NMRA
The National Model Railroad Association (NMRA) is a non-profit organization for those involved in the hobby or business of model railroading. It was founded in the United States in 1935, and is also active in Canada, Australia, the United Kingdom, and the Netherlands. It was previously headquartered in Indianapolis, Indiana, and was based in Chattanooga, Tennessee next to the Tennessee Valley Railroad Museum (TVRM) from 1982 to 2013 and has since relocated to Soddy Daisy. General The classifications listed below are from the A.A.R. Individual roads may use other designations. Illustrations show a typical member of the class detailed underneath the following a class description indicates a rare or obsolete type. Industry involvement The best-known activity of the NMRA is the defining of standards, and advisory documents known as Recommended Practices (RP), for model railroad equipment. Many standards defined by the NMRA are widely followed by the industry and modellers, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail Transport Modelling Standards
This page lists the most relevant model railway scale standards in the world. Most standards are regional, but some have followers in other parts of the world outside their native region, most notably NEM and NMRA. While the most significant standardised dimension of a model railway scale is the gauge, a typical scale standard covers many more aspects of model railways and defines scale-specific dimensions for items like catenary, rolling stock wheels, loading gauge, curve radii and grades for slopes, for instance. Scale standards NEM MOROP (the European federation of national model railway associations) is a European organisation which publishes NEM-standards. NEM-standards are used by model railway industry and hobbyists in Europe. The standards are published in French and German and both versions have an official status. Unofficial translations in English from third parties exist for certain NEM-standard sheets. Model railway scales and gauges are standardized in NEM 0 ...

Digital Command Control
Digital Command Control (DCC) is a standard for a system to operate model railways digitally. When equipped with Digital Command Control, locomotives on the same electrical section of track can be independently controlled. The DCC protocol is defined by the Digital Command Control Working group of the National Model Railroad Association (NMRA). The NMRA has trademarked the term DCC, so while the term ''Digital Command Control'' is sometimes used to describe any digital model railway control system, strictly speaking it refers to NMRA DCC. History and Protocols A digital command control system was developed (under contract by Lenz Elektronik GmbH of Germany) in the 1980s for two German model railway manufacturers, Märklin and Arnold. The first digital decoders that Lenz produced appeared on the market early 1989 for Arnold (N) and mid 1990 for Märklin (Z, H0 and 1; Digital=). Märklin and Arnold exited the agreement over patent issues, but Lenz continued to develop the system. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.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 cheape ...

Chattanooga, Tennessee
Chattanooga ( ) is a city in and the county seat of Hamilton County, Tennessee, United States. Located along the Tennessee River bordering Georgia, it also extends into Marion County on its western end. With a population of 181,099 in 2020, it is Tennessee's fourth-largest city and one of the two principal cities of East Tennessee, along with Knoxville. It anchors the Chattanooga metropolitan area, Tennessee's fourth-largest metropolitan statistical area, as well as a larger three-state area that includes Southeast Tennessee, Northwest Georgia, and Northeast Alabama. Chattanooga was a crucial city during the American Civil War, due to the multiple railroads that converge there. After the war, the railroads allowed for the city to grow into one of the Southeastern United States' largest heavy industrial hubs. Today, major industry that drives the economy includes automotive, advanced manufacturing, food and beverage production, healthcare, insurance, tourism, and back office ...

Rail Transport Modelling 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 ...

Normen Europäischer Modellbahnen
german: Normen Europäischer Modellbahnen (french: Normes Européennes de Modélisme ferroviaires, literally European Standards for Model Railways, known in the UK as Normal European Modelling Standards (NEM Standards)) are standards for model railroads, issued by the MOROP. Standards The NEM standards are defined and maintained by the Technical Commission of the MOROP in collaboration with model railroad manufacturers. The NEM standards define the model railroad scales and guide :Model railroad manufacturers, manufacturers in creating compatible products and assist modellers in constructing model railroad layouts that operate reliably. The standards cover areas like suggested grade (slope), grades, railroad switch, turnout radii, wheel profiles, coupling designs and Digital Command Control (DCC) and are mostly scale specific. A fundamental principle in NEM standards are compromises in the exact scale reduction ratio in order to favour operational reliability of model railroad syst ...

Model Railroad
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. The scale models include locomotives, rolling stock, streetcars, tracks, signalling, 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. Model trains today are more realistic, in addition to bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk Southern Railway
The Norfolk Southern Railway is a Class I freight railroad in the United States formed in 1982 with the merger of Norfolk and Western Railway and Southern Railway. With headquarters in Atlanta, the company operates 19,420 route miles (31,250 km) in 22 eastern states, the District of Columbia, and has rights in Canada over the Albany to Montréal route of the Canadian Pacific Railway. NS is responsible for maintaining , with the remainder being operated under trackage rights from other parties responsible for maintenance. Intermodal containers and trailers are the most common commodity type carried by NS, which have grown as coal business has declined throughout the 21st century; coal was formerly the largest source of traffic. The railway offers the largest intermodal rail network in eastern North America. NS was also the pioneer of Roadrailer service. Norfolk Southern and its chief competitor, CSX Transportation, have a duopoly on the transcontinental freight rail li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Model Railroader
''Model Railroader'' (''MR'') is an American magazine about the hobby of model railroading. Founded in 1934 by Al C. Kalmbach, it is published monthly by Kalmbach Media of Waukesha, Wisconsin. Commonly found on newsstands and in libraries, it promotes itself as the oldest magazine of its type in the United States, although it is the long-standing competitor to ''Railroad Model Craftsman,'' which - originally named ''The Model Craftsman'' - predates MR by one year. ''MR'' is considered to be a general-interest hobby magazine, appealing to a wide range of hobbyists, rather than specializing in a particular scale, or facet of the hobby (such as prototype operations or scratch building and kitbashing). ''Model Railroader'' covers a variety of scales and modeling techniques for engines, rolling stock, right-of-way, structures, and scenery. It reviews products including ready-to-run models as well as kits, tools and supplies. The magazine presents blueprints and photographs of prototyp ...
