SR Class W
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. Background From the 1920s London was surrounded by a number of large freight Marshalling yards, where long-distance freight trains were brought and re-organised into new trains for onward transmission to their destinations. Three of these yards, at Feltham, Norwood and Hither Green, were operated by the Southern Railway. The requirement for a fast freight transfer locomotive between these yards, and across London to other railway yards, provided a challenge for Richard Maunsell. The electrified suburban lines were busy with commuter traffic which took priority over freight workings, and the London network abound ...

Richard Maunsell
Richard Edward Lloyd Maunsell (pronounced "Mansell") (26 May 1868 – 7 March 1944) held the post of chief mechanical engineer (CME) of the South Eastern and Chatham Railway from 1913 until the 1923 Grouping and then the post of CME of the Southern Railway in England until 1937. He had previously worked his way up through positions in other railways in Ireland, England and India. Biography He was born on 26 May 1868 at Raheny, County Dublin, in Ireland, the seventh son of John Maunsell, a Justice of the Peace and a prominent solicitor in Dublin. He attended The Royal School, Armagh from 1882 to 1886. He commenced studies at Trinity College, Dublin on 23 October 1886 for a law degree; however by this stage he had shown a keen interest in engineering. He concurrently began an apprenticeship at the Inchicore works of the Great Southern and Western Railway (GS&WR) under H. A. Ivatt in 1888. Following completion of his degree in January 1891 he was able to complete his appr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feltham Marshalling Yard
Feltham marshalling yard, also known as Feltham hump yard, was a large railway marshalling yard designed for the concentration of freight traffic to and from South West London, and for transfer to other marshalling yards in London. It was built on the Waterloo to Reading Line. It opened in 1918 and was closed by British Railways on 6 January 1969. Part of the site is now being rebuilt to stable Class 701 electric multiple unit trains for South Western Railway (SWR). History During the early years of the twentieth century, the London and South Western Railway (LSWR) experienced a substantial growth in its freight traffic to and from London, and for transfer to other railways. By 1910 this traffic was beginning to overwhelm the existing facilities at Nine Elms. Plans were therefore made for a hump marshaling yard and motive power depot at Feltham. The purchase of of land was confirmed in 1911, with additional land being purchased in 1915. This location gave excellent access t ...

Eastleigh Railway Works
Eastleigh Works is a locomotive, carriage and wagon building and repair facility in the town of Eastleigh, in the county of Hampshire in England. History LSWR The London and South Western Railway (LSWR) opened a carriage and wagon works at Eastleigh in 1891. In 1903, the Chief Mechanical Engineer, Dugald Drummond, oversaw the construction of a large motive power depot in the town; replacing the existing maintenance and repair shops at Northam, Southampton. In January 1910, locomotive building was likewise transferred to the new workshops at Eastleigh from Nine Elms in London. Among the locomotives produced by the LSWR under Drummond at Eastleigh, were the S14 0-4-0 and M7 0-4-4 tank engines, the P14 and T14 4-6-0, and D15 4-4-0, classes. Following the appointment of Robert Urie as Chief Mechanical Engineer in 1912, the works were responsible for the construction of the H15, S15, and N15 (King Arthur) 4-6-0 classes, and the G16 4-8-0, and H16 4-6-0 tank engines.

Continuous Brakes
A railway brake is a type of brake used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them immobile when parked. While the basic principle is similar to that on road vehicle usage, operational features are more complex because of the need to control multiple linked carriages and to be effective on vehicles left without a prime mover. Clasp brakes are one type of brakes historically used on trains. Early days In the earliest days of railways, braking technology was primitive. The first trains had brakes operative on the locomotive tender and on vehicles in the train, where "porters" or, in the United States brakemen, travelling for the purpose on those vehicles operated the brakes. Some railways fitted a special deep-noted brake whistle to locomotives to indicate to the porters the necessity to apply the brakes. All the brakes at this stage of development were applied by operation of a screw and linkage to brake blocks applie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pony Truck
A Bissell or Bissel truck (also Bissel bogie or Pony truck) is a single-axle bogie which pivots towards the centre of a steam locomotive to enable it to negotiate curves more easily. Invented in 1857 by and usually then known as a ''pony truck'', it is a very simple and common means of designing a carrying wheel. Name variants A pony truck in railway terminology, is a leading truck with only two wheels. Its invention is generally credited to Bissell, who devised one in 1857 and patented it the following year. Hence the term ''Bissel bogie'', ''Bissel truck'', or ''Bissel axle'' is used in continental Europe. In the UK, the term is Bissell truck.''Spellings" Conservative locomotive builders in Bissell's native |
Cartazzi Axle
A Cartazzi axle is a design of leading or trailing wheel support used worldwide. The design was used extensively on the former LNER's Pacific steam locomotives and named after its inventor F.J. Cartazzi, formerly of the Great Northern Railway. It should not be confused with a pony truck as it does not pivot at all. The axle does, however, have sideways play built in to accommodate tight curves. Cartazzi's design causes the weight of the locomotive to exert a self-centring action on the trailing wheels. The Cartazzi design was also sometimes applied to driving wheel On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled ... axles on longer wheelbase locomotives. Modelling On small scale models the trailing wheels of Cartazzi-axled locomotives are often flangeless to allow negotiation ...

