H0 Scale
HO or H0 is a rail transport modelling scale using a 1:87 scale (3.5 mm to 1 foot). It is the most popular scale of model railway in the world. The rails are spaced apart for modelling standard gauge tracks and trains in HO. The name HO comes from 1:87 scale being ''half'' that of O scale, which was originally the smallest of the series of older and larger 0, 1, 2 and 3 gauges introduced by Märklin around 1900. Rather than referring to the scale as "half-zero" or "H-zero", English-speakers have consistently pronounced it and have generally written it with the letters HO. In other languages it also remains written with the letter H and number 0 (zero); in German it is thus pronounced as . In Japan, many models are produced using 1:80 scale proportions (16.5mm track is still used). History After the First World War there were several attempts to introduce a model railway about half the size of 0 scale that would be more suitable for smaller home layouts and ...

Switcher Locomotive
A switcher locomotive (American English), shunter locomotive (British English), station pilot (British English), or shifter locomotive (Pennsylvania Railroad terminology) is a locomotive used for maneuvering railway vehicles over short distances. Switchers do not usually move train A train (from Old French , from Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... , from Latin , "to pull, to draw") is a series of connected vehicles th ...s over long distances. Instead, they typically assemble trains in order for another locomotive to take over. Switchers often operate in a railyard or make short transfer runs. They may serve as the primary motive power on short branch lines or switching and terminal railroads. A hybrid type known as a road switcher can both shunt and haul trains. Switchers are optimized for their role, being relatively low-powered but with a high starting tractive eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
View Of A
Acornsoft was the software arm of Acorn Computers, and a major publisher of software for the BBC Micro and Acorn Electron. As well as games, it also produced a large number of educational titles, extra computer languages and business and utility packages – these included word processor ''VIEW'' and the spreadsheet '' ViewSheet'' supplied on ROM and cartridge for the BBC Micro/Acorn Electron and included as standard in the BBC Master and Acorn Business Computer. History Acornsoft was formed in late 1980 by Acorn Computers directors Hermann Hauser and Chris Curry, and David Johnson-Davies, author of the first game for a UK personal computer and of the official Acorn Atom manual "Atomic Theory and Practice". David Johnson-Davies was managing director and in early 1981 was joined by Tim Dobson, Programmer and Chris Jordan, Publications Editor. While some of their games were clones or remakes of popular arcade games (e.g. ''Hopper'' is a clone of Sega's ''Frogger'', '' Snapper ...

MOROP
MOROP is a European association that federates national associations of railroad and model railroad enthusiasts. MOROP was founded in Genoa, Italy by Italo Briano in 1954, and now has its headquarters in Bern, Switzerland. In 2006, MOROP federated 22 national associations from 17 European countries, with a total of more than 30,000 members. The term "MOROP" is a portmanteau derived from "''MOdellbahn''" (German for "model railway") and EuROPe. The most important activity of MOROP is to define and maintain the '' Normen Europäischer Modellbahnen'' (NEM) ("European Standards for Railway Modelling") standards for model railroads. Since 1994, close ties have been established with the National Model Railroad Association (NMRA) which defines model railroad standards for the United States The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic of 50 U.S. state, states and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
OO Scale
OO gauge or OO scale (also, 00 gauge and 00 scale) is the most popular standard gauge model railway standard in the United Kingdom, outside of which it is virtually unknown. OO gauge is one of several 4 mm-scale standards (4 mm to , or 1:76.2), and the only one to be marketed by major manufacturers. The OO track gauge of (same as the 1:87 HO scale) corresponds to prototypical gauge of , rather than standard gauge. However, since the 1960s, other gauges in the same scale have arisen – 18.2 mm ( EM) and 18.83 mm ( Scalefour) — to reflect the desire of some modellers for greater scale accuracy. Origin Double-0 scale model railways were launched by Bing in 1921 as "The Table Railway", running on track and scaled at 4 mm to the foot. In 1922, the first models of British prototypes appeared. Initially all locomotives were powered by clockwork, but the first electric power appeared in 1923. "OO" describes models with a scale of 4 mm = 1 foot (1:76) ...

