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 NER 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 (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 NER Class R was a class of 4-4-0 steam locomotive, designed by Wilson Worsdell for the North Eastern Railway. They passed to the London and North Eastern Railway (LNER) in 1923. In 1936, some were rebuilt with long-travel piston valves and classified D20/2. The unrebuilt locomotives were re-classified D20/1.
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 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 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 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 Class S.
The NER Class W1 was a 4-6-2T steam locomotive of the North Eastern Railway. The class was introduced in 1914 as a rebuild of Wilson Worsdell's NER Class W 4-6-0T. At the 1923 Grouping, they all passed to the London and North Eastern Railway, who placed them in their Class A6.
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 P1 was a class of 0-6-0 steam locomotives of the North Eastern Railway. Class P1 was a development of Class P, having a boiler four inches longer, and a firebox six inches longer. To accommodate these, the wheelbase was increased by nine inches. The cylinder stroke was also increased by two inches.
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 saturated 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 history mechanical history.
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 F 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 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 N was a class of 0-6-2 tank locomotives of the North Eastern Railway. It was designed by Wilson Worsdell and introduced in 1893.
The NER Class U was a class of 0-6-2 tank locomotives of the North Eastern Railway. It was designed by Wilson Worsdell and introduced in 1902.
The NER Class V was a class of twenty steam locomotives of the 4-4-2 wheel arrangement. They were designed by Wilson Worsdell for the North Eastern Railway (NER) as express passenger locomotives.
