The NER Class F (LNER Class D22) was a class of 4-4-0 steam locomotives of the North Eastern Railway. It was designed by Thomas William Worsdell and introduced in 1887.
Class F (compound expansion) and Class F1 (simple expansion) 4-4-0s were developments of T.W. Worsdell's experimental Class D 2-4-0. The Class Ds were two-cylinder compounds of the von Borries type. However, the 2-4-0 wheel arrangement was found unsuitable and this led to the development of the Class F 4–4–0. [1]
| Class | Build date | No. built |
|---|---|---|
| D | 1886, 1888 | 2 |
| F | 1887 | 10 |
| F1 | 1887 | 10 |
| F | 1890–1891 | 15 |
| Total | 37 |
Between 1896 and 1911 all the Class D, F and F1 locomotives were rebuilt into one 4-4-0 class with 18in x 24in simple expansion cylinders, piston valves, and Stephenson valve gear. They had been built with slide valves and Joy valve gear. The combined class was designated "Class F" from 1914. Superheaters were fitted between 1913 and 1920.
The information box (above right) shows the dimensions after 1911. Before this, dimensions varied:
They were initially used for express passenger services. Between 1892 and 1894 they were displaced by newer locomotives and relegated to secondary duties. By the time of the 1923 Grouping, they had been further relegated and were typically used for branch line stopping trains.
They were withdrawn between 1927 and 1935 and none were preserved.
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 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 Great Northern Railway (GNR) Class C1 is a type of 4-4-2 steam locomotive. One, ex GNR 251, survives in preservation. Much like their small boiler cousins, they were capable of reaching speeds of up to 90 mph (145 km/h). They were also known as Large Atlantics.
Thomas William Worsdell was an English locomotive engineer. He was born in Liverpool into a Quaker family.
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 North Eastern Railway Class E1, classified as Class J72 by the London and North Eastern Railway (LNER), is a class of small 0-6-0T steam locomotives designed by Wilson Worsdell for shunting. They had inside cylinders and Stephenson valve gear.
The North Eastern Railway (NER) Class E, classified as Class J71 by the London and North Eastern Railway (LNER), was a class of small 0-6-0T steam locomotive designed by T.W. Worsdell. They had inside cylinders and Stephenson valve gear and were the basis for the later NER Class E1.
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 NER Class 3CC was a 4-4-0 steam locomotive designed by Wilson Worsdell for the North Eastern Railway and built in 1893. Only one was built and it was a compound expansion version of the simple expansion NER Class M1. The 3CC was originally classified M but was re-classified 3CC in 1914, at the same time as the M1 was re-classified M.
A compound locomotive is a steam locomotive which is powered by a compound engine, a type of steam engine where steam is expanded in two or more stages. The locomotive was only one application of compounding. Two and three stages were used in ships, for example.
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 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.
The NER Class L was a class of 0-6-0T steam locomotives of the North Eastern Railway. They were a specialised design, intended for use on the Redheugh and Quayside banks on either side of the River Tyne. They were replaced on the Quayside branch by NER Class ES1 electric locomotives in 1905 but were re-allocated to other duties.
A divided drive locomotive is a steam locomotive that divides the driving force on its wheels by using different cylinders to power different pairs of driving wheels in order to give better weight distribution and reduce "hammer blow" which can be damaging to the track, or else to enable the wider spacing of the driving wheels to accommodate a larger firebox.
The NER Class C was a class of 171 two-cylinder steam locomotives of the 0-6-0 wheel arrangement built between 1886 and 1894 for the North Eastern Railway. These engines were designed to fill NER's need for goods engines; however, issues with reliability and fuel consumption led to all 171 being rebuilt to the simpler Class C1 type between 1901 and 1913.
The NER Class A was a class of 2-4-2 tank locomotives designed by Thomas William Worsdell and built at Gateshead works for the North Eastern Railway (NER). Sixty locomotives were built between 1886 and 1892. At this time the class was designated class A by the NER and was the first class in the company to be given an alphabetical letter classification.
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.
The North Eastern Railway was formed by merger in 1854 and merged into the London and North Eastern Railway at the grouping in 1923. Between those dates five men held the post of Locomotive Superintendent.
The NER Class G was a class of 4-4-0 steam locomotives of the North Eastern Railway. It was designed by Thomas William Worsdell and introduced in 1887.
The NER Class Z was an Atlantic class of locomotives designed by Vincent Raven. It was introduced in 1911.
