The LNER Class Y1 was a class of 0-4-0 geared steam locomotives built by Sentinel Waggon Works for the London and North Eastern Railway and introduced in 1925. They passed into British Railways ownership in 1948 and were numbered 68130-68153 [1] but 68134 was withdrawn almost immediately and may not have carried its BR number.
The superheated vertical water-tube boiler and the engine were similar to those used in Sentinel steam wagons. There were variations within the class as regards boiler size and fuel capacity and these were denoted by sub-classes Y1/1 to Y1/4.
The engines had poppet valves and reversing was by sliding camshaft. The advantage of the water-tube boiler was that steam could be raised much more quickly than with a conventional fire-tube boiler.
Final drive to the wheels was by sprocket chain. Some engines had a gear ratio of 11:25 and some 9:25. Tractive effort was:
There is disagreement between sources. According to LNER Encyclopedia [6] there were six Y1/1s and sixteen Y1/2s.
A geared steam locomotive is a type of steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design.
The Caledonian Railway 60 Class were 4-6-0 passenger engines designed by William Pickersgill and introduced in 1916. Six were built by the Caledonian Railway at its own St. Rollox works in 1916–17, and all of them passed into LMS ownership in 1923. A further twenty locomotives of a slightly modified design were built by the LMS under the auspices of George Hughes in the period of 1925–1926.
Sentinel Waggon Works Ltd was a British company based in Shrewsbury, Shropshire that made steam-powered lorries, railway locomotives, and later, diesel engined lorries, buses and locomotives.
The Great Central Railway (GCR) Class 8K 2-8-0 is a class of steam locomotive designed for heavy freight. Introduced in 1911, and designed by John G. Robinson, 126 were built for the GCR prior to the First World War. Including wartime construction for the British Army ROD and the post-war GCR Class 8M, the class and its derivatives totalled 666 locomotives.
The Great Eastern Railway (GER) Class Y14 is a class of 0-6-0 steam locomotive. The LNER classified them J15.
The NBR C Class is a class of 0-6-0 steam locomotives designed by Matthew Holmes for freight work on the North British Railway (NBR). They were introduced in 1888 with inside cylinders and Stephenson valve gear. A total of 168 locomotives was built, of which 123 came into British Railways ownership at nationalisation in 1948. This was the last class of steam engine in service in Scotland.
The London and North Eastern Railway Class J38 was a class of steam locomotive designed for freight transport. They were designed by Nigel Gresley and introduced in 1926. A total of 35 were built at the LNER's Darlington Works in 1926 and they were used in Scotland. All passed into British Railways ownership in 1948 and they were renumbered from 5900–5934 to 65900–65934.
The Caledonian Railway 72 Class was a class of 4-4-0 steam locomotives introduced by William Pickersgill for the Caledonian Railway (CR) in 1920. Thirty-two locomotives were built and all survived to be taken over by the London, Midland and Scottish Railway (LMS) in 1923 and by British Railways (BR) in 1948. The earlier 113 Class, of which 16 were produced, were similar but slightly smaller. These were the Caledonian's last express passenger locomotives, and technically, the last of the Dunalastair series, and were unofficially dubbed, Dunalastair V.
The London and North Eastern Railway (LNER) Class B17, also known as "Sandringham" or "Footballer" class was a class of 4-6-0 steam locomotive designed by Nigel Gresley for hauling passenger services on the Great Eastern Main Line. In total 73 were built.
The London and North Eastern Railway (LNER) Class A8 was a type of 4-6-2T steam locomotive, designed by both Vincent Raven and Nigel Gresley. They were rebuilt from the LNER Class H1s, a 4-4-4T class.
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 LNER Class Y3 was a class of 0-4-0 geared steam locomotives built by Sentinel Waggon Works for the London and North Eastern Railway and introduced in 1927. They passed into British Railways ownership in 1948 and were numbered 68154-68185. At least one was based at Immingham in 1950.
The LNER Class Y10 was a class of two 0-4-0T geared steam locomotives built by Sentinel Waggon Works for the London and North Eastern Railway and introduced in 1930. The LNER numbered them 8403 and 8404 but they were later re-numbered 8186 and 8187. This was the second use of the classification Y10 by the LNER. The first was for an ex-North British Railway 0-4-0 steam tender locomotive, withdrawn 1925.
The North Eastern Railway (NER) Class K classified as Class Y8 by the London and North Eastern Railway (LNER) is a class of 0-4-0T steam locomotives designed for shunting. It was designed by Thomas W. Worsdell and five of these tiny engines were built in 1890. These were numbered 559-63.
The Sentinel boiler was a design of vertical boiler, fitted to the numerous steam wagons built by the Sentinel Waggon Works.
The H&BR Class G3 was a class of 0-6-0T steam locomotives of the Hull and Barnsley Railway (H&BR). The H&BR became part of the North Eastern Railway (NER) in 1922 and the NER became part of the London and North Eastern Railway (LNER) in 1923.
The GER Class M15 was a class of 160 2-4-2T steam locomotives designed by Thomas William Worsdell and built for the Great Eastern Railway between 1884 and 1909. The original (F4) class of locomotives were fitted with Joy valve gear which was notoriously difficult to 'set'. This earned them the nickname of 'Gobblers' thanks to their high coal consumption rates. As a result, between 1911 and 1920, 32 of them were rebuilt by James Holden with Stephenson valve gear and higher pressure boilers. Despite this, the nickname stuck for many years after.
The GCR Classes 9D, 9H and 9M were a class of 124 0-6-0 Steam locomotives designed by Harry Pollitt for freight work on the Manchester, Sheffield and Lincolnshire Railway (MS&LR) later renamed Great Central Railway (GCR).
A steam motor is a form of steam engine used for light locomotives and light self-propelled motor cars used on railways. The origins of steam motor cars for railways go back to at least the 1850s, if not earlier, as experimental economizations for railways or railroads with marginal budgets. These first examples, at least in North America, appear to have been fitted with light reciprocating engines, and either direct or geared drives, or geared-endless chain drives. Most incorporated a passenger carrying coach attached to the engine and its boiler. Boiler types varied in these earlier examples, with vertical boilers dominant in the first decade and then with very small diameter horizontal boilers. Other examples of steam motor cars incorporated an express-baggage or luggage type car body, with coupling apparatus provided to allow the steam motor car to draw a light passenger coach.
The NER Class Z was an Atlantic class of locomotives designed by Vincent Raven. It was introduced in 1911.