N&W Model @ Crewe
The Norfolk and Western Railway , commonly called the N&W, was a US class I railroad, formed by more than 200 railroad mergers between 1838 and 1982. It was headquartered in Roanoke, Virginia, for most of its existence. Its motto was "Precision Transportation"; it had a variety of nicknames, including "King Coal" and "British Railway of America". In 1986, N&W merged with Southern Railway (U.S.), Southern Railway to form today's Norfolk Southern Railway. The N&W was famous for manufacturing its own steam locomotives, which were built at the Roanoke Shops, as well as its own hopper cars. After 1960, N&W was the last major Class I railroad using steam locomotives; the last remaining Y class 2-8-8-2s would eventually be retired in 1961. In December 1959, the N&W merged with the Virginian Railway (reporting mark VGN), a longtime rival in the Pocahontas coal region. By 1970, other mergers with the New York, Chicago & St. Louis Railroad, Nickel Plate Road and Wabash Railroad, Wabash ...

Price Point
In economics, a price point is a point along the demand curve at which demand for a given product is supposed to stay relatively high. The term "price point" is often used incorrectly to refer to a price. Characteristics Introductory microeconomics depicts a demand curve as downward-sloping to the right and either linear or gently convex to the origin. The downward slope generally holds, but the model of the curve is only piecewise true, as price surveys indicate that demand for a product is not a linear function of its price and not even a smooth function. Demand curves resemble a series of waves rather than a straight line. The diagram shows price points at the points labeled A, B, and C. When a vendor increases a price beyond a price point (say to a price slightly above ''price point B''), sales volume decreases by an amount more than proportional to the price increase. This decrease in quantity demanded more than offsets the additional revenue from the increased unit p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Rolling Stock
The term rolling stock in the rail transport industry refers to railway vehicles, including both powered and unpowered vehicles: for example, locomotives, Railroad car#Freight cars, freight and Passenger railroad car, passenger cars (or coaches), and Railroad car#Non-revenue cars, non-revenue cars. Passenger vehicles can be un-powered, or self-propelled, Railcar, single or Multiple unit, multiple units. In North America, Australia and other countries, the term consist ( ) is used to refer to the rolling stock comprising a train, a list containing specific information for each car of a train, or a group of locomotives. In the United States, the term ''rolling stock'' has been expanded from the older broadly defined "trains" to include wheeled vehicles used by businesses on roadways. The word ''stock'' in the term is used in a sense of inventory. Rolling stock is considered to be a liquid asset, or close to it, since the value of the vehicle can be readily estimated and then ship ...

Locomotive
A locomotive is a rail transport, rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, Push–pull train, push–pull operation has become common, and in the pursuit for longer and heavier freight trains, companies are increasingly using distributed power: single or multiple locomotives placed at the front and rear and at intermediate points throughout the train under the control of the leading locomotive. Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first used in 1814 to distinguish between self-propelled and stationary steam engines. Classifications Prior to locomotives, the motive force for railways had been generated by various lower-technology methods such as human power, horse power, Gravity railroad, g ...

Great Depression
The Great Depression was a severe global economic downturn from 1929 to 1939. The period was characterized by high rates of unemployment and poverty, drastic reductions in industrial production and international trade, and widespread bank and business failures around the world. The economic contagion began in 1929 in the United States, the largest economy in the world, with the devastating Wall Street stock market crash of October 1929 often considered the beginning of the Depression. Among the countries with the most unemployed were the U.S., the United Kingdom, and Weimar Republic, Germany. The Depression was preceded by a period of industrial growth and social development known as the "Roaring Twenties". Much of the profit generated by the boom was invested in speculation, such as on the stock market, contributing to growing Wealth inequality in the United States, wealth inequality. Banks were subject to laissez-faire, minimal regulation, resulting in loose lending and wides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Track Ballast
Track ballast is the material which forms the trackbed upon which railroad ties (UK: sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the compression load of the railroad ties, rails, and rolling stock; to facilitate drainage; and keep down vegetation that can compromise the integrity of the combined track structure. Ballast also physically holds the track in place as the trains roll over it. Not all types of railway tracks use ballast. A variety of materials have been used as track ballast, including crushed stone, washed gravel, bank run (unwashed) gravel, torpedo gravel (a mixture of coarse sand and small gravel), slag, chats, coal cinders, sand, and burnt clay. The term "ballast" comes from a nautical term for the stones used to stabilize a ship. Construction The appropriate thickness of a layer of track ballast depends on the size and spacing of the ties, the amount of traffic on the line, and various other factors. Track ballast ...
