The North Eastern Railway Class S2 - London and North Eastern Railway Class B15 - was a mixed-traffic 4-6-0 steam locomotive designed by Vincent Raven. The design was based on NER Class S.
The first seven were built with saturated (non-superheated) boilers, however the remaining thirteen were fitted with Robinson 24-element superheaters. The saturated B15s were eventually fitted with superheaters. Some of these rebuilds used Schmidt superheaters, however they were eventually converted to use Robinson superheaters, as Robinson superheaters were the LNER’s standard type of superheaters.
The last of the class, No.825 was fitted with Stumpf Uniflow cylinders. The inlet and exhaust ports were separate. Although the exhaust port was always the same size, the inlet port could vary in size according to the position of the cutoff. In 1918, the system was used on C7 No.2212, with a tidier result. Due to the special attention required for these experimental locomotives, in March 1924, the locomotive was rebuilt as a standard B15, matching the other members.
Although they were used on their suitable work, they steamed poorly if handled with crew who wasn’t used to the B15s (which also affected the B13s), and thus they were unpopular with crew who didn’t have enough experience on the B15s.
Withdrawal commenced with No.788 in September 1937, and all were gone by December 1947, with the last being No.1696 (NER No.820). None were preserved. [2]
Sir Vincent Litchfield Raven, KBE was an English railway engineer, and was chief mechanical engineer of the North Eastern Railway from 1910 to 1922.
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, in some steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet.
The London and North Eastern Railway 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 North Eastern Railway (NER) Class P3, classified J27 by the LNER, is a class of 0-6-0 steam locomotive. The P3 Class was designed by Wilson Worsdell and was a relatively minor modification of the existing North Eastern Railway Class P2. The most significant change was a deeper firebox with shallower sloping fire grate. This was achieved by raising the boiler slightly, and by reducing the clearance between the firebox and the rear axle. The P3 Class were a freight engine by nature and used for hauling long trains of freight.
The North Eastern Railway Class T3, classified as Class Q7 by the LNER, is a class of 0-8-0 steam locomotive designed for heavy freight. Five were built by the NER in 1919 and a further 10 by the London and North Eastern Railway (LNER) in 1924.
The North Eastern Railway (NER) Class C1, was a class of 0-6-0 freight locomotives designed by T.W. Worsdell. They were used throughout the NER system, although particularly in Teesside between 1886 and 1962.
The North Eastern Railway Class T2, classified as Class Q6 by the LNER, is a class of 0-8-0 steam locomotive designed for heavy freight, especially for hauling long coal trains to various collieries in the North Eastern region of the UK, with a maximum speed of 40 miles per hour. 120 were built at Darlington Works and Armstrong Whitworth between 1913 and 1921 to the design of Vincent Raven, based on the NER Class T and T1. The batch of fifty built by Armstrong Whitworth from 1919 were A-W's first locomotives to be built, after the conversion of their Scotswood works from ordnance to peacetime production.
The North Eastern Railway Class S3, classified B16 by the LNER, was a class of 4-6-0 steam locomotive designed for mixed traffic work. It was designed by Vincent Raven and introduced in 1920. The earlier members of this class were fitted with Westinghouse Brakes - all of this equipment was removed during the 1930s.
The North Eastern Railway (NER) Class Y 4-6-2T tank locomotives were designed whilst Wilson Worsdell was Chief Mechanical Engineer, but none were built until 1910 by which time Vincent Raven had taken over.
The North Eastern Railway Class S was a 4-6-0 type of steam locomotive designed for express passenger workings. The first example was built in 1899. They were very similar to the NER Class S1, except for the smaller wheels of the former.
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 NER Class P was a class of 0-6-0 steam locomotives of the North Eastern Railway. They were designed by Wilson Worsdell for mineral traffic.
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 South African Railways Class 16C 4-6-2 of 1919 was a steam locomotive.
The NER B and B1 Classes were two classes of 0-6-2 tank locomotives designed by Thomas William Worsdell for heavy freight and mineral on the North Eastern Railway, introduced in 1886. They were tank engine versions of the NER C1 Class 0-6-0, using both simple expansion and also the von Borries configuration for two-cylinder compound locomotives. Both types were later rebuilt using superheated steam and the compounds were also rebuilt as simple expansion locomotives, and eventually formed a single class. Many of the superheated locomotives were also later returned to saturated steam as their original boilers wore out. As a result the classes have had a very complex mechanical history.
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.
The NER Class S1 was a class of 4-6-0 steam locomotives of the North Eastern Railway. It was designed by Wilson Worsdell and five locomotives were built between 1900 and 1901 at Gateshead works. The S1 was similar to the NER Class S but had larger driving wheels and a higher boiler pressure.
The NER Class R1 was a class of 4-4-0 steam locomotives of the North Eastern Railway. The class was designed by Wilson Worsdell and built from 1908 to 1909.
The North British Atlantic, later known as NBR Class H, and then as LNER Class C11 was a class of 4-4-2 steam locomotive of the North British Railway. The class was designed by William P. Reid, Locomotive Superintendent of the NBR, and entered service under his direction. They were the heaviest, longest, and most powerful locomotives ever employed on the North British Railway.
The NER Class Z was an Atlantic class of locomotives designed by Vincent Raven. It was introduced in 1911.
