The Highland Railway Drummond 0-6-4T or X class were large tank engines originally intended for banking duty. They were designed by Peter Drummond.
The first four were built by the North British Locomotive Company and delivered in 1909. A second batch of four was delivered in 1911.
The design was derived from that of the class K (0-6-0) tender engines and leading dimensions were very similar although the boiler and firebox are recorded as being 'larger' but by an unspecified amount.
They were not popular with their crews, many thought them heavy and clumsy, and several crews had problems with water capacity. It seems their axleboxes were not well-proportioned either as there are reports of consistent hot box problems.

They all survived to be taken over by the London, Midland and Scottish Railway (LMS) at the 1923 Grouping. The last was withdrawn in 1936.
The Locomotives of the Midland Railway, followed its small engine policy. The policy was later adopted by the London, Midland and Scottish Railway, and contrasted with the London and North Western Railway's policy. The small engine policy was partly the consequence of a difference in the background of senior managers. In most railway companies, the elite position was the design, construction and maintenance of locomotives. Bigger engines brought more prestige and allowed longer trains. In the Midland, the marketing department was paramount. They recognised that people wanted more frequent, shorter trains rather than an infrequent service. It concentrated on very light, very fast and frequent trains.
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 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 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 Highland Railway River class was a class of steam locomotive with a 4-6-0 wheel arrangement. They were designed by F. G. Smith, who had joined the Highland Railway in 1904 from the North Eastern Railway. His initial post was as manager of the Locomotive, Carriage and Wagon works at Inverness. When Peter Drummond departed to the Glasgow and South Western Railway at the end of 1911 Smith was appointed Chief Mechanical Engineer in his place.
The Highland Railway E Class was a class of 4-4-0 steam locomotive designed by David Jones for passenger service. They were also known as the 'Clyde Bogies' as they were built by the Clyde Locomotive Company in Glasgow, Scotland. They were the first locomotives built by that company.
The Highland Railway Jones Goods class was a class of steam locomotive, and was notable as the first class with a 4-6-0 wheel arrangement in the British Isles. Fifteen were built, and one has survived to preservation. Originally known as the Big Goods class, they became class I under Peter Drummond's 1901 classification scheme.
The Highland Railway W class were four small 0-4-4T locomotives built by the Highland Railway in 1905–1906 to the design of locomotive superintendent Peter Drummond. They were the last engines that were built at the company's Lochgorm works in Inverness, and were used on branch line services.
The Midland Railway (MR) 3835 Class is a class of 0-6-0 steam locomotives designed for freight work. The first two were introduced in 1911 by Henry Fowler. After the grouping in 1923, the designs were slightly modified and continued to be built up to 1941 by the LMS as the LMS Fowler Class 4F.
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 0-4-0 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 locomotives of the Glasgow and South Western Railway (G&SWR). The G&SWR had its headquarters in Glasgow with its main locomotive works in Kilmarnock.
The Lancashire and Yorkshire Railway (L&YR) Class 8 was a four-cylinder 4-6-0 express passenger locomotive designed by George Hughes introduced in 1908.
Locomotives of the Caledonian Railway. The Caledonian Railway Locomotive Works were originally at Greenock but moved to St. Rollox, Glasgow, in 1856. The locomotive classes are listed under the names of the railway's Chief Mechanical Engineers.
The locomotives of the Highland Railway were used by the Highland Railway to operate its lines in the north of Scotland. The Highland Railway locomotive works was at Lochgorm, Inverness. The works had been built about 1855 by the Inverness and Nairn Railway. The locomotive classes are listed under the names of the railway's Locomotive Superintendents.
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 Glasgow and South Western Railway 540 Class were 4-6-4T steam tank locomotives designed by Robert Whitelegg and built in 1922, shortly before the G&SWR was absorbed into the London, Midland and Scottish Railway (LMS). They were referred to in official G&SWR publicity as the Baltic Class, although they were also known more prosaically to enginemen as the 'Big Pugs'.
The Glasgow and South Western Railway (G&SWR) 279 class was a class of 0-6-0 steam locomotive designed by Peter Drummond, of which 15 were built in 1913 by the North British Locomotive Company at its Queen's Park works. Originally built as the 279 class, as a result of renumbering they became known as the 71 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 Glasgow and South Western Railway (G&SWR) 131 Class and 137 Class were two closely related classes of 4-4-0 steam locomotives designed by Peter Drummond. A total of 12 locomotives were built between 1913 and 1915, with some constructed by the North British Locomotive Company (NBL) at its Queens Park works and others by the G&SWR at its Kilmarnock works. Originally designated as the 131 and 137 classes, the locomotives were later renumbered and became known as the 331 and 325 classes, respectively, in 1919. Following the formation of the London Midland and Scottish Railway (LMS) in 1923, the locomotives were transferred to the LMS, where they were classified as 3P in terms of power rating.
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.
