Holcroft Valve Gear
The Holcroft valve gear was a type of conjugated valve gear designed and patented by Harold Holcroft and used on three-cylinder steam locomotives of the South Eastern & Chatham Railway (SECR). It bore many similarities to the Gresley conjugated valve gear, which it predated, as eventually used on all Gresley's three cylinder designs. It varied from the Gresley method of operation by using the combination lever assembly instead of the valve spindles to drive the middle cylinder of a three-cylinder design. This had operational advantages over Gresley's design, namely eliminating the problems of flexure, bush wear and the influence of heat in the valve spindles. Background Whilst working for the Great Western Railway at Swindon Works, Holcroft schemed out and patented (in 1909) a conjugated valve gear for three-cylinder steam locomotives, which allowed for the elimination of the valve gear for the inside cylinder by deriving the motion for the inside valve from that of the outside val ...

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.Scott-Morgan (2002), p. 18 The N1 prototype was the result of modifications made to N class No. 822 during construction in 1922. The locomotive became operational in 1923 and used parts interchangeable with other Maunsell locomotive classes. The prototype N1 was the only member of the class constructed before the SECR became part of the Southern Railway at the Grouping in 1923, and featured Holcroft conjugated valve gear, Holcroft's experience in this field later aided in the development of the Gresley conjugated valve gear which ...

Ian Allan Publishing
Ian Allan Publishing was an English publisher, established in 1942, which specialised in transport books. It was founded by Ian Allan. In 1942 Ian Allan, then working in the public relations department for the Southern Railway at Waterloo station, decided he could deal with many of the requests he received about rolling stock by collecting the information into a book. The result was his first book, ''ABC of Southern Locomotives''. This proved to be a success, contributing to the emergence of trainspotting as a popular hobby in the UK, and leading to the formation of the company.Ian Allan…the man who launched a million locospotters ''The Railway Magazine'' issue 1174 February 1999 pages 20-27 The company grew from a small producer of books for train enthusiasts and spotters to a large transport publisher. Each year it published books covering subjects such as military and civil aviation, naval and maritime topics, buses, trams, trolleybuses and steam railways, including hi ...

Model Engineer
''Model Engineer Magazine'' was first published (in the United Kingdom) to support the hobby of model engineering in 1898 by Percival Marshall, who was to remain its editor for over 50 years. It has been owned by MyTime Media since 2008. The magazine addressed the emergence of a new hobby — the construction of models (often working) and experimental engineering, largely in metal. It transcended class barriers, appealing to professional engineers, jobbing machinists and anyone interested in making working mechanisms. Contributors The magazine has had many notable contributors, but foremost among these was LBSC ( pen name of Lillian 'Curly' Lawrence). From the inter-war period to the 1960s he produced many designs for simple but reliable small model steam locomotives. Most of these were published in ''Model Engineer'', and brought the construction of small passenger hauling locomotives within the reach of the typical home machinist. Other notable contributors include Henry Green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baker Valve Gear
After about 1910, the Baker valve gear was the main competitor to Walschaerts valve gear for steam locomotives in the United States. Strictly speaking it was not a valve gear but a variable expansion mechanism adapted to the Walschaerts layout replacing the expansion link and sliding die block. The Baker arrangement used more pivot bearings or ''pin joints'', but avoided the die slip inherent to the expansion link, with the aim of lessening wear and the need for service; it could also facilitate longer valve travel. History In the early 1900s there were many efforts to create a new valve gear to replace the by-then-standard Walschaerts valve gear. In the United States the Young, Southern, Caprotti and Franklin patterns were used on a few classes, but only the Baker pattern won more than limited acceptance. The design originated in the A.D. Baker Company, of Swanton, Ohio; a builder of steam traction engines. The idea came from an employee called Gifford but was developed by ...

Tugboat Annie
''Tugboat Annie'' is a 1933 American pre-Code film directed by Mervyn LeRoy, written by Norman Reilly Raine and Zelda Sears, and starring Marie Dressler and Wallace Beery as a comically quarrelsome middle-aged couple who operate a tugboat. Dressler and Beery were MGM's most popular screen team at that time, having recently made the bittersweet ''Min and Bill'' (1930) together, for which Dressler won the Academy Award for Best Actress. The boisterous Tugboat Annie character first appeared in a series of stories in the ''Saturday Evening Post'' written by the author Norman Reilly Raine which were supposedly based on the life of Thea Foss of Tacoma, Washington. There is also a theory that her character is loosely based on Kate A. Sutton, secretary and dispatcher for the Providence Steamboat Company during the 1920s. ''Tugboat Annie'' also features Robert Young and Maureen O'Sullivan as the requisite pair of young lovers. Captain Clarence Howden piloted Annie's tugboat "''Narcissus ...

Live Steam
Live steam is steam under pressure, obtained by heating water in a boiler. The steam is used to operate stationary or moving equipment. A live steam machine or device is one powered by steam, but the term is usually reserved for those that are replicas, scale models, toys, or otherwise used for heritage, museum, entertainment, or recreational purposes, to distinguish them from similar devices powered by electricity, internal combustion, or some other more convenient method but designed to look as if they are steam-powered. Revenue-earning steam-powered machines such as mainline and narrow gauge steam locomotives, full-sized steamships, and the worldwide electric power-generating industry steam turbines are not normally referred to as "live steam". Steamrollers and traction engines are popular, in 1:4 or 1:3 scale, as are model stationary steam engines, ranging from pocket-size to 1:2 scale. Railroads or railways Ridable, large-scale live steam railroading on a backyard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curly Lawrence
Lillian "Curly" Lawrence (September 27, 1883 – November 4, 1967), known as LBSC, was one of Britain's most prolific and well known model or scale-steam-locomotive designers. LBSC were the initials of Britain's London, Brighton and South Coast Railway, where he was once employed as a fireman. Early life LBSC, "Curly" to his friends, was born 27 September 1883 and christened William Morris Benjamin, later changing his surname to Mathieson when his father changed the family name. After 1902, he changed his name to Lillian Lawrence; why he chose a female name is unclear, however he was nicknamed "Dolly" at school by account of his long, blond, curly hair, and was pictured on occasion, wearing female shoes and clothing while driving his models. Despite his 'unusual make-up', as described by his friend George Barlow, his retiring nature, and the prejudices that may have existed in 1930s, he was readily accepted as an expert live steam model engineer. Lawrence had been making stea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotive Frame
A locomotive frame is the structure that forms the backbone of the railway locomotive, giving it strength and supporting the superstructure elements such as a cab, boiler or bodywork. The vast majority of locomotives have had a frame structure of some kind. The frame may in turn be supported by axles directly attached to it, or it may be mounted on bogies ( UK) / trucks ( US), or a combination of the two. The bogies in turn will have frames of their own. Types of frame 250px, Preserved GWR 9017 showing outside frames Three main types of frame on steam locomotives may be distinguished:, p 255. Plate frames These used steel plates about thick. They were mainly used in Britain and continental Europe. On most locomotives, the frames would be situated within the driving wheels ("inside frames"), but some classes of an early steam locomotive and diesel shunters were constructed with "outside frames". Some early designs were double framed where the frame consisted of plates both in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Railway (England)
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 and South Western Railway (LSWR), the London, Brighton and South Coast Railway (LB&SCR) and the South Eastern and Chatham Railway (SE&CR).Bonavia (1987) pp. 26-28 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. The railway was noted for its astute use of public relations and a coherent management structure headed by Sir Herbert Walker. At , the Southern Railway was the smallest of the '' Big Four'' railway companies and, unlike the others, the majority of its revenue came from passenger traffic rather than freight. ...

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 ...
