The LSWR G14 class was a class of 4-6-0 locomotive designed by Dugald Drummond for the London and South Western Railway.
The continuing need to improve upon Drummond's first two 4-6-0 classes meant testing out a new design based on their failures. The LSWR's immediate traffic needs could not be covered by the relatively unsuccessful E14 class of 1907, and the first Drummond 4-6-0 – the F13 class of 1905 – had been withdrawn from the heavy passenger services they were designed to undertake, as they would not 'run' and were heavy on coal, water and man-hours in terms of upkeep. [1] [ page needed ] However the problem of continually accelerating timetables to the South Coast ports remained, and any further engines of the E14 class could not be relied upon to uphold the heavy passenger services alone. [1] [ page needed ]
It was still clear that another 4-6-0 design was needed to bolster the strength of heavy express passenger locomotives available to the LSWR's operating department. [1] [ page needed ] Their proven ability to pull heavy trains at faster speeds and their inherently better power-to-weight ratio on other lines made Drummond decide to continue with the concept. [1] [ page needed ] He also retained the four-cylinder layout, resulting in what became the G14 class. [1] [ page needed ]
Drummond decided to continue his development of the 4-6-0 wheel arrangement in anticipation of further increases in the speed and length of trains, a concept with many advantages that he incorporated in his third design of this type. A 175 psi (1.21 MPa) saturated boiler, somewhat smaller than on the F13/E14 classes, was utilised to power the four-cylinder front end. [1] [ page needed ]
The new design was equipped with inside and outside sets of Walschaerts valve gear, therefore reducing the mechanical complexity that had plagued his previous designs, and these powered 6 ft (1.8 m) wheels. [2] This factor also meant a slightly lighter axle-loading compared to the mixed Stephenson/Walschaerts F13 class. Large single splashers that covered the wheels were also implemented, though these would prove troublesome in service. The Drummond 'watercart' eight-wheeled tender was utilised for the long journeys on the LSWR mainline. Full-scale construction was undertaken at Nine Elms, with the first of five G14s being outshopped in 1908.

After 17 years in both primary and secondary passenger duties, Richard Maunsell, who became Chief Mechanical Engineer of the newly formed Southern Railway in 1923, decided that as the class did not conform with the general standardization of Southern locomotive classes it should be withdrawn. [1] [ page needed ] The G14s were reduced to kits of parts, some of which may have been utilised in creating a further batch of N15 (King Arthur Class) locomotives. [3] [ page needed ]
Under the LSWR, the G14s were outshopped in the LSWR Passenger Royal Green livery with purple-brown edging, creating panels of green. [1] [ page needed ] This was further lined in white and black with 'LSWR' in gilt on the tender tank sides.
When transferred to Southern Railway ownership after 1923, the locomotives were outshopped in Richard Maunsell's darker version of the LSWR livery. [4] [ page needed ] The LSWR standard gilt lettering was changed to yellow with 'Southern' on the water tank sides. The locomotives also featured black and white lining. [5] [ page needed ]
The G14 design was originally intended to operate expresses between Salisbury and Exeter, and were considered more successful than their F13 and E14 predecessors. [1] [ page needed ] However, the class still had most of the drawbacks associated with Drummond 4-6-0s in terms of high water and coal consumption. [1] [ page needed ]
The G14s continued in their original state without modification until they were withdrawn in 1925 by Richard Maunsell, who put their watercart tenders and numbers to use in new N15 class locomotives. [1] [ page needed ] All members of the class were scrapped.
The LSWR/SR H15 class was a class of 2-cylinder 4-6-0 steam locomotives designed by Robert Urie for mixed-traffic duties on the LSWR. Further batches were constructed by Richard Maunsell for the Southern Railway after 1923. They were given the nickname of "Junior King Arthur" due to the size of their driving wheels, the S15 and their N15 cousins had driving wheels which had a diameter of 5 foot and 7 inches and 6 foot and 7 inches respectively.
The SR Class W were 3-cylinder 2-6-4T tank engines designed in 1929 by Richard Maunsell for use on the Southern Railway. They were introduced in 1932 and constructed at Eastleigh and Ashford. The class was intended for short distance, inter-company/regional freight traffic transfer in London, and were standardised with parts from the N, N1, U and U1 classes.
The SR N15X class or Remembrance class were a design of British 4-6-0 steam locomotives converted in 1934 by Richard Maunsell of the Southern Railway from the large LB&SCR L class 4-6-4 tank locomotives that had become redundant on the London–Brighton line following electrification. It was hoped that further service could be obtained from these locomotives on the Southern's Western Section, sharing the duties of the N15 class locomotives. The locomotives were named after famous Victorian engineers except for Remembrance, which was the LBSCR's memorial locomotive for staff members who died in the First World War.
