LSWR 0298 Beattie Well Tank

Joseph Hamilton Beattie was locomotive superintendent of the London and South Western Railway from 1850 until his death in 1871, succeeded by his son William Beattie until 1878, when William Adams took over. The 0298 well tank was designed in late 1873 by William Beattie continuing his father's established pattern, and 30 engines were ordered from Beyer, Peacock & Co. of Manchester for delivery in 1874 and early 1875. The brief was a small suburban tank engine for the LSWR's heavy London commuter services, replacing earlier 0-4-0 well tanks of the 1850s and 1860s.

The well-tank arrangement (carrying water in a well between the frames rather than in side tanks) was favoured by Beattie because it kept the centre of gravity low and gave the engine a clean, narrow profile useful for short coupling sidings and for working through the LSWR's congested London terminals. The disadvantage was very limited water capacity, which restricted the class to short runs.

The 30 engines worked LSWR suburban services from Waterloo, Nine Elms, and the East London Railway connections through the late 1870s and 1880s. They were popular with their crews for free running and ease of maintenance, but were displaced from London work as Adams' 415 Class radial tanks (1882 onwards) and Drummond's M7 0-4-4 tanks (1897 onwards) took over the suburban duties. By 1900 most of the class had been withdrawn or sold to industrial users.

The class's significance in railway history is almost entirely due to the three engines that survived in service into the BR era to work the Wenford Bridge china clay branch. The branch ran from Boscarne Junction (near Bodmin) up the valley of the De Lank river to the clay works at Wenford, an isolated location in the Cornish moors. The line had been built as a horse tramway and incorporated very tight curves and unusual rail spacings; only a small, light, short-wheelbase engine could safely work it.

The first three Beattie well tanks were sent from London to Wadebridge in the early 1890s. They worked the branch alongside (and replaced) earlier Beattie 2-4-0 engines that had also been kept on this work. Their unusual longevity was simply because no successor design was sufficiently small and short for the curves on the upper branch. The Southern Railway considered replacement designs at various times in the 1920s and 1930s but always concluded that overhauling the existing well tanks was cheaper than redesigning a successor for a single light branch.

The three engines went through general overhauls at Eastleigh works in 1921, 1932, and 1949, on each occasion fitted with a new replacement boiler. They worked the branch through the inter-war period, the Second World War, and the early BR era. In 1962 BR finally found a successor that would fit: rebuilt GWR 1366 panniers, transferred from Wadebridge's sister depot. The Beattie well tanks worked their last trains on the branch in October 1962 after eighty-eight years in service.

30585 (formerly LSWR 0298, then 314, then SR 3314, then BR 30585) was built by Beyer, Peacock & Co. of Manchester in 1874. It worked LSWR Nine Elms suburban turns until the late 1890s, was sent to Wadebridge in 1895 (replacing earlier Beattie 2-4-0s already there), and worked the Wenford Bridge branch from then until withdrawal in 1962. After withdrawal it was preserved by the Quainton Railway Society and is currently based at the Buckinghamshire Railway Centre.

30587 (formerly LSWR 0298, then 298, then SR 3298, then BR 30587) was built by Beyer, Peacock & Co. in 1874 and shares an identical working history with 30585: Nine Elms suburban turns, transfer to Wadebridge in the 1890s, sustained service on the Wenford Bridge branch through to withdrawal in 1962. Preserved by the National Collection, it is now based at the Bodmin and Wenford Railway, the heritage line that runs over part of the route the class worked in service. 30587 is currently the only preserved Beattie well tank in working order.

30586 (formerly LSWR 0298, then 329, then SR 3329, then BR 30586) was the third Wenford engine. Built by Beyer, Peacock & Co. in 1874, it followed the same working pattern as 30585 and 30587. Withdrawn in 1962, it was scrapped at Eastleigh and is the only one of the three Wenford engines not to survive into preservation.

The class was originally turned out in LSWR pre-Drummond pea-green and brown, lined out in black-and-white. Drummond's reorganisation of the LSWR fleet in the 1890s brought olive green to the survivors, and the Southern Railway from 1923 painted them in plain Maunsell green and later wartime black. British Railways from 1948 painted the three Wenford engines in lined mixed-traffic black with the early lion-and-wheel emblem; the late ferret-and-dartboard crest was applied at general overhauls from the late 1950s. Both preserved engines have at various times carried BR mixed-traffic lined black and approximations of the LSWR Drummond olive green livery during their preservation careers.
