Gn15
Gn15 is a rail modelling scale, using G scale 1:22.5 scale trains running on H0/00 gauge () track, representing minimum gauge and miniature railways. Typical models built are between 1:20.3 and 1:24, or up to 1:29. ' NEM 010 specification defines IIp for modelling gauge. History Gn15 modeling is a relatively new phenomenon in the model railroading world. While the idea of this scale has existed for some time, as evidenced by the early efforts of Marc Horovitz, editor of ''Garden Railways'' magazine, Gn15 did not gain any measure of popularity until the Sidelines range of models. Following the advent of these kits, a few other lines of kits became available. Initial community development took place on Yahoo email groups, but these have been superseded by the forums aGn15.infoas the primary form of communication between the far flung practitioners of this scale. 09, GNine and related scales Alongside Gn15 other modeling scales have developed to cover both the modelling of mi ...

Model Railroad Scales
Rail transport modelling uses a variety of scales (ratio between the real world and the model) to ensure scale models look correct when placed next to each other. Model railway scales are standardized worldwide by many organizations and hobbyist groups. Some of the scales are recognized globally, while others are less widespread and, in many cases, virtually unknown outside their circle of origin. Scales may be expressed as a numeric ratio (e.g. 1/87 or 1:87) or as letters defined in rail transport modelling standards (e.g. HO, OO, N, O, G, TT and Z.) The majority of commercial model railway equipment manufacturers base their offerings on ''Normen Europäischer Modellbahnen'' (NEM) or National Model Railroad Association (NMRA) standards in most popular scales. Terminology Although '' scale'' and ''gauge'' are often confused, ''scale'' means the ratio between a unit of measurement on a model compared with a unit of measurement in corresponding full size prototype, while ''g ...

G Scale
Large scale or G scale (, G gauge) is a track gauge for model railways which is often used for outdoor garden railways because of its size and durability. G scale trains use a fixed track gauge of to accommodate a range of rail transport modelling scales between narrow gauge ( ~1:13‒ 1:19‒ 1:20), metre gauge ( 1:22.5), Playmobil trains ( ~1:24), and standard gauge (~1:29– 1:32). G-scale LGB (, "Lehmann's Big Train") was introduced in 1968 by Ernst Paul Lehmann Patentwerk in Germany. LGB products were intended for indoor and outdoor use; so the "G" became interpreted as "garden scale". Most track is made of brass which can remain outside in all weather. Track can also be obtained in less expensive aluminium as well as oxidation-resistant, though more expensive, stainless steel. Like other scales, large scale is sometimes used for model trains that run indoors on a track mounted against the wall near the ceiling. G scale versus G gauge G gauge track has a spacing of ...

HO 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.NMRA"Modeling Scales: Scale and Gauge. ''NMRA.org''. December 2000. Retrieved 4 March 2010. The name H0 comes from 1:87 scale being ''half'' that of 0 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 . 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 chea ...

Minimum Gauge Railway
Minimum-gauge railways have a gauge of most commonly , , , , , or . The notion of minimum-gauge railways was originally developed by estate railways and the French company of Decauville for light railways, trench railways, mining, and farming applications. History The term was originally conceived by Sir Arthur Percival Heywood, who used it in 1874 to describe the principle behind his Duffield Bank Railway, specifically its gauge, distinguishing it from a "narrow gauge" railway. Having previously built a small railway of gauge, he settled on as the minimum that he felt was practical. The original text of Heywood's article defining minimum gauge railways is available online. In general, minimum-gauge railways maximize their loading gauge, where the dimension of the equipment is made as large as possible with respect to the track gauge while still providing enough stability to keep it from tipping over. Standard gauge railways have vehicles that are approximately twice, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rowland Emett
Frederick Rowland Emett OBE (22 October 190613 November 1990), known as Rowland Emett (with the forename sometimes spelled "Roland" s his middle name appears on his birth certificateand the surname frequently misspelled "Emmett"), was an English cartoonist and constructor of whimsical kinetic sculpture. Early life Emett was born in New Southgate, London, the son of a businessman and amateur inventor, and the grandson of Queen Victoria's engraver. He was educated at Waverley Grammar School in Birmingham, where he excelled in drawing, caricaturing his teachers and vehicles and machinery. When he was only 14 he took out a patent on a gramophone volume control. He studied at Birmingham School of Arts and Crafts and one of his landscapes, ''Cornish Harbour'', was exhibited at the Royal Academy; it is now in the Tate collection. Later work An otherwise undistinguished career was interrupted by World War II, when he worked as a draughtsman for the Air Ministry while perfecting h ...

Sir Arthur Heywood
Sir Arthur Percival Heywood, 3rd Baronet (25 December 1849 – 19 April 1916) is best known today as the innovator of the fifteen inch minimum gauge railway, for estate use. Early life He was the eldest son of Sir Thomas Percival Heywood and grew up in the family home of Dove Leys at Denstone in Staffordshire. Dove Leys looked over the valley where the North Staffordshire Railway from Rocester to Ashbourne ran. The family travelled by train to their relatives in Manchester and on holiday to Inveran in the Highland region of Scotland. Heywood developed a passion for the railway from an early age. He assisted his father in his hobby of ornamental metalwork, with a Holtzapffel lathe, and in his late teenage, built a 4 in gauge model railway with a steam locomotive. Wanting something on which his younger siblings could ride, he went on to build a 9 in gauge locomotive and train, which gave him the experience for his later ventures. Initially schooled at Eton, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
N Scale
N scale is a popular model railway scale. Depending upon the manufacturer (or country), the scale ranges from 1:148 to 1:160. In all cases, the ''gauge'' (the distance between the rails) is . The term N ''gauge'' refers to the track dimensions, but in the United Kingdom in particular British N gauge refers to a 1:148 scale with 1:160 () track gauge modelling. The terms N scale and N gauge are often inaccurately used interchangeably, as scale is defined as ratio or proportion of the model, and gauge only as a distance between rails. The scale 1:148 defines the rail-to-rail gauge equal to 9 mm exactly (at the cost of scale exactness), so when calculating the rail or track use 1:160 and for engines and car wheel base use 1:148. All rails are spaced 9 mm apart but the height can differ. Rail height (in thousandths of an inch) is expressed as a "code": thus, Code 55 rails are high while Code 80 rails have a height of . Common real railroad rails are at least tall and can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Email
Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic ( digital) version of, or counterpart to, mail, at a time when "mail" meant only physical mail (hence '' e- + mail''). Email later became a ubiquitous (very widely used) communication medium, to the point that in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. ''Email'' is the medium, and each message sent therewith is also called an ''email.'' The term is a mass noun. Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simult ...

Garden Railways
''Garden Railways'' (''GR'') was a quarterly American magazine about the hobby of running large-scale trains outdoors, also called garden railroading. During its run, it was the world's leading magazine on that subject.Garden Trains Association website: gardentrains.org Each issue featured hobby news, product reviews, how-to articles, featured railroads from around the world, photo galleries, and much more. Publication ceased after the Fall 2020 issue. ''Garden Railways'' magazine began publication in 1984 by Sidestreet Bannerworks. The magazine evolved from the company's newsletter, the ''Sidestreet Banner'', which dealt primarily with the small scale live-steam locomotives that the company was importing at that time. Marc Horovitz was the Editor and Barbara Horovitz the Horticultural Editor. The first issues of ''Garden Railways'' were published in black-and-white. Text was generated on a typewriter. In 1985, a primitive IBM computer and a daisy-wheel printer were acquired, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
