Locomotives of the Southern Railway

The Southern Railway took a key role in expanding the 660 V DC third rail electrified network begun by the London & South Western Railway. As a result of this, and its smaller operating area, its steam locomotive stock was the smallest of the 'Big Four' companies. Yet its locomotives were unique and of great interest. For an explanation of numbering and classification, see British Rail locomotive and multiple unit numbering and classification.

Post-Nationalisation

British Railways completed construction of the 'West Country' and 'Merchant Navy' locomotive designs, but did not build any further orders. It abandoned the 'Leader' class experiments, and Bulleid left the UK to carry forward his unusual locomotive designs in Ireland.

Withdrawal

Withdrawal of ex-SR locomotives happened mainly towards the end of steam on the Southern Region (in 1967), the pre-Grouping designs having gone before then as electrification spread across the region.

Locomotives of SR Design

With the heavy emphasis on electrification for the London Suburban area and the Brighton main line there was little need for new steam locomotive designs. The main steam tasks were boat trains (Dover, Folkestone and Newhaven), West of England, Kent services and freight. When designing steam locomotives, the designers had some interesting constraints that dictated where the locomotive could be used. Due to the hangover from SE&CR days, most of the lines in Kent were of fairly light construction and would not take the weight of a modern express locomotive until well into the 1930s. Hence the extensive rebuilding (and new construction) of 4-4-0 designs at a time when other lines were busily building pacifics or heavy 4-6-0s.

The ex-SER lines also had the problem of the narrow Mountfield and Wadhurst tunnels on the Hastings Line, requiring locomotive and rolling stock rather narrower than permitted elsewhere. This problem persisted into British Railways days until eventually the tunnels were single tracked, giving clearance for normal stock.

Services for west of Southampton and Salisbury had a different set of problems as neither the Southern Railway nor its constituents installed water troughs, thus leading to large tenders with greater water capacity than those fitted to similar locomotives on other railways.

New designs were:

Richard E. L. Maunsell (1923–1937)

Maunsell also rebuilt, modified or continued the new construction of earlier classes

  • LSWR H15 class – Further production
  • LSWR N15 class – Further production
  • LSWR S15 class – Further production
  • LSWR M7 class – One superheated – not repeated
  • LSWR T9 class – Superheated
  • LSWR 700 class – Superheated
  • SECR B1 class
  • SECR D class as D1 class
  • SECR O class – rebuilt as O1 class
  • SECR N class – Further production
  • SECR N1 class – Three-cylinder derivative of N class
  • LB&SCR C2 class
  • LB&SCR L class 4-6-4T – rebuilt as 4–6–0 SR N15X class
  • LB&SCR E1 class 0-6-0T – rebuilt as 0-6-2T SR E1/R class
  • LB&SCR I1 class – rebuilt as I1X class

    • O. V. S. Bulleid (1937–1949)

  • SR Q1 class
  • SR Merchant Navy class (20 built by the Southern Railway, with 10 more by British Railways)
  • SR West Country and Battle of Britain classes: (70 built by the Southern Railway, with 40 more by British Railways)
  • SR Leader class: appeared after nationalisation

    • Bulleid was also responsible for the mechanical part of the three electric locomotives (CC1–CC3, later British Railways Class 70) built at Ashford Works in 1941 (CC1) and 1948 (CC2, CC3). The electrical part was the responsibility of the Southern Railway's Chief Electrical Engineer, Alfred Raworth. Bulleid also designed a 500 hp 0-6-0 diesel mechanical shunter powered by a Davey Paxman power unit. This was built at Ashford Works, though was not introduced until 1950, when it emerged as BR No. 11001.

    B. Cubitt (1842-1845)

    No SER locomotives built - stock administered by the London and Croydon, South Eastern, and London and Brighton Joint Locomotive Committee.

    James Cudworth (1845-1876)

  • White Horse of Kent, 2-2-2, introduced 1845, later rebuilt as a 2-4-0
  • SER 118 class 0-6-0 introduced 1855
  • SER 59 class 2-4-0 introduced 1857
  • SER Singles 2-2-2 introduced 1861
  • SER 235 class 0-4-4T introduced 1866

    • John Ramsbottom (1876)

  • SER Ironclads 2-4-0 introduced 1876

    • A. M. Watkin (1876)

  • SER 152 class 'Folkestone Tanks' 0-6-0T introduced 1877

    • Richard Mansell (1877-1878)

  • SER 58 class 'Mansell Gunboats' 0-4-4T introduced 1878
  • SER 59 class 'Mansell Goods' 0-6-0 introduced 1879

    • James Stirling (1878-1898)

    Stirling, like his brother Patrick, built engines with domeless boilers. Many, however, were rebuilt with domes in later years.

    London, Chatham and Dover Railway

    Initially LC&DR engines were given names, they only received numbers after 1874.

    On the merger with the South Eastern in 1898, engine numbers were increased by 459, this being the highest number in use on that line.

    South Eastern and Chatham Railway

    Before 1899, both the South Eastern Railway and the London, Chatham and Dover Railway had some Crampton locomotives built by Robert Stephenson and Company. The SER also had some Cramptons built by Tulk and Ley.

    H. S. Wainwright (1899–1913)

  • SECR B1 class 4-4-0 introduced 1900 rebuild of SER B Class
  • SECR F1 class 4-4-0 introduced 1903 rebuild of SER F Class
  • SECR O1 class 0-6-0 introduced 1903 rebuild of SER O Class
  • SECR R1 class 0-6-0T introduced 1910 rebuild of SER R Class

    • John Chester Craven (1847-1870)

    List of Craven locomotives

    William Stroudley (1870–1889)

    Many of these engines were later renumbered, frequently into the "duplicate" series above 600.

    D. Earle Marsh (1905–1911)

  • LB&SCR B2X class 4-4-0 introduced 1907 rebuild of B2
  • LB&SCR C2X class 0-6-0 introduced 1908 rebuild of C2
  • LB&SCR E4X class 0-6-2T introduced 1909 rebuild of E4
  • LB&SCR A1X class 0-6-0T introduced 1911 rebuild of A1
  • LB&SCR E5X class 0-6-2T introduced 1911 rebuild of E5
  • LB&SCR E6X class 0-6-2T introduced 1911 rebuild of E6

    • L. B. Billinton (1911–1922)

  • LB&SCR B4X class 4-4-0 introduced 1922 rebuild of B4
  • LB&SCR I1X class 4-4-2T introduced 1923 rebuild of I1

    • Following the grouping, LB&SCR locomotive numbers were prefixed with "B", but in 1931 the prefix was removed and 2000 added to the number.

    Diesel shunters

  • The Southern Railway built three diesel shunters in 1937, numbered 1–3. These became British Rail 15201–15203, and were later classified as British Rail Class D3/12.
  • Twenty-six similar locomotives were built in 1949–1951 after nationalisation. They were numbered 15211–15236, and were later classified as British Rail Class 12.
  • British Rail 11001, Southern Railway design, built 1949 at Ashford Works

    • Mainline diesels

  • The Southern designed a prototype class of mainline diesel-electric locomotive. Three were built, although none were finished before nationalisation. They were numbered 10201–10203, and later classified as British Rail Class D16/2.

    • Mainline electric

  • The Southern Railway also built two mainline electric locomotives numbered CC1 and CC2. They were renumbered 20001 and 20002 after nationalisation. A third locomotive, 20003, was built in 1948. They were later classified as British Rail Class 70
