    The LSWR 415 class is a steam tank locomotive of 4-4-2T wheel arrangement, with the trailing wheels forming the basis of its "Radial Tank" moniker. It was designed by William Adams and introduced in 1882 for service on the London and South Western Railway (LSWR).
    Originally rostered for suburban traffic, the class was soon displaced to the countryside by Dugald Drummond's M7 class. Most of the class was scrapped around the end of the First World War, and further decreases meant that all of them were due to be withdrawn by 1929. However, the class was noted for its long service on the Lyme Regis branch line, and three members of this long obsolete class were utilised on this duty until 1962, when suitable replacements became available
    This locomotive, designed by William Adams, was the result of the work made to replace the stop-gap 46 Class on suburban services around London. In the event, they were also intended to supplement this class while members entered the works for rebuilding into "Radial Tank" configuration. All were built from 1882, and were also intended for medium to heavy suburban passenger traffic around the South Coast on the LSWR railway network
    William Adams' 415 (later 0415) Class was based on his earlier LSWR 46 Class, and was specifically designed with London suburban services in mind. The design was based on a 4-4-0 design with a trailing axle added to support an enlarged coal bunker, a necessity for the intensive suburban services of the LSWR network. The radial axlebox worked in a corresponding curved hornblock the centre of which was struck near the middle of the chassis. The device was originally invented in 1863 by William Bridges Adams (no relation)[4] and could be applied to a leading or trailing axle but was generally preferred for the latter. Many other engineers used it, including Webb, R. J. Billinton, H. G. Ivatt, and D.E. Marsh. Many of the tank engines so fitted earned the soubriquet "Radial Tanks", or simply "Radials". The enlarged coal bunker was also designed to incorporate a back tank for extra water storage in addition to the capacity of the side tanks. Valve gear was of modified Stephenson type.
    Production began in 1882 when a total of four engineering companies were contracted by the LSWR to construct the new class, which numbered 71 when production ceased in 1885.[3] These were: Robert Stephenson & Co. (28 constructed); Dübs & Co. (20 constructed); Neilson & Co. (11 constructed) and finally Beyer, Peacock and Company (12 constructed).[2] This arrangement was because Nine Elms, the LSWR's own locomotive works, was already stretched to capacity in terms of production
    Although all were constructed to the same basic design, the locomotives that were outshopped from 1884 had slightly larger side water tanks and deeper fireboxes, therefore increasing efficiency.[3] All carried the trademark Adams stove pipe chimney throughout his tenure as Locomotive Superintendent of the LSWR.[3] In order to facilitate the speedy overhaul of these locomotives in the confined spaces of Nine Elms, spare boilers were constructed. Coupled to a short wheelbase and guiding bogies, the locomotive was relatively manoeuvrable on tight curves, a feature that was to ensure the survival of some of the class later on.
    Upon the appointment of Dugald Drummond as Superintendent of the LSWR after Adams' departure, the class was modified slightly, with the application of his lipped chimney in place of the stovepipe version that the locomotives were equipped with when built. This also coincided with the addition of coal rails to the bunker in an attempt to increase capacity. Because the class was not considered to have a long working life under Robert Urie, they were not equipped with superheating
    Despite being well received in service by locomotive crews, the 0415's tenure on the London suburban services was relatively short-lived. This was especially true with the introduction of the Adams T1 class of 0-4-4 tanks displacing some of the class from the London area. However, it was not until the introduction of Drummond's M7 class 0-4-4 tanks and electrification of the suburban railway network that the class was generally removed from the London section of the LSWR to rural branch duties from 1895.
    Despite this, in 1903 the inextricable link was made between the class and the severely curved Lyme Regis branch. Unsuccessful trials were carried out with the Stroudley Terriers and the Adams O2 class; however with the trailing axle modified[5] the flexible 0415 class tanks proved to be highly suited to the operating conditions of that line. As a result, two were allocated to Exmouth Junction shed for the Axminster to Lyme Regis service, joined in 1946 by a third example retrieved from the East Kent Railway