The LSWR N15 class was a British 2–cylinder 4-6-0 express passenger steam locomotive designed by Robert Urie. The class has a complex build history spanning three sub-classes and ten years of construction from 1918 to 1927. The first batch of the class was constructed for the London and South Western Railway (LSWR), where they hauled heavy express passenger trains to the south coast ports and further west to Exeter. After the Lord Nelsons, they were the second biggest 4-6-0 passenger locomotives on the Southern Railway. They could reach speeds of up to 90 mph (145 km/h).
The SR V class, more commonly known as the Schools class, is a class of steam locomotive designed by Richard Maunsell for the Southern Railway. The class was a cut down version of his Lord Nelson class but also incorporated components from Urie and Maunsell's LSWR/SR King Arthur class. It was the last locomotive in Britain to be designed with a 4-4-0 wheel arrangement, and was the most powerful class of 4-4-0 ever produced in Europe. All 40 of the class were named after English public schools, and were designed to provide a powerful class of intermediate express passenger locomotive on semi-fast services for lines which could cope with high axle loads but some of which had short turntables.
The LSWR M7 class is a class of 0-4-4T passenger tank locomotive built between 1897 and 1911. The class was designed by Dugald Drummond for use on the intensive London network of the London and South Western Railway (LSWR), and performed well in such tasks. Because of their utility, 105 were built and the class went through several modifications over five production batches. For this reason there were detail variations such as frame length. Many of the class were fitted with push-pull operation gear that enabled efficient use on branch line duties without the need to change to the other end of its train at the end of a journey.
The LSWR S15 class is a British 2-cylinder 4-6-0 freight steam locomotive designed by Robert W. Urie, based on his H15 class and N15 class locomotives. The class had a complex build history, spanning several years of construction from 1920 to 1936. The first examples were constructed for the London and South Western Railway (LSWR), where they hauled freight trains to the south coast ports and further west to Exeter, as well as occasional passenger work in conjunction with their larger-wheeled N15 class counterparts.
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 London and South Western Railway L11 class was a class of 4-4-0 steam locomotives designed for mixed traffic work. They were introduced in 1903 and were nicknamed "Large Hoppers". As with most other Drummond productions, the locomotive had two inside cylinders and Stephenson link valve gear.
The London and South Western Railway L12 class was a class of 20 4-4-0 steam locomotives designed for express passenger work by Dugald Drummond. They were introduced to the London and South Western Railway network in 1904. Despite the class being an unremarkable continuation of the Drummond lineage, one member was involved in the infamous Salisbury rail crash in June 1906. None of the class survived into preservation after their brief career in British Railways ownership.
The London and South Western Railway K10 Class was a class of 40 4-4-0 steam locomotives designed for mixed traffic work. They were introduced on the London and South Western Railway in 1901 and 1902 to the design of Dugald Drummond, where they earned the nickname "Small Hoppers".
The London and South Western Railway T9 class is a class of 66 4-4-0 steam locomotive designed for express passenger work by Dugald Drummond and introduced to services on the LSWR in 1899. One example has been preserved after British Railways ownership. They were given the nickname of "Greyhounds" due to their speed, up to 85 miles per hour (137 km/h), and reliability.
The LSWR G6 class was an 0-6-0T tank locomotive designed by William Adams for the London and South Western Railway.
The LSWR Class S11 was a class of 10 4-4-0 steam locomotives designed for express passenger work by Dugald Drummond. They were introduced to services on the London and South Western Railway in 1903. None of the class survived into preservation after their brief career in British Railways ownership.
The London and South Western Railway F13 class was a class of 4-6-0 locomotives designed by Dugald Drummond for the London and South Western Railway (LSWR).
The LSWR Class T14 was a class of ten 4-6-0 locomotives designed by Dugald Drummond for express passenger use on the London and South Western Railway and constructed at Eastleigh in 1911–12.
The LSWR E14 Class was a class of 4-6-0 locomotive designed by Dugald Drummond for the London and South Western Railway.
The LSWR P14 class was a class of 4-6-0 locomotive designed by Dugald Drummond for the London and South Western Railway.
The LSWR D15 class 4-4-0 was the last steam locomotive design by Dugald Drummond for the London and South Western Railway in 1912. By 1912, Dugald Drummond had built several classes of unsuccessful 4-6-0 express passenger locomotives. The result of these failures was that when he designed what was to be his last class in 1911, a new 4-4-0 design emerged from Eastleigh Works in February 1912, with what was to be the first of his D15 class.
The SECR K class was a type of 2-6-4 tank locomotive designed in 1914 by Richard Maunsell for express passenger duties on the South Eastern and Chatham Railway (SECR), which operated between London and south-east England. The Southern Railway (SR) K1 class was a three-cylinder variant of the K class, designed in 1925 to suit a narrower loading gauge. They were among the first non-Great Western Railway (GWR) types to use and improve upon the basic design principles of power and standardisation established by GWR Chief Mechanical Engineer (CME) George Jackson Churchward. The locomotives were based on the GWR 4300 class, improved by the Midland Railway's ideals of simplicity and ease of maintenance.