Sevenoaks Railway Accident
The Sevenoaks railway accident occurred on 24 August 1927 between Dunton Green railway station and Sevenoaks railway station. The Southern Railway's afternoon express from Cannon Street to Deal left London at 5 pm, hauled by River Class tank engine No 800 ''River Cray''. Several passengers later recounted that from time to time the train seemed to roll excessively on fast curves. As it passed through Pollhill Tunnel at 60 mph the rocking became violent and the train derailed past Dunton Green railway station, where the line is in a cutting which is spanned by a bridge carrying Shoreham Lane. The cab of the locomotive struck the bridge and the engine was turned on its side across the cutting. The leading coaches piled up against it, killing 13 and injuring many more. Railway engineer Brigadier-General Archibald Jack was a survivor of the crash. John Wallace Pringle, Chief Inspecting Officer of Her Majesty's Railway Inspectorate conducted the inquiry in person.

Walschaerts Valve Gear
The Walschaerts valve gear is a type of valve gear used to regulate the flow of steam to the pistons in steam locomotives, invented by Belgium, Belgian railway mechanical engineering, engineer Egide Walschaerts in 1844. The gear is sometimes named without the final "s", since it was incorrectly patented under that name. It was extensively used in steam locomotives from the late 19th century until the end of the steam era. History The Walschaerts valve gear was slow to gain popularity. The Stephenson valve gear remained the most commonly used valve gear on 19th-century locomotives. However, the Walschaerts valve gear had the advantage that it could be mounted entirely on the outside of the locomotives, leaving the space between the locomotive frame, frames clear and allowing easy access for service and adjustment, which resulted in it being adopted in some articulated locomotives. The first locomotive fitted with the Walschaerts valve gear was built at the Belgian Tubize worksh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SECR K And SR K1 Classes
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.Scott-Morgan (2002), p. 18 The K class was designed to be mechanically similar to the SECR N class 2-6-0 mixed-traffic locomotives. The class was one of the earliest to use the 2-6-4 wheel arrangement in Britain.Casserley (1966), p. 436 Production began t ...

SR Z Class
The SR Z class was an 0-8-0T 3-cylinder tank engine designed by Richard Maunsell and intended for heavy shunting on the Southern Railway, the first eight entering into service in 1929. It was a successful design and would have been built in greater numbers, but an order for a further ten was cancelled in 1930 due to the reduction in freight traffic as a result of the Great Depression. Background The newly amalgamated Southern Railway needed a group of powerful shunting tank locomotives to work in its marshalling yards around London and on freight transfers between them. Robert Urie's G16 class 4-8-0 performed this task well, and further examples were on order in 1922, but Richard Maunsell considered the firebox to be too large and the superheater an unnecessary expense on such locomotives. He therefore cancelled the order in favour of a new design. Due to the requirement for heavy shunting, the design was provided with an 0-8-0 wheel arrangement to increase traction, whil ...

Tank Locomotive
A tank locomotive or tank engine is a steam locomotive that carries its water in one or more on-board water tanks, instead of a more traditional tender. Most tank engines also have bunkers (or fuel tanks) to hold fuel; in a tender-tank locomotive a tender holds some or all of the fuel, and may hold some water also. There are several different types of tank locomotive, distinguished by the position and style of the water tanks and fuel bunkers. The most common type has tanks mounted either side of the boiler. This type originated about 1840 and quickly became popular for industrial tasks, and later for shunting and shorter-distance main line duties. Tank locomotives have advantages and disadvantages compared to traditional locomotives that required a separate tender to carry needed water and fuel. History Origins The first tank locomotive was the ''Novelty'' that ran at the Rainhill Trials in 1829. It was an example of a ''Well Tank''. However, the more common fo ...

Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of inc ...
