The Caledonian Railway 294 and 711 Classes (nicknamed "Jumbo") 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. [1] [2]
All 244 locomotives survived to be absorbed by the London, Midland and Scottish Railway (LMS) in 1923 and 238 survived into British Railways (BR) ownership in 1948.

The BR number series are not continuous because some locomotives were withdrawn before 1948.
The steam locomotives of British Railways were used by British Railways over the period 1948–1968. The vast majority of these were inherited from its four constituent companies, the "Big Four".
The London, Midland and Scottish Railway (LMS) Fairburn Tank 2-6-4T is a class of steam locomotive. They were designed by Charles E. Fairburn for the LMS. 277 of these locomotives were built between 1945 and 1951, numbered in the range 42050–42186, (4)2187–(4)2299, (4)2673–(4)2699.
The Caledonian Railway 812 and 652 Classes were 0-6-0 steam tender locomotives designed by John F. McIntosh for the Caledonian Railway and introduced in 1899. They had the same boiler type as the 721 “Dunalastair” Class 4-4-0s. They could reach speeds of up to 55 mph (89 km/h).
The Caledonian Railway 300 Class were freight 0-6-0 tender engines introduced in 1918 and designed by William Pickersgill. Forty-three were built between 1918 and 1920. They were numbered 294–324, 280, 281, 670–679 by the Caledonian Railway.
The Highland Railway's Clan Goods class was a class of steam locomotive. They were designed by Christopher Cumming. The first four were built by Hawthorn Leslie and Company on Tyneside, and the maker's plates bore the date 1917, but because of wartime delays were not delivered until 1918. Four more were built in 1919, also by Hawthorn Leslie.
The Highland Railway K class were the only class of 0-6-0 tender locomotives built for the Highland Railway. They were introduced in 1900, to the design of Peter Drummond. The class were known as 'Barneys'.
The Lancashire and Yorkshire Railway Class 25 is a class of 0-6-0 steam locomotive. They were introduced to the Lancashire and Yorkshire Railway in 1876 by new locomotive superintendent William Barton Wright and 280 were built in total. Of these, 230 were later converted to saddle tanks by John Aspinall, to become L&YR Class 23. They were nicknamed "Ironclads" after the ships of the same name being developed at the time.
The North British Railway (NBR) G Class is a class of 0-4-0ST steam locomotive designed for shunting. Some locomotives were equipped with small wooden tenders to carry extra coal. They were introduced in 1882 and thirty-eight entered service on the NBR between 1882 and 1899. Like most 0-4-0 tanks of the period it has outside cylinders and inside slide valves driven by Stephenson valve gear. The rival Caledonian Railway had the same number (38) of identical locomotives in service. The nickname "Pug" was used on the NBR.
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.
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.
The Caledonian Railway 498 Class was a class of 0-6-0Ts built for dock shunting. They were designed by John F. McIntosh for the Caledonian Railway (CR) and introduced in 1911. Twenty-three were built. They passed to the London, Midland and Scottish Railway (LMS) in 1923 and to British Railways (BR) in 1948. Their numbers are shown in the table below.
Caledonian Railway Single No. 123 is a preserved Scottish steam locomotive. The unique 4-2-2 was built by Neilson and Company in 1886, works No. 3553, as an exhibition locomotive. In 1914 it was placed on the Caledonian Railway duplicate list, and renumbered 1123. It entered London, Midland and Scottish Railway service in 1923 and the LMS renumbered it 14010 and gave it the power classification 1P. During the 1920s it was allocated to working the directors' saloon, but it was returned to ordinary service in 1930. The locomotive was withdrawn in 1935, by which time it was the last single-wheeled express engine running in Britain, and set aside for preservation.
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 782 Class was a class of 0-6-0T steam locomotives designed by John F. McIntosh and introduced in 1896. The 29 Class was similar but fitted with condensing apparatus. The locomotives were taken into London, Midland and Scottish Railway (LMS) ownership in 1923 and into British Railways (BR) ownership in 1948.
The LB&SCR D1 class were powerful 0-4-2 suburban passenger tank locomotives, designed by William Stroudley of the London Brighton and South Coast Railway in 1873. They were originally known as "D-tanks" but later reclassified as class D1. Members of this very successful class survived in service until 1951.
Caledonian Railway 0-4-4T steam locomotives were built for the Caledonian Railway, in Scotland, over many years. Most survived into London, Midland and Scottish Railway (LMS) ownership in 1923 and some into British Railways (BR) ownership in 1948. Designers included Dugald Drummond, John Lambie, John F. McIntosh and William Pickersgill. A development of the Pickersgill design was introduced by the LMS in 1925.
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 G&SWR 45 Class were 0-6-2T steam locomotives designed by Peter Drummond for the Glasgow and South Western Railway (G&SWR) of which 18 were built in 1915-1917, followed by a further 10 of a slightly modified design in 1919 after Robert Whitelegg took over as Chief Mechanical Engineer.
The Caledonian Railway 944 Class were 4-6-2T passenger tank locomotives designed by William Pickersgill and built in 1917, at the North British Locomotive Company's Hyde Park Works in Glasgow. They were the Caledonian Railway's only Pacific-type.
