The Caledonian Railway 670 Class was a class of 0-4-2 steam locomotives designed by George Brittain for the Caledonian Railway (CR) and introduced in 1878.
The Highland Railway's Clan Class was a class of passenger 4-6-0 steam locomotives designed by Christopher Cumming. The design is derived from that of the slightly earlier Clan Goods although the similarity is more visual than real. The first four were built in 1919, and the remaining four in 1921.
The Highland Railway Ben Class were small 4-4-0 passenger steam locomotives. There were actually two separate 'Ben' classes, usually referred to as the 'Small Bens' and the 'Large Bens'.

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 The final examples were withdrawn in 1961.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 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 Caledonian Railway 439 Class is a class of 0-4-4T steam locomotive. It was a development of earlier Caledonian Railway 0-4-4T locomotives, including the 19 Class and 92 Class, and predecessor of the 431 Class. The 439 Class was introduced by John F. McIntosh in 1900 and a modified version was introduced by William Pickersgill in 1915.
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.

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 Lancashire and Yorkshire Railway Class 28 was a class of 0-6-0 steam locomotive, designed by George Hughes for the Lancashire and Yorkshire Railway (L&YR). It was a rebuild of Aspinall's Class 27, with the addition of a Belpaire firebox and the extension of the footplate and front sandboxes. It was similar, but had larger cylinders and a superheater. It had 5-foot-1-inch (1.549 m) wheels.
The Glasgow and South Western Railway (G&SWR) 403 Class was a class of 2-6-0 (mogul) steam locomotive designed by Peter Drummond, of which 11 were built in 1915 by the North British Locomotive Company at its Queens Park works. Originally built as the 403 class, as a result of renumbering they became known as the 33 Class in 1916 and then 51 Class in 1919, before passing to the London Midland and Scottish Railway (LMS) on its formation in 1923, where they were given power classification 4F.
The Caledonian Railway 264 and 611 classes were 0-4-0ST 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 GCR Class 9J was a class of 174 0-6-0 steam locomotives designed by John G. Robinson for freight work on the Great Central Railway (GCR) in 1901. They were a part of the Railway Operating Division during World War 1. The class acquired the nickname "Pom-Poms" due to the similarity of their exhaust noise to that of the "Pom-Pom" quick-firing gun used in the South African War.
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).
The L&YR Class 31 was a class of 0-8-0 steam locomotives of the Lancashire and Yorkshire Railway. The class was designed by George Hughes and introduced in 1912. The class comprised 115 new locomotives and 40 rebuilt from other classes.
The Caledonian Railway 721 Class was a class of 4-4-0 steam locomotives designed by John F. McIntosh for the Caledonian Railway (CR) and introduced in 1896. Taking their name from the estate in Perthshire owned by the Caledonian’s then deputy chairman, J.C.Bunten, all survived to be absorbed by the London, Midland and Scottish Railway (LMS) in 1923 and a few survived into British Railways (BR) ownership in 1948.
The Caledonian Railway 294 and 711 Classes were 0-6-0 steam locomotives designed by Dugald Drummond for the Caledonian Railway (CR) and introduced in 1883. After Drummond's retirement, construction of the class continued under Smellie, Lambie and McIntosh.
The Caledonian Railway 49 Class and 903 Class were 4-6-0 express passenger locomotives designed by John F. McIntosh and built at the Caledonian Railway's own St. Rollox Works in 1903 and 1906 respectively.
