Loading Gauge
A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. Classification systems vary between different countries, and gauges may vary across a network, even if the track gauge is uniform. The term loading gauge can also be applied to the maximum size of road vehicles in relation to tunnels, overpasses and bridges, and doors into automobile repair shops, bus garages, filling stations, residential garages, multi-storey car parks and warehouses. A related but separate gauge is the structure gauge, which sets limits to the extent that bridges, tunnels and other infrastructure can encroach on rail vehicles. The difference between these two gauges is called the clearance. The specified amount of clearance makes allowance for wobbling of ...

Elizabeth II
Elizabeth II (Elizabeth Alexandra Mary; 21 April 1926 – 8 September 2022) was Queen of the United Kingdom and other Commonwealth realms from 6 February 1952 until her death in 2022. She was queen regnant of 32 sovereign states during her lifetime, and was head of state of 15 realms at the time of her death. Her reign of 70 years and 214 days was the longest of any British monarch and the longest verified reign of any female monarch in history. Elizabeth was born in Mayfair, London, as the first child of the Duke and Duchess of York (later King George VI and Queen Elizabeth The Queen Mother). Her father acceded to the throne in 1936 upon the abdication of his brother Edward VIII, making the ten-year-old Princess Elizabeth the heir presumptive. She was educated privately at home and began to undertake public duties during the Second World War, serving in the Auxiliary Territorial Service. In November 1947, she married Philip Mountbatten, a former prince ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eurotunnel Calais Terminal
The Eurotunnel Calais Terminal (also known as the Charles Dickens Terminal or Coquelles Terminal) is a railway terminal built for the transport of road-going vehicles on specially constructed trains through the Channel Tunnel. The terminal is one of two, with the Eurotunnel Folkestone Terminal located at Cheriton, near Folkestone. History As part of the Channel Tunnel project, the plan for services included the use of dedicated shuttle trains that would carry both passenger and freight vehicles between Britain and France, which would compete with the cross-channel ferries. In order to accommodate these services, it was planned to build a brand new vehicle terminal on each side of the tunnel that would allow cars and lorries to be loaded quickly onto the trains. The site chosen for the French terminal was Coquelles, near Calais, not far from the French tunnel portal. The site chosen was a large greenfield area of more than 1700 acres, which provided significantly more s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velim Railway Test Circuit
The Velim test center ( cs, Zkušební centrum Velim) is a railway rolling stock testing facility at Cerhenice, close to the town of Kolín in the Central Bohemian Region of the Czech Republic. Perhaps its most notable feature is the Velim railway test circuit ('), which consists of two large standard gauge railway track ovals, designed to allow the continuous running of rail vehicles for evaluation and testing. The Velim test centre was constructed during the 1960s and was largely used for domestic purposes early on. During the 1990s, it became increasing popular with international customers, which drove demands to recondition the center's facilities to fulfill the latest standards of the rail industry. Between 2005 and 2014, an extensive modernisation programme was undertaken at Velim; this involved most aspects of its operations, including power supplies, signalling, overhead electrification, preparation halls, and track. The Velim test center is presently owned by the ''Railway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission Voie-Machine
Transmission Voie-Machine (TVM, English: track-to-train transmission) is a form of in-cab signalling originally deployed in France and is mainly used on high-speed railway lines. TVM-300 was the first version, followed by TVM-430. TVM-300 was developed in the 1970s as part of the TGV project. At speeds faster than 220 kilometres per hour, TGV trains only run along dedicated tracks designated as (LGV). When travelling at high speed, it is not possible for the driver to accurately see colour-light railway signals at the side of the track. Signalling information is instead transmitted to the train and displayed on the train driver's dashboard. The driver is shown the safe operating speed, measured in kilometres per hour. The 1980s-developed TVM-430 system provides more information than traditional signalling systems would allow, including track gradient profiles and information about the state of signalling blocks further ahead. This high degree of automation does not remove the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rectifier
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The reverse operation (converting DC to AC) is performed by an Power inverter, inverter. The process is known as ''rectification'', since it "straightens" the direction of current. Physically, rectifiers take a number of forms, including Vacuum tube#Diodes, vacuum tube diodes, wet chemical cells, mercury-arc valves, stacks of copper and selenium rectifier, selenium oxide plates, Diode#Semiconductor diodes, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches. Historically, even synchronous electromechanical switches and motor-generator sets have been used. Early radio receivers, called crystal radios, used a "Cat's-whisker detector, cat's whisker" of fine wire pressing on a crystal of galena (lead sulfide) to serve as a point-contact rectifier or "crystal detec ...

New Zealand Railways Corporation
New Zealand Railways Corporation (NZRC) is the state-owned enterprise that owns the land beneath KiwiRail's Rail transport in New Zealand, railway network on behalf of the Crown. The Corporation has existed under a number of guises since 1982, when the old New Zealand Railways Department was corporatised followed by deregulation of the land transport sector. In 1986, the Corporation became a State-owned enterprise, required to make a profit. Huge job losses and cutbacks ensued, and the rail network, rail operations and ferry service of the Corporation were transferred to Tranz Rail, New Zealand Rail Limited in 1990. The Corporation retained ownership of the land beneath the railway network, and charged a nominal rental to New Zealand Rail, which was privatised in 1993, and renamed Tranz Rail in 1995. In 2004, following a deal with Tranz Rail's new owners Toll NZ, the Corporation took over responsibility for maintaining and upgrading the rail network once more, trading under the nam ...

New Zealand EF Class Locomotive
The New Zealand EF class locomotive (originally Class 30) is a class of electric locomotives that operate on the North Island Main Trunk (NIMT) between Palmerston North and Te Rapa in New Zealand. Built by Brush Traction in Loughborough, England between 1986 and 1988 to run on the new electrified central section of the NIMT, at , they are the most powerful locomotives to operate in New Zealand. They are the only class of electric locomotives currently in service in New Zealand. Background The NIMT is a long rail line that links New Zealand's capital Wellington and largest city Auckland, and is one of the major backbones of the country's rail network. The line was completed in 1908 and opened the following year, and included various engineering feats on the central section between Hamilton and Palmerston North, including the Raurimu Spiral and numerous viaducts – five of which are over high. Electrification of the NIMT was first proposed as early as 1918 due to coal shor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narrow Gauge Railway
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard; Japan, Indonesia, Taiwan, New Zealand, South Africa, and the Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
