A number of different numbering and classification schemes were used for the locomotives owned by the London, Midland and Scottish Railway (LMS) and its constituent companies; this page explains the principal systems that were used.
The London and North Western Railway (LNWR) Webb Coal Tank is a class of 0-6-2T steam locomotive. They were called "Coal Tanks" because they were a side tank version of Webb's standard LNWR 17in Coal Engine, an 0-6-0 tender engine for slow freight trains.
The Midland Railway 1377 Class was a class of 185 0-6-0T tank locomotives. They were introduced in 1878 by Samuel W. Johnson, and were almost identical to the 1102 class of 1874; the latter having fully enclosed cabs, while the 1377 class were built without a rear to the cab and only a short cab roof, hence their nickname "half-cabs". They were given the power classification 1F.
The Lancashire and Yorkshire Railway Class 5 were 2-4-2T steam locomotives designed by Chief Mechanical Engineer (CME) John Aspinall and introduced from 1889 for local passenger work. Later batches included progressive modifications such as extended coal bunkers and Belpaire fireboxes. The final batch built from 1911 to 1914 under George Hughes incorporating superheated boilers gave increased tractive effort, others were also rebuilt to this standard. When Hughes introduced his classification system in 1919, the more powerful superheated locomotives were designated Class 6. The final examples were withdrawn in 1961.
The Midland Railway 2228 Class was a class of 0-4-4T side tank steam locomotive designed by Samuel Johnson. They were given the power classification 1P.
The LNWR 1185 Class was a class of 0-8-2T steam tank locomotives designed by Charles Bowen-Cooke and introduced in 1911. They passed into LMS ownership in 1923 and 8 survived to British Railways ownership in 1948. British Railways numbers were 47875-47896.
The LNWR 380 Class was a class of 0-8-4T steam tank locomotives designed by H. P. M. Beames. Although designed under the LNWR regime they appeared as LMS locomotives after the 1923 grouping. They were essentially an extended version of the 1185 Class 0-8-2T with a longer bunker, and were also related to the 0-8-0 freight engines. Their main area of work was to be in South Wales.
The London and North Western Railway (LNWR) Prince of Wales Class was a class of express passenger locomotive. It was in effect, a superheated version of the Experiment Class 4-6-0.
The London and North Western Railway (LNWR) George the Fifth Class was a class of 4-4-0 passenger steam locomotive.
The London and North Western Railway (LNWR) Prince of Wales Tank Class was a pacific tank engine version of the Prince of Wales Class 4-6-0 steam locomotive.
The London and North Western Railway (LNWR) Claughton Class was a class of 4-cylinder express passenger 4-6-0 steam locomotives.
The Midland Railway (MR) 1322 Class was a class of small 0-4-0ST steam locomotives designed for shunting. The next class of shunting engines built by the Midland was the 1116A Class, which was nearly identical.
The LNWR 317 class, consisted of a class of 20 square saddle-tanked steam locomotives built by the London and North Western Railway at their Crewe Works between 1896 and 1901. They had a very short coupled wheelbase, with a trailing Bissel truck to carry weight.
The London and North Western Railway (LNWR) 4ft Shunter was a class of 0-4-0ST steam locomotives. Introduced in 1863 by Ramsbottom, 26 were built in 1863–1865, 10 in 1870, 10 in 1872, and 10 in 1892. The last three of the latter batch were soon rebuilt as 0-4-2ST crane tanks. They survived into LMS ownership in 1923 and the last one was withdrawn in 1933.
The Caledonian Railway 179 Class was a class of 4-4-0 steam locomotives designed by George Brittain for the Caledonian Railway (CR) and introduced in 1882.
The Midland Railway 1532 class was a class of 65 0-4-4T locomotives built by Derby Works between 1881 and 1886 to the design of Samuel W. Johnson. They were a development of the 1252 class. Originally numbered 1532–1551, 1632–1656, and 1718–1737; under the 1907 renumbering scheme they became 1266–1330, and were given the power classification 1P.
The Midland Railway 1833 Class was a class of thirty 0-4-4T steam locomotives. They are sometimes included with the earlier 1823 Class or the later 2228 Class.
The LNWR 18-inch Goods was a class of 310 0-6-0 freight steam locomotives built by the London and North Western Railway at their Crewe Works between 1880 and 1902.
The LNWR 5ft 6in Tank was a class of 160 passenger 2-4-2T locomotives manufactured by the London and North Western Railway in their Crewe Works between 1890 and 1897. The "5ft 6in" in the title referred to the diameter of the driving wheels – although the stated dimension was for the wheel centres – the nominal diameter including the tyres was 5 ft 8+1⁄2 in (1,740 mm).
