Vacuum Brake
The vacuum brake is a brake, braking system employed on trains and introduced in the mid-1860s. A variant, the automatic vacuum brake system, became almost universal in British train equipment and in countries influenced by British practice. Vacuum brakes also enjoyed a brief period of adoption in the United States, primarily on narrow-gauge railroads. Their limitations caused them to be progressively superseded by Railway air brake, compressed air systems starting in the United Kingdom from the 1970s onward. The vacuum brake system is now obsolete; it is not in large-scale usage anywhere in the world, other than in South Africa, largely supplanted by railway air brake, air brakes. Introduction In the earliest days of railways, trains were slowed or stopped by the application of manually applied brakes on the locomotive and in brake vehicles through the train, and later by steam power brakes on locomotives. This was clearly unsatisfactory, given the slow and unreliable response ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
British Rail Class 46
The British Rail Class 46 is a class of diesel locomotive. They were built from 1961 to 1963 at British Railways' Derby Works and were initially numbered D138–D193. With the arrival of TOPS they were renumbered to Class 46. Along with the similar British Rail Class 44, Class 44 and British Rail Class 45, 45 locomotives, they became known as ''Peaks''. Fifty-six locomotives were built. The first was withdrawn in 1977 and all were withdrawn by the end of 1984. Overview The Class 46 design was structurally the same as the preceding British Rail Class 45, Class 45 build, and had the same Sulzer (manufacturer), Sulzer engine, but differed in the fitment of a Brush Traction, Brush generator and traction motors, in place of the Crompton Parkinson equipment fitted to the Class 45. Along with the other Sulzer class 44 and 45 designs they are often referred to as "Peaks", so named because the Class 44s were named after mountains.

Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover (locomotive), power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel–electric locomotives and diesel–hydraulic. Early internal combustion engine, internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low-power gasoline engines could be coupled to mechanical transmission (mechanics), transmissions, the more powerful diesel engines required the development of new forms of transmiss ...

British Railways
British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most rail transport in Great Britain from 1948 to 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in January 1963, when it was formally renamed the British Railways Board. British Railways was formed on 1 January 1948 as a result of the Transport Act 1947, which nationalisation, nationalised the Big Four (British railway companies), Big Four British railway companies along with some other (but not all) smaller railways. Profitability of the railways became a pressing concern during the 1950s, leading to multiple efforts to bolster performance, including some line closures. The History of rail transport in Great Britain 1948–1994#The Modernisation Plan, 1955 Modernisation Plan formally directed a process of dieselisation and Railway electrification in Great Britain, electrification ...

Railway Air Brake
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, referred to as a ''straight air system'', compressed air is directed to a ''brake cylinder'', causing its piston to apply force to mechanical linkage, which linkage is conventionally referred to as the ''brake rigging'' (see illu ...

Rheinmetall Air Defence
Rheinmetall Air Defence AG is a division of German armament manufacturer Rheinmetall, created when the company's Oerlikon Contraves unit was renamed on 1 January 2009 and integrated with Rheinmetall's other air-defence products. Oerlikon Contraves was a Swiss anti-aircraft artillery manufacturer famous for its adaptation of the 1916 20 mm Becker as the Oerlikon 20 mm autocannon design, which was used in the Second World War and remains in use. Copies and derivatives of these designs were made by German, French, British, and Japanese weapon manufacturers. Oerlikon Contraves was purchased by Rheinmetall in 1999. , Rheinmetall Air Defence had around 1,050 employees at locations in Switzerland, Germany, Italy, and Canada. The group's sales were about . History Oerlikon's earliest predecessor was Schweizerische Werkzeugmaschinenfabrik Oerlikon, founded in the Oerlikon district of Zürich, Switzerland in 1906. In 1923 it acquired a factory in Germany.

Moel Tryfan (locomotive)
''Moel Tryfan'' was a narrow gauge steam locomotive built for use on the North Wales Narrow Gauge Railways (NWNGRs) in 1874/5. The locomotive was an single Fairlie locomotive built by the Vulcan Foundry near Manchester. It spent its entire working life on the NWNGRs and its successors the Welsh Highland Railway (WHR) and the Ffestiniog Railway (FfR). History North Wales Narrow Gauge Railways The North Wales Narrow Gauge Railways built two gauge railways, connecting , near Caernarfon, with , and . Two identical locomotives were ordered from the Vulcan Foundry to work the new railway. They were built to Fairlie's patent for articulated locomotives and were designed by George Percival Spooner, son of Charles Eaton Spooner, the manager of the nearby FfR. The locomotives were the first s in the British Isles. They were named ''Moel Tryfan'' and ''Snowdon Ranger''.

North Wales Narrow Gauge Railway
The North Wales Narrow Gauge Railways (NWNGR) was a railway company that planned to build a number of inter-connected narrow-gauge railways across North Wales. The first two of these lines – jointly known as the "Moel Tryfan Undertaking" – were authorised by act of Parliament, the (35 & 36 Vict. c. clxxv) and were built and opened in the 1870s. The original main line ran from Dinas railway station, Dinas Junction to Bryngwyn Station, Bryngwyn and opened in 1877. The second line was a branch from Tryfan Junction to Rhyd Ddu railway station, South Snowdon, though shortly after opening, the company designated the Tryfan Junction to Bryngwyn section as the branch, and the Dinas Junction to South Snowdon section as the main line. Routes built The company completed construction of two lines, The first, opened in 1877, was approximately long, running south-east from a junction with the London and North Western Railway's Carnarvonshire Railway, Caernarfon to Afon Wen branch at ...

Vale Of Rheidol Railway
The Vale of Rheidol Railway () is a Narrow gauge railway, narrow gauge heritage railway in Ceredigion, Wales, between Aberystwyth and Devil's Bridge, Ceredigion, Devil's Bridge; a journey of . It opened in 1902 and, from the Withdrawal of steam on British Rail, withdrawal of main line steam on British Rail in 1968 until privatisation in 1989, it was the sole steam-operated line on the Transport Act 1947, 1948 nationalised British Rail network. It was one of the first parts of British Rail to be privatised. Unlike most other preserved railways in the United Kingdom, the Vale of Rheidol Railway did not have a period of closure between its being part of the national rail system and becoming a heritage railway, and so has operated a continuous service for residents and tourists.

List Of Vale Of Rheidol Railway Rolling Stock
This is a list of past and present rolling stock used on the Vale of Rheidol Railway (), a Narrow gauge railway, narrow gauge heritage railway, opened in 1902, that runs for between Aberystwyth and Devil's Bridge, Ceredigion, Devil's Bridge in the county of Ceredigion, Wales. The railway was later operated by the Cambrian Railways, Great Western Railway and British Rail before being 'privatised' in 1989 and run as a heritage railway operation (though arguably it had operated as a tourist railway operation since the mid-1930s, when the GWR withdrew freight services and winter passenger services, rendering the railway wholly reliant on the tourist trade). When first opened, the railway owned two steam locomotives, No 1 ''Edward VII'' and No 2 ''Prince of Wales'', along with a third contractor's locomotive No 3 Rheidol. In 1922 the Great Western Railway took over the running of the line and over the next two decades invested heavily in new locomotives and replacement rolling sto ...
