The SECR J class was a class of 0-6-4T steam tank locomotive built for heavy freight service on the South Eastern and Chatham Railway, by Harry Wainwright.

Contents

History

The South Eastern and Chatham Railway (SECR) had a need for versatile mixed traffic locomotives which could accelerate quickly so as not to impede the heavy passenger traffic on the densely used lines around London. Following the success of his C class 0-6-0 and his H class 0-4-4T Harry Wainwright sought to combine their good features but was limited by weight restrictions on many lines. The result was an 0-6-4 tank. [1] Five locomotives were constructed at Ashford during 1913, but Wainwright retired soon afterwards and no more were constructed. The class were moderately successful on a variety of secondary passenger and freight services. All had completed more than one million miles at the time of their withdrawal between 1949 and 1951. [2]

Numbering

The class were originally allocated unused numbers between 126 and 614. However, all but number 597 were renumbered by the Southern Railway in 1927/8 to create a unified sequence from A596 to A599. These later became 1596–1599, and then 31596–31599 under British Railways.

Southern Railway (UK) British “Big 4” railway company, active 1923–1947

The Southern Railway (SR), sometimes shortened to 'Southern', was a British railway company established in the 1923 Grouping. It linked London with the Channel ports, South West England, South coast resorts and Kent. The railway was formed by the amalgamation of several smaller railway companies, the largest of which were the London & South Western Railway (LSWR), the London, Brighton and South Coast Railway (LB&SCR) and the South Eastern and Chatham Railway (SE&CR). The construction of what was to become the Southern Railway began in 1838 with the opening of the London and Southampton Railway, which was renamed the London & South Western Railway.

South Eastern and Chatham Railway

The South Eastern and Chatham Railway Companies Joint Management Committee (SE&CRCJMC), known as the South Eastern and Chatham Railway (SE&CR), was a working union of two neighbouring rival railways, the South Eastern Railway (SER) and London, Chatham and Dover Railway (LC&DR), which operated between London and south-east England. Between 1899 and 1923, the SE&CR had a monopoly of railway services in Kent and to the main Channel ports for ferries to France and Belgium.

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.

SR W class

The SR Class W were 3-cylinder 2-6-4T tank engines designed in 1929 by Richard Maunsell for use on the Southern Railway. They were introduced in 1932 and constructed at Eastleigh and Ashford. The class was intended for short distance, inter-company/regional freight traffic transfer in London, and were standardised with parts from the N, N1, U and U1 classes.

Ashford railway works was in the town of Ashford in the county of Kent in England.

SECR C class

The South Eastern and Chatham Railway (SECR) C Class is a class of 0-6-0 steam locomotive, designed by Harry Wainwright and built between 1900 and 1908. They were designed for freight duties, although occasionally used for passenger trains. They operated over the lines of the railway in London and south-east England until the early 1960s. One example was rebuilt as an S Class saddle tank.

SECR P class

The South Eastern and Chatham Railway (SECR) P Class is a class of 0-6-0T steam locomotive designed by Harry Wainwright.

SECR H class

The South Eastern and Chatham Railway (SECR) H Class is a class of 0-4-4T steam locomotive originally designed for suburban passenger work, designed by Harry Wainwright in 1904. Most of the sixty-six members of the class were later equipped for push-pull working for use on rural branch lines.

Harry Smith Wainwright was an English railway engineer, and was the Locomotive, Carriage and Wagon Superintendent of the South Eastern and Chatham Railway from 1899 to 1913. He is best known for a series of simple but competent locomotives produced under his direction at the company's Ashford railway works in the early years of the twentieth century. Many of these survived in service until the end of steam traction in Britain in 1968, and are regarded as some of the most elegant designs of the period.

SER O class

The South Eastern Railway (SER) O Class was a class of 0-6-0 steam locomotive designed for freight work, and were the main freight engines of the SER, and later the South Eastern and Chatham Railway (SECR) for a number of years. However, they were displaced by the more powerful C class locomotives following the amalgamation of the South Eastern Railway and London, Chatham and Dover Railway (LCDR) in 1899. This relegated the class to working on the numerous branch lines in Kent, on both passenger and freight work. They worked most notably on the Kent & East Sussex Railway and East Kent Railway, operating coal trains from the Kent coal fields to London, as well as shunting work at such locations as Shepherds Well, Hoo Junction and Ashford. The majority were withdrawn before the outbreak of the Second World War in 1939, and those that remained were slowly withdrawn from nationalisation onwards.

SECR N class Class of English steam locomotives

The SECR N class was a type of 2-6-0 ("mogul") steam locomotive designed in 1914 by Richard Maunsell for mixed-traffic duties on the South Eastern and Chatham Railway (SECR). Built between 1917 and 1934, it was the first non-Great Western Railway (GWR) type to use and improve upon the basic design principles established by GWR Chief Mechanical Engineer (CME) George Jackson Churchward. The N class was based on the GWR 4300 Class design, improved with Midland Railway concepts.

Longhedge railway works was a locomotive and carriage works built by the London, Chatham and Dover Railway in the borough of Battersea, South London to serve their new London terminus at Victoria. The facility existed between 1862 until the mid-1950s.

SECR D class

The SECR D class is a class of 4-4-0 tender locomotives designed by Harry Wainwright for the South Eastern and Chatham Railway.

SECR N1 class

The SECR N1 class was a type of 3-cylinder 2-6-0 ('mogul') steam locomotive designed by Richard Maunsell for mixed traffic duties, initially on the South Eastern and Chatham Railway (SECR), and later operated for the Southern Railway (SR). The N1 was a development of the basic principles established by the Great Western Railway's (GWR) Chief Mechanical Engineer (CME) George Jackson Churchward and by Maunsell's previous N class design.

SECR L class

The SECR L class was a class of 4-4-0 steam tender locomotive built for express passenger service on the South Eastern and Chatham Railway. Although designed by Harry Wainwright, they were built during the Maunsell era.

SECR B1 class

The SECR B1 class was a class of 4-4-0 steam tender locomotive for express passenger service on the South Eastern and Chatham Railway. These engines were originally designed by James Stirling for the South Eastern Railway (SER) in 1898 and designated B class. The SER was merged into the SECR in 1899 and, between 1910 and 1927 the B class engines were rebuilt with new boilers by Harry Wainwright to become B1 class.

SECR K and SR K1 classes Two classes of 20 two-cylinder (K) and 1 three-cylinder (K1) 2-6-4T locomotives

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.

SR L1 class

The Southern Railway L1 class was a class of 4-4-0 steam tender locomotives built for express passenger service on the South Eastern Main Line of the Southern Railway. They were designed by Richard Maunsell as a development of Harry Wainwright's L class.

SECR E class
