder replacement saw both larger cylinders and piston valves being fitted - 20 of the class would eventually receive this modification. From 1921, the Ramsbottom safety valves were phased out and removed, to be replaced by Ross pop safety valves. Another modification was the fitting of ash ejectors. However, these were removed in the 1930s.
Following a high-speed incident that caused severe damage to its frame and cylinders, No. 1090 was rebuilt with 3 simple expansion cylinders in 1908, as a comparison to the GCR Classes 8D and 8E. These cylinders had their Stephenson valve gear replaced with Walschaerts valve gear, which was the only application of this valve gear, excluding railcars, on a GCR locomotive. Instead of all three cylinders being fitted with Walschaerts on one axle, the two outside cylinders drove the second axle, and the inside cylinder drove the first axle. The experiment was reverted in 1922 when No. 1090 was rebuilt, with the original 2 cylinders and Stephenson valve gear being refitted.
Following the merger of the GCR into the London & North Eastern Railway, the class became known as the LNER Class C4. In 1925, several C4s were fitted with the LNER's trademark "Flowerpot" chimney, with one locomotive, No. 6085, also modified to fit the LNER composite gauge - a modification that the remainder of the class underwent between 1936 and 1939. In 1929, a further LNER classification change was made - the non-superheated locomotives were designated Class C4/1, those fitted with superheaters but still utilized slide valves Class C4/2, and those with both superheaters and piston valves became Class C4/3. By 1932, the re-gauged No. 6085 had been given the designation Class C4/4 - which became more populated as Class C4/3s were cut down. By 1939, all Class C4/1s and Class C4/3s had been redesignated as either Class C4/2s or Class C4/4s - by this time all locomotives were both superheated and had also been cut down to the LNER composite gauge.
During the 1930s, the C4s were struggling with an increase in passenger traffic. Replaced by the LNER B17/4s, some of the class moved away from the Great Central Main Line to the Great Eastern Main Line and to former GNR lines, where they hauled stopping passenger trains and secondary duties.
Following an accident at Banbury in 1939, the first locomotive, No. 6090 (the same engine as No. 1090, which had already been modified after a previous accident), was withdrawn from service. Two more members were withdrawn during World War II, these being Nos. 5266 and 6087 in October 1943 and November 1944 respectively. The rest of the class began being withdrawn from 1947, although 20 locomotives made it into British Railways hands following the nationalisation of the British railways. However, none received their BR numbers. The last locomotive, No. 2918, was withdrawn from Lincoln (Shed 40A) on 2 December 1950, and none survived into preservation.
Under the Whyte notation for the classification of steam locomotives, 4-6-2 represents the wheel arrangement of four leading wheels on two axles, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The 4-6-2 locomotive became almost globally known as a Pacific type after a New Zealand locomotive that was shipped across the Pacific Ocean.
The Caprotti valve gear is a type of steam engine valve gear invented in the early 1920s by Italian architect and engineer Arturo Caprotti. It uses camshafts and poppet valves rather than the piston valves used in other valve gear. While basing his design on automotive valves, Caprotti made several significant departures from this design to adapt the valves for steam. Having agreed a joint-venture with Worcester-based engineering company Heenan & Froude from 1938, Heenan & Froude fully acquired Caprotti post-World War II in 1947.
The London and North Eastern Railway LNER Gresley Classes A1 and A3 locomotives represented two distinct stages in the history of the British 4-6-2 "Pacific" steam locomotives designed by Nigel Gresley. They were designed for main line passenger services and later express passenger services, initially on the Great Northern Railway (GNR), a constituent company of the London and North Eastern Railway after the amalgamation of 1923, for which they became a standard design. The change in class designation to A3 reflected the fitting to the same chassis of a higher pressure boiler with a greater superheating surface and a small reduction in cylinder diameter, leading to an increase in locomotive weight. Eventually all of the A1 locomotives were rebuilt, most to A3 specifications, but no. 4470 was completely rebuilt as Class A1/1.
The GER Class L77, LNER Class N7, is a class of 0-6-2T steam locomotives. They were designed by Alfred John Hill of the Great Eastern Railway and introduced in 1915. The design was perpetuated by Nigel Gresley of the LNER after the 1923 grouping. 134 were built and one example is preserved.
The LNER W1 No. 10000 was an experimental steam locomotive fitted with a high pressure water-tube boiler. Nigel Gresley was impressed by the results of using high-pressure steam in marine applications and so in 1924 he approached Harold Yarrow of shipyard and boilermakers Yarrow & Company of Glasgow to design a suitable boiler for a railway locomotive, based on Yarrow's design.
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, 2-6-2+2-6-2 is an articulated locomotive using a pair of 2-6-2 power units back to back, with the boiler and cab suspended between them. The 2-6-2 wheel arrangement has a single pair of leading wheels in a leading truck, followed by three coupled pairs of driving wheels and a pair of trailing wheels in a trailing truck.
The Great Central Railway (GCR) Class 8A was a class of 0-8-0 steam locomotive built between 1902 and 1911 for handling heavy coal trains over the Pennines. They all passed to the LNER in 1923, who redesignated them Class Q4. They were withdrawn from service between 1934 and 1951.
Although overshadowed by the later and more famous steam locomotives that John G. Robinson would go on to design, the Great Central Railway Class 11B 4-4-0 Express Passenger engines were a successful class which totalled 40. Built from 1901 to 1903, in later rebuilt form as 11D, some 11Bs would last in service until 1950. Railwaymen continued to refer to the class as "11B" even after all were rebuilt to 11D. Being contemporary with and to some extent the 4-4-0 version of Robinson's much more numerous 0-6-0 goods class 9J, which were known as "Pom-Poms", the 11Bs acquired the nickname "Pom-Pom Bogies". The London & North Eastern Railway classified the 11Bs, along with their 11C and 11D rebuilds, as Class D9.

The GCR Class 8C was a class of a pair of 4-6-0 locomotives built for the Great Central Railway in 1903–1904 by Beyer, Peacock and Company. They passed to the London and North Eastern Railway at the 1923 grouping and received the classification B1 They were reclassified B18 in 1943 and both were retired in 1947.
GCR Class 8G was a class of 10 two-cylinder steam locomotives of the 4-6-0 wheel arrangement built in 1906 for the Great Central Railway.

A total of six were built: one in 1917, and five in 1920. They were sometimes known as the Lord Faringdon class, from the name of the first one built.

The Indian Railways SP class is a class of Indian steam locomotives used for passenger trains which was built around 1905. In the designation SP stands for Standard Passenger. The design originated from a BESA standard.
The NER Class Z was an Atlantic class of locomotives designed by Vincent Raven. It was introduced in 1911.
