The London, Brighton and South Coast Railway E4 class is a class of 0-6-2T side tank steam locomotive designed by Robert Billinton. They were introduced in 1897 and were essentially a larger version of the E3 Class. The cylinder diameter was reduced from 18to by the Southern Railway.
75 members of the class were built by Brighton railway works between December 1897 and September 1903. The "radial tanks" were powerful for their size and were common on local passenger, freight and branch work for more than fifty years. They were very similar to the E3 tank engines from 1891, but the key differences were that their driving wheels were enlarged from to and their boiler pressure was increased to . Several were named after towns, villages and geographical features in the LB&SCR area, for example No. 469 Beachy Head. Some of their names would be re-used for H2 Atlantics a few years later.[1] They were so successful that they were more commonly assigned to passenger trains instead of the freight work they were originally intended for.
During World War I the Railway Operating Division (ROD) borrowed several members of the class (Nos. 470, 481, 498, 504, 506, 518, 519, 562, 563, 564, 565, 577 and 580) for work in France. They first worked at an ammunition dump in Audruicq in November 1917 and were later sent to the Arras area in February 1918.[2] [3] All of them were returned to England in 1919. After Grouping they were primarily to be found around the Central section of the Southern Railway, with some going away from their traditional routes to places like Waterloo, Eastleigh and Tonbridge.[4]
All of the class entered Southern Railway ownership in 1923. One example, No. 2483 Hellingly, was severely damaged as a result of enemy action against Eastbourne motive power depot in 1942 during a Luftwaffe air raid event known as the Baedeker Blitz.[5] [6] Hellingly was scrapped in July 1944.[7] [8] One engine, No. 2510, was unsuccessfully tested on the railways of the Isle of Wight in 1947. The class continued in regular use following the nationalisation of the Southern Railway as part of British Railways in 1948. However, with the arrival of diesel multiple unit and the reduction in the number of branch lines after The Reshaping of British Railways in 1963, the locomotives gradually became surplus to requirements, and withdrawals commenced in 1955. Most of the class were withdrawn between 1958 and 1964.
The E4 class were initially used on local passenger and freight services, and on branch lines. Later in British Railways use, several examples were used as station pilots, most famously at London Waterloo, where they brought empty carriage rakes into the station from the yards at Clapham Junction. They were also used on services such as the locally famous Lancing Belle, which ran from Brighton to the former LB&SCR's Lancing Carriage Works, often double-headed with members of the same class or the larger E6 class.
British Railways (BR) numbers were 32463-32520, 32556-32566 and 32577-32582.
In 1909, four locomotives were rebuilt by D. E. Marsh with larger boilers and designated E4X. These became BR numbers 32466, 32477, 32478 and 32489.
One of the last members was No. 32473 in 1963. This was purchased by a group of preservationists and brought to the Bluebell Railway in East Sussex where it has remained ever since, except for visits to other lines such as the Severn Valley Railway and Isle of Wight Steam Railway. The engine was withdrawn from traffic in 1971 and dismantled. However work did not start in earnest until the 1980s and following a long overhaul, it returned to traffic in 1997 to celebrate its centenary in 1998.
After a short period running period-accurate post-1912 LB&SCR livery with the company's initials painted on the side tanks,[10] these were re-lettered with its earlier name Birch Grove. In 2005, it was repainted into British Railways lined black mixed traffic livery. Following withdrawal from service in May 2008, the locomotive was soon brought into the Bluebell workshops for a fast track overhaul, including a repaint into 1920s Southern Railway green to match much of the line's coaching stock. This was completed during January 2010, with the engine reentering traffic on 30 January. 32473 is the only preserved LB&SCR locomotive not designed by William Stroudley.
Bachmann Branchline produced several ready to run OO gauge models of the E4 tank including examples in SR olive green, BR black and LBSCR Marsh umber livery.[11]
