Maryland Route 27 (1920s-1930s)
O scale (or O gauge) is a scale commonly used for toy trains and rail transport modelling. Introduced by German toy manufacturer Märklin around 1900, by the 1930s three-rail alternating current O gauge was the most common model railroad scale in the United States and remained so until the early 1960s. In Europe, its popularity declined before World War II due to the introduction of smaller scales. O gauge had its heyday when model railroads were considered toys, with more emphasis placed on cost, durability, and the ability to be easily handled and operated by pre-adult hands. Detail and realism were secondary concerns, at best. It still remains a popular choice for those hobbyists who enjoy running trains more than they enjoy other aspects of modeling, but developments in recent years have addressed the concerns of scale model railroaders making O scale popular among fine-scale modellers who value the detail that can be achieved. The size of O is larger than OO/HO layouts, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail Transport Modelling Scale 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 ...

MTH Electric Trains
MTH Electric Trains is an American toy train and model railroad designer, importer, and manufacturer. A privately held company based in Columbia, Maryland, MTH was formerly known as Mike's Train House. Early career MTH's founder, Mike Wolf, started assembling and selling trains at the age of 12 in 1973 for Williams Electric Trains, which had begun producing reproductions of vintage trains manufactured by Lionel Corporation, in the early 1970s. By 1980, Wolf was operating a mail order business selling Williams trains and parts out of his bedroom in his parents' home. When Williams decided to end its line of Lionel Standard gauge and O gauge reproductions, Wolf bought the tooling and continued building the replicas. Although many published reports have stated that Williams had acquired original Lionel tooling, both Wolf and Jerry Williams deny this claim. From 1983 to 1987, MTH marketed the reproduction trains on its own. In 1987, Lionel approached Samhongsa, MTH's subcontractor in ...

Narrow-gauge Railway
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard-gauge railway, standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with Minimum railway curve radius, 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, Indone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Standard Gauge
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Gauge
In rail transport, track gauge (in American English, alternatively track gage) is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A '' loading gauge'' is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A ''structure gauge'' specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. Uses of the term The most common use of the term "track gauge" refers to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. For example, the NEM standards for Digital Command Control (DCC) have been defined by working with the NMRA. The NEM standards and other official documents of MOROP are published in French and German. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scale (ratio)
The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original. Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. In such cases the scale is dimensionless and exact throughout the model or drawing. The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale. Thus on an architect's drawing one might read 'one centimeter to one meter', 1:100, 1/100, or . A bar scale would also normally appear on the drawing. Colon may also be substituted with a specific, slightly raised ratio symbol , ie. . General representation In general a representation may involve more than one scale at the same time. For example, a drawing showing a new road in elevation might use different horizontal and vertical scales. An elevation of a bridge might be annotated with arrows with a length proport ...

Meccano Ltd
Meccano Ltd was a British toy manufacturing company, established in 1908 by Frank Hornby in Liverpool, England, to manufacture and distribute Meccano and other model toys and kits created by the company. During the 1920s and 1930s it became the biggest toy manufacturer in the United Kingdom and produced three of the most popular lines of toys in the twentieth century: Meccano, Hornby Trains and Dinky Toys. Financial problems beset the company in the early 1960s and Meccano Ltd was taken over by Lines Bros Ltd in 1964. History :''See Frank Hornby for the events leading up to the formation of Meccano Ltd''. In 1901 Frank Hornby, a clerk from Liverpool, England, invented a new construction toy called "Mechanics Made Easy", which soon became known as Meccano. To manufacture and distribute Meccano, Hornby needed to raise capital to invest in factory and plant, and this resulted in the establishment of Meccano Ltd in 1908, with Hornby as the sole proprietor. A factory was acquired in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
