The Great Central Railway (GCR) Class 9A was a class of 0-6-2T steam locomotive built between 1889 and 1892. From 1923 the locomotives were redesignated Class N4.
Designed by Thomas Parker for the Manchester, Sheffield and Lincolnshire Railway (MS&LR), a total of 55 locomotives were constructed up to 1892. [2] The MS&LR changed its name to the GCR in 1897. In 1892 the final fourteen locomotives were built with a larger coal bunker, increasing their weight to 61.95 long tons (62.94 t). This last batch was classified as Class 9A Altered, sometimes abbreviated as 9A Alt.
The GCR 9A locos were reclassified as N4 under the LNER locomotive numbering and classification system when the GCR was absorbed into the London and North Eastern Railway after the 1923 grouping. The original design were N4/1 and those with extended bunkers N4/2. [3]
In 1925, shorter chimneys began to be fitted to bring the N4s within the LNER composite loading gauge, creating two further variants N4/2 (short bunker) – the existing N4/2s being recoded as N4/3s – and N4/4 (long bunker). [3]
They were built in three batches and numbered 161, 165, 173 (later renumbered 512–514), 601–638, and 712–725. GCR locos had 5000 added to their original numbers when the line was absorbed by the LNER in 1923, resulting in numbers ranging between 5512 and 5725. As part of the LNER's numbering rationalisation scheme introduced in 1946, the surviving 22 N4s were renumbered between 9225 and 9247 [4] with the earliest built receiving the lowest number, and so on. British Railways, formed on 1 January 1948, added 60000 to all LNER loco numbers.
John George Robinson CBE, was an English railway engineer, and was chief mechanical engineer of the Great Central Railway from 1900 to 1922.
The Great Central Railway Class 9N, classified A5 by the LNER, was a class of 4-6-2 tank locomotives designed by John G. Robinson for suburban passenger services. They were fitted with superheaters, piston valves and Stephenson valve gear.
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 Great Central Railway (GCR) Class 9F was a class of 0-6-2T steam locomotive built between 1891 and 1901. From 1923 the locomotives were redesignated Class N5.
The London and North Eastern Railway (LNER) D40 class is a type of 4-4-0 steam locomotive inherited from the Great North of Scotland Railway (GNSR). It consisted of GNSR class V and GNSR class F. The two classes were similar but the class F was superheated.
The North Eastern Railway (NER) Class H, classified as Class Y7 by the London and North Eastern Railway (LNER) is a class of 0-4-0T steam locomotives designed for shunting.
The NER Class X was a class of 4-8-0T tank locomotive designed by Wilson Worsdell for the North Eastern Railway. They were intended for use as powerful shunting engines to arrange and move coal wagons for loading into ships. In total 15 were built, 10 by the NER between 1909 and 1910, and a further five in 1925 by the London and North Eastern Railway (LNER). They had three cylinders with divided drive: the inside cylinder driving the leading axle, the outside cylinders driving the centre.
The GCR Class 1 was a class of steam locomotives designed by John G. Robinson for the Great Central Railway, and introduced to service between December 1912 and 1913. In the 1923 grouping, they all passed to the London and North Eastern Railway which placed them in class B2. Their classification was changed to B19 in 1945, and all had been retired by the end of 1947.
The Great Central Railway Class 8, known as the London and North Eastern Railway Class B5 following the 1923 Grouping, was a class of fourteen 4-6-0 steam locomotives designed to haul fast goods trains, in particular fish trains.
The Midland Railway Johnson 0-6-0 were a class of locomotives serving Britain's Midland Railway system in the late 19th and early 20th centuries. Between 1875 and 1908 the Midland Railway, under the control of locomotive superintendents Samuel Waite Johnson and Richard Deeley, ordered 935 goods tender engines of 0-6-0 type, both from the railway's own shops at Derby and various external suppliers. Although there were many variations between different batches both as delivered and as successively rebuilt, all 935 can be regarded as a single series, one of the largest classes of engine on Britain's railways. The locomotives served as late as 1964, but none of them now survive.
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.
The GCR Class 1B was a class of 2-6-4T (tank) locomotives on the Great Central Railway. They were notable as the first locomotives of the 2-6-4T wheel arrangement to be used by a British standard-gauge railway; there had been two narrow-gauge examples on the Leek & Manifold Valley Light Railway since 1904.
Robert Absalom Thom was the final Locomotive, Carriage and Wagon Superintendent of the Lancashire, Derbyshire and East Coast Railway, and became a key figure in the locomotive departments of the company's successors, the Great Central Railway and the London & North Eastern Railway. Thom was born at Aberdeen on 14 June 1873. He attended Robert Gordon's College in Aberdeen, where he received a technical education.
The LD&ECR Class D was a class of nine 0-6-4T steam locomotives supplied to the Lancashire, Derbyshire and East Coast Railway in 1904 and 1906 by Kitson & Co. of Leeds. They later became the property of the Great Central Railway and finally the London and North Eastern Railway, upon which they were known as Class M1.
GCR Classes 8D and 8E were two pairs of three-cylinder compound steam locomotives of the 4-4-2 wheel arrangement built in 1905 and 1906 for the Great Central Railway.
The GCR Class 9Q, classified B7 by the LNER, was a class of 4-6-0 mixed traffic locomotives designed by John G. Robinson for fast goods, relief passenger and excursion services on the Great Central Railway. They were a smaller wheeled version of Robinson's earlier Class 9P "Lord Faringdon" express passenger class.
The GCR Class 5 was a class of twelve 0-6-0ST steam tank locomotives designed by Harry Pollitt (engineer) for work in docks operated by the Manchester, Sheffield and Lincolnshire Railway (MS&LR) later renamed Great Central Railway (GCR).
The Great Northern Railway (GNR) Class N1 was an 0-6-2T side tank steam locomotive designed by Henry Ivatt and introduced in 1906. They were all withdrawn from service between 1947 and 1959. None have survived.
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.
The GCR Class 8F was a class of ten 4-6-0 locomotives built for the Great Central Railway in 1906 by Beyer, Peacock and Company to the design of John G. Robinson for working fast goods and fish trains. They passed to the London and North Eastern Railway at the 1923 grouping and received the classification 'B4'.
