T Gauge
T gauge (1:450 or 1:480) is a model railway scale with a track gauge of , referred from "Three-millimeter gauge" or "Third of N scale". It was introduced at the Tokyo Toy Show in 2006 by KK Eishindo of Japan, and went on sale in 2007. It is the smallest commercial model train scale in the world (with ZZ scale being second smallest). Since mid-2009, Railway Shop (Hong Kong) is the exclusive licensed manufacturer. The models are powered with a battery-powered throttle (with optional AC adapter) at a maximum output of 4.5 V DC. To improve power pickup and tractive effort, the powered cars are fitted with magnetic wheels, and the track has steel rails. The first train released is the Japanese 103 series commuter train in different versions. Each standard trainset comes with two powered cars, which are located in the centre of the train. The front and rear cars are equipped with directional headlights. The tiny pantographs are made of etched stainless steel. The Hankyu Railway ...

TT Scale
TT scale is a model railroading scale, whose name stands for ''table top''. Its 1:120 scale (from a common engineering scale where one inch equals ten feet) and gauge are roughly halfway between HO scale (1:87) and N scale (1:160). Its original purpose, like the name suggests, was to make a train set small enough to assemble and operate on a tabletop. The scale originated in the USA, but is today widespread mainly in Central Europe, thanks to "Berliner Bahnen", a defunct East German manufacturer of train sets in TT. It is the second-most popular scale in Central Europe and Russia, after HO, and adherents to TT maintain it is the smallest practical scale, especially for those who like to build models from scratch. In other parts of the world it is less spread, and can be described as a niche scale in the United States and the United Kingdom. In wargaming, the TT scale equals the 15 mm scale where the height of "standard" soldier height is . For British 3mm-scale, see 3 m ...

Magnet
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to ...

Model Airports
A model airport is a scale model of an airport. While airport models have been around, in a way, since airfields were open to the public, early model airports were basically restricted to public showcases about the airport and its surroundings to the public; these were usually located inside the airport themselves. Since Herpa Wings's introduction of their ''airport set'' series to their line of airline related toys, there has been an increase of aircraft modelers who have made mock airports to showcase their private collection of model aircraft. Often, the collector will model their airport after a real-life airport. Model airports can be made to look very realistic, with many real airport features such as terminals, control towers, cargo terminals, hangars, passenger bridges and more, Gemini Jets, Herpa Wings, and JC Wings have produced ground support equipment in various scales. Collectors who make model airports may use die-cast models for their creation. Among the brands o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model Airplanes
A model aircraft is a small unmanned aircraft. Many are replicas of real aircraft. Model aircraft are divided into two basic groups: flying and non-flying. Non-flying models are also termed static, display, or shelf models. Aircraft manufacturers and researchers make wind tunnel models for testing aerodynamic properties, for basic research, or for the development of new designs. Sometimes only part of the aircraft is modelled. Static models range from mass-produced toys in white metal or plastic to highly accurate and detailed models produced for museum display and requiring thousands of hours of work. Many are available in kits, typically made of injection-moulded polystyrene or resin. Flying models range from simple toy gliders made of sheets of paper, balsa, card stock or foam polystyrene to powered scale models built up from balsa, bamboo sticks, plastic, (including both moulded or sheet polystyrene, and styrofoam), metal, synthetic resin, either alone or with carbon f ...

Overhead Lines
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...

103 Series
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D VI TGauge
D, or d, is the fourth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''dee'' (pronounced ), plural ''dees''. History The Semitic letter Dāleth may have developed from the logogram for a fish or a door. There are many different Egyptian hieroglyphs that might have inspired this. In Semitic, Ancient Greek and Latin, the letter represented ; in the Etruscan alphabet the letter was archaic, but still retained (see letter B). The equivalent Greek letter is Delta, Δ. Architecture The minuscule (lower-case) form of 'd' consists of a lower-story left bowl and a stem ascender. It most likely developed by gradual variations on the majuscule (capital) form 'D', and today now composed as a stem with a full lobe to the right. In handwriting, it was common to start the arc to the left of the vertical stroke, resulting in a serif at the top of the arc. This seri ...

Rail Transport Modelling
Railway modelling (UK, Australia, New Zealand, and Ireland) or model railroading (US and Canada) is a hobby in which rail transport systems are modelled at a reduced Scale (ratio), scale. The scale models include locomotives, rolling stock, streetcars, rail tracks, tracks, Railway signal, signalling, Crane (machine), cranes, and landscapes including: countryside, roads, bridges, buildings, vehicles, harbors, urban landscape, model figures, lights, and features such as rivers, hills, tunnels, and canyons. The earliest model railways were the 'carpet railways' in the 1840s. The first documented model railway was the Railway of the Prince Imperial (French: Chemin de fer du Prince impérial) built in 1859 by emperor Napoleon III for his then 3-year-old son, also Napoleon, in the grounds of the Château de Saint-Cloud in Paris. It was powered by clockwork and ran in a figure-of-eight. Electric trains appeared around the start of the 20th century, but these were crude likenesses. M ...
