The North Staffordshire Railway (NSR) M Class was a class of 0-4-4T steam locomotive designed by John H. Adams, third son of William Adams. It was designed for suburban passenger work on the Potteries loop lines. They shared components such as a drumhead smokebox which rested on the saddle and an almost identical boiler with the NSR L class.^[1] The boiler of the M class later became a standard boiler for the NSR, it being used on the NSR's New L class and H class. The M class introduced a new form of cab roof which curved around to join the cab sides, as with the Midland Railway at the time, and was soon copied by the SE&CR.^[2] Five were built between 1907 and 1908 at the NSR's Stoke Works, with a further four built in 1920 at Stoke under John A. Hookham, who had succeeded Adams upon the latters death in 1915. This second batch had longer bunkers and Ross "pop" safety valves instead of Ramsbottom safety valves but were otherwise similar; they were known as the New M Class.^[3]

All entered the London, Midland and Scottish Railway (LMS) stock upon formation in 1923 with little modification, other than replacing the original Ramsbottom safety valves with Ross-pop type.^[1] With the LMS' policy of standardisation, many NSR classes were prime targets for early scrapping due to the small size of the classes. As a result, all save one was withdrawn by 1936, having been displaced by more modern six-coupled tanks. This last locomotive had the distinction of being the last NSR locomotive to remain in service save for a battery electric shunting engine, but by the final days was itself reduced to shunting duties.^[1]

The livery of the M class was the NSR's Madder Lake with straw lining, and NORTH STAFFORD lettering on the side tanks along with the company crest. The number appeared on the bunker. In LMS days all received the crimson lake passenger livery of the early LMS with large numerals on the side tanks and the company crest on the bunker, but by 1928 they were repainted in plain black with L M S written on the tanks and number on the bunker.^[1]

Withdrawal took place between 1930 and 1939.^[1] None survived into preservation.

The North Staffordshire Railway (NSR) was a British railway company formed in 1845 to promote a number of lines in the Staffordshire Potteries and surrounding areas in Staffordshire, Cheshire, Derbyshire and Shropshire.

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 L&YR Class 21 is a class of small 0-4-0ST steam locomotive built by the Lancashire and Yorkshire Railway for shunting duties. They were nicknamed Pugs.

The Belfast and Northern Counties Railway (BNCR) Class S was a class of 2-4-2T two-cylinder compound steam locomotives that was introduced for service on the 3 ft narrow gauge railways of County Antrim in north-east Ireland.

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 Northern Counties Committee (NCC) Class S1 was a class of two-cylinder compound 2-4-2T steam locomotives that was introduced for service on the 3 ft (910 mm) narrow gauge railways of County Antrim in north-east Ireland. The members of the class were rebuilds of the BNCR Class S.

The Northern Counties Committee (NCC) Class S2 was a solitary two-cylinder compound 2-4-4T steam locomotive that was introduced for service on the 3 ft narrow gauge railways of County Antrim in north-east Ireland. It was heavily rebuilt from a BNCR Class S locomotive by the addition of a standard gauge boiler.

The Belfast and Northern Counties Railway (BNCR) Class N was a class of 0-4-0ST dock engines that worked on the Belfast Harbour Commissioners' lines in north-east Ireland. No.42 was the first of the class and was built by Sharp, Stewart and Company in 1874. A second, similar engine, No.16, was built by the MR (NCC) in 1914.

The North Staffordshire Railway built or had constructed for it, approximately 350 locomotives. Until the company established Stoke railway works at Stoke-upon-Trent in 1864, a variety of engineering firms supplied locomotives. The company became more self-reliant as time went on, and by the beginning of the 20th century virtually all new engines were produced at Stoke works.

The Lancashire and Yorkshire Railway Class 32 was a small class of 0-8-2T steam locomotives, intended for heavy shunting and banking duties.

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 Glasgow and South Western Railway (GSWR) 131 class was a class of ten 0-4-2 steam locomotives designed in 1864. They were by Patrick Stirling's fifth 0-4-2 design for the railway.

The Glasgow and South Western Railway (GSWR) 141 class was a class of ten 0-4-2 steam locomotives designed in 1866. They were by Patrick Stirling's sixth 0-4-2 design for the railway.

The North Staffordshire Railway (NSR) New L Class was a class of 0-6-2T steam locomotives designed by John H. Adams, third son of William Adams. They were designed as a development as the previous L Class, adding a boiler common to the M Class and differed from the L Class with, amongst other things higher bunker sides and new cab roofs, and the abandonment of the cast safety valve cover. 28 were built between 1908 and 1923, with the final four constructed under the auspices of the newly formed LMS with the whole class withdrawn by the end of 1937. There is one survivor.

The North Staffordshire Railway (NSR) H1 Class was a class of 0-6-0 steam locomotive designed by John H. Adams, third son of William Adams. They were designed as a development as the previous H Class, adding a Belpaire firebox to a new design of boiler, which was similar to that of the NSR G class but with a reduced barrel length. Four were built between December 1910 and March 1911, all at the company's Stoke railway works. The whole class was withdrawn by the end of 1930, having quickly been displaced by the LMS 4F.

The North Staffordshire Railway (NSR) H Class was a class of 0-6-0 steam locomotive designed by John H. Adams, third son of William Adams. They were designed to replace aging 0-6-0 locomotives on NSR long distance goods and coal trains both on and off the NR network thanks to the NSR's extensive running powers. Four were built in December 1909 all at the company's Stoke railway works. The whole class was withdrawn by the beginning of 1930, owing to the small nature of the class. This small class was supplemented by an additional modified four, designated H1 class.

The North Staffordshire Railway (NSR) G Class was a class of 4-4-0 steam locomotives designed by John H. Adams, third son of William Adams. The G Class was the first 4-4-0 class of locomotive designed for the NSR, and they superseded older 2-4-0s on the heaviest passenger traffic expresses on the railway between Crewe and Llandudno non-stop. The NSR introduced bogie stock to this route in 1906, resulting in much heavier trains.

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).

The LNWR Newton Class was a class of ninety-six 2-4-0 steam locomotives built by the London and North Western Railway at their Crewe Works between 1866 and 1873.
