4-4-0 is a locomotive type with a classification that uses the Whyte notation for the classification of steam locomotives by wheel arrangement and represents the arrangement: four leading wheels on two axles, four powered and coupled driving wheels on two axles, and a lack of trailing wheels. Due to the large number of the type that were produced and used in the United States, the 4-4-0 is most commonly known as the American type, but the type subsequently also became popular in the United Kingdom, where large numbers were produced.
Under the Whyte notation for the classification of steam locomotives, 2-6-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, six powered and coupled driving wheels on three axles and no trailing wheels. This arrangement is commonly called a Mogul.
The London and North Eastern Railway (LNER) produced several classes of locomotive, mostly to the designs of Nigel Gresley, characterised by a three-cylinder layout with a parallel boiler and round-topped firebox. It produced the most famous locomotive of its day, 4468 'Mallard', the holder of the world steam locomotive speed record. It also built the world-famous 4472 'Flying Scotsman'. However, its locomotive inheritance was much greater than just the 'A4 Class', it also produced highly successful mixed-traffic and freight designs.
Under the Whyte notation for the classification of steam locomotives, 4-8-0 represents the wheel arrangement of four leading wheels on two axles, usually in a leading truck or bogie, eight powered and coupled driving wheels on four axles and no trailing wheels. In North America and in some other countries the type was usually known as the Twelve-wheeler.
The Hunslet Austerity 0-6-0ST is a class of steam locomotive designed by Hunslet Engine Company for shunting. The class became the standard British shunting locomotive during the Second World War, and production continued until 1964 at various locomotive manufacturers.
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 NBR K Class is a class of 4-4-0 steam locomotive of the North British Railway. The first batch was designed by Matthew Holmes in 1902 and had 6-foot-6-inch (1.981 m) driving wheels for express passenger work. Three more batches were designed by William P. Reid with 6-foot-0-inch (1.829 m) driving wheels for mixed traffic work. This included perishable goods, such as fish from Mallaig and Aberdeen. They had inside cylinders and Stephenson valve gear. The D34 locomotives, commonly known as Glen Class, were built with superheaters. The LNER later fitted superheaters to all D26, D32, and D33 engines as well. All engines of the K class are sometimes known as Glen Class, although the designation is strictly reserved to the fourth (D34) batch.
Dugald Drummond was a Scottish steam locomotive engineer. He had a career with the North British Railway, LB&SCR, Caledonian Railway and London and South Western Railway. He was the older brother of the engineer Peter Drummond, who often followed Dugald's ideas in his own work.
Under the Whyte notation for the classification of steam locomotives, 0-8-4 represents the wheel arrangement of no leading wheels, eight powered and coupled driving wheels on four axles, and four trailing wheels on two axles.
Neilson and Company was a locomotive manufacturer in Glasgow, Scotland.
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 Caledonian Railway 264 and 611 classes were 0-4-0 saddle tank locomotives designed by Dugald Drummond and built by Neilson and Company in 1885. Later examples were built at St Rollox Works under the direction of John F. McIntosh in 1895, 1900, 1902 and 1908.
The GER Class 209 was a class of 0-4-0 saddle tank steam locomotives of the Great Eastern Railway. These locomotives were similar to the NBR G Class but had flat-topped, instead of round-topped, tanks. A total of eight were built – four by Neilson and Company in 1874 and four more by the GER's Stratford Works between 1897 and 1903.
'Pug' locomotives are small steam locomotives which were produced for light shunting work, usually at dockyards, factory sites, steelworks, collieries, and other similar locations. The name is derived from a common term in Scotland for a small industrial shunting engine, typically an 0-4-0 tank.
The NBR D Class was a class of 0-6-0 tank locomotives designed by Matthew Holmes for short distance freight, station pilot, and heavy shunting duties on the North British Railway.
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 NBR Class N was a class of 4-4-0 steam locomotive of the North British Railway. The class was designed by Matthew Holmes and later rebuilt by Holmes's successor, Reid. A total of 12 were produced.
The NBR Class D was a class of 0-6-0 steam locomotive of the North British Railway, often known as the Wee Drummonds. The class was designed by Dugald Drummond. A total of 101 were produced.
The NBR F Class was a class of 0-6-0 tank locomotives, designed by William P. Reid on the North British Railway. They were used for dockyard shunting duties.
