The LSWR P14 class was a class of 4-6-0 locomotive designed by Dugald Drummond for the London and South Western Railway.
The continuing need to grasp the nettle in terms of Drummond's first two 4-6-0 classes meant that he went back to the drawing board to create another design. The LSWR's immediate traffic needs were covered by the relatively successful G14 design of 1908, though with only five locomotives in the class, they were unable to undertake the haulage of all heavy boat train services. [1] [ page needed ] However, the problem of continually accelerating timetables to the South Coast ports remained, and the G14s were in dire need of assistance from a new class of similar design. [1] [ page needed ]
The design's proven ability to ply their trade at faster speeds, and their inherent larger power-to-weight ratio on other lines meant that Drummond once again decided to persevere with the concept. [1] [ page needed ]
On his penultimate 4-6-0 design, Drummond had to produce a locomotive that was capable of hauling increased traffic at speed. Once again, the possible advantages of the design presented themselves. [2] A similar boiler to the other classes, rated to 175 lbf/in² saturated steam pressure, was utilised, therefore generating the steam needed to power a four-cylinder front end, which powered 6 ft wheels. [1] [ page needed ] The new design was equipped with four sets of Walschaerts valve gear, therefore reducing the mechanical complexity that had plagued his previous designs. [2] This factor also meant a marginally lighter axle-loading. Large, single splashers were also implemented which covered the wheels, though these would prove troublesome in service. [1] [ page needed ] 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 P14s being outshopped in 1910, two years after the completion of his G14 design. [1] [ page needed ]

After a period of 15 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 the class needed to be rebuilt to conform with the general standardization of Southern locomotive classes. [3] [ page needed ] The P14s were reduced to kits of parts, which were utilised in creating a further batch of N15 (King Arthur Class) locomotives [4] [ page needed ]. However 0449 (renumbered to make way for the new N15) ran for several months, as part of the development work for the Lord Nelsons, at the same time of its alleged rebuild as the new N15 449 was running in. [5]
Under the LSWR, the P14s were outshopped in the LSWR Passenger Sage 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. [6] [ 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. [3] [ page needed ]
The P14 design had originally been intended to operate expresses between Salisbury and Exeter, replacing the failed F13 and E14 predecessors. They were considered to be more successful than these locomotives by their crews, and acted as supplements to their G14 class siblings on these duties. [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 P14s continued in their Drummond guise without modification until they were rebuilt in 1925 by Richard Maunsell, who used the parts to create a new batch of N15 locomotives. [1] [ page needed ] As a result, no examples survived into preservation.
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 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 eight 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.
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 was 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 700 class was a class of 30 0-6-0 steam locomotives designed for freight work. The class was designed by Dugald Drummond in 1897 for the London and South Western Railway in England and built by Dübs and Company at that company's Queen's Park works at Polmadie, Glasgow, Scotland.
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 G14 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 LSWR G16 class was a class of steam tank locomotives with a 4-8-0T wheel arrangement. It was designed by Robert Urie and introduced in 1921 specifically for heavy shunting over humps at Feltham marshalling yard, on the London and South Western Railway (LSWR). They were based upon Urie's previous S15 class freight design, and apart from several periods of operating elsewhere on the LSWR and Southern railway network, they remained at Feltham for most of their operational careers.
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.
