Free-mo
The Friendship of European railway modellers (german: Freundeskreis Europäischer Modellbahner, FREMO) is a modular rail transport modelling standard. Individual track and scenery modules are built to a common standard and are joined together to make larger model railway layouts. The FREMO standards were created following a meeting in Europe in 1981. Modules are wide, with variable length and viewable from both sides. Each module comes with adjustable legs, to create a uniform top-of-rail height of above floor level. Modules are physically joined together using three holes and hand-tightened M8 bolts with washers and wingnuts. The electrical inter-connection uses two Banana connectors per track bus, over which Digital Command Control (DCC) signalling running at 14 volts is used for train control. Track uses Code 83 rails ( high), with a minimum curve radius of ; representing at 1:87) and fixed track centre-line spacing of ; representing separation at 1:87 scale). Some ...

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 ...

Model Railway Layout
In model railroading, a ''layout'' is a diorama containing scale track for operating trains. The size of a layout varies, from small shelf-top designs to ones that fill entire rooms, basements, or whole buildings. Attention to modeling details such as structures and scenery is common. Simple layouts are generally situated on a table, although other methods are used, including doors. More permanent construction methods involve attaching benchwork framing to the walls of the room or building in which the layout is situated. Track layout An important aspect of any model railway is the layout of the track itself. Apart from the stations, there are four basic ways of arranging the track, and innumerable variations: * ''Continuous loop''. A circle or oval, with trains going round and round. Used in train sets. * ''Point to point''. A line with a station at each end, with trains going from one station to the other. * ''Out and back''. A pear shaped track, with trains leaving a stati ...

ISO Metric Screw Thread
The ISO metric screw thread is the most commonly used type of general-purpose screw thread worldwide. They were one of the first international standards agreed when the International Organization for Standardization (ISO) was set up in 1947. The "M" designation for metric screws indicates the nominal outer diameter of the screw thread, in millimetres. This is also referred to as the "major" diameter in the information below. It indicates the diameter of smooth-walled hole that a male thread (e.g. on a bolt) will pass through easily to create a well-located connection to an internally threaded component (e.g. a nut) on the other side. That is, an M6 screw has a nominal outer diameter of 6 millimetres and will therefore be a well-located, co-axial fit in a hole drilled to 6 mm diameter. Basic profile The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. Each thread is characterized by its majo ...

Washer (hardware)
A washer is a thin plate (typically disk-shaped, but sometimes square) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration ( rubber washer). Washers are usually metal or plastic. High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to brinelling after the torque is applied. Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces. They may also be used in rotating applications, as a bearing. A ''thrust washer'' is used when a rolling element bearing is not needed either from a cost-performance perspective or due to space restraints. Coatings can be used to reduce wear and friction, either by hardening the surface or by providing a solid lubricant (i.e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingnut (hardware)
A wingnut, wing nut or butterfly nut is a type of nut with two large metal "wings", one on each side, so it can be easily tightened and loosened by hand without tools. A similar fastener with a male thread is known as a wing screw or a wing bolt. Types ASME B18.6.9 classifies wing nuts first by manufacturing method and then by style. * Type A are cold forged or cold formed produced in regular, light and heavy dimensional series. * Type B are hot forged solid nuts available in three different wing styles. * Type C are die cast nuts available in three wing styles with variances between regular and heavy dimensional series * Type D are stamped sheet metal nuts available in three wing styles. Usage Bicycles Before the development of quick release skewers, bicycle wheels were held in place with wingnuts. Drum hardware In a drum kit wingnuts and wingbolts are used extensively. * For securing a suspended cymbal on the mounting bolt of a cymbal stand. * For securing an adjustment on a ...

Banana Connector
A banana connector (commonly banana plug for the male, banana socket or banana jack for the female) is a single-wire (one conductor) electrical connector used for joining wires to equipment. The term 4 mm connector is also used, especially in Europe, although not all banana connectors will mate with 4 mm parts, and 2 mm banana connectors exist. Various styles of banana plug contacts exist, all based on the concept of spring metal applying outward force into the unsprung cylindrical jack to produce a snug fit with good electrical conductivity. Common types include: a solid pin split lengthwise and splayed slightly, a tip of four leaf springs, a cylinder with a single leaf spring on one side, a bundle of stiff wire, a central pin surrounded by a multiple-slit cylinder with a central bulge, or simple sheet spring metal rolled into a nearly complete cylinder. The plugs are frequently used to terminate patch cords for electronic test equipment such as laboratory power ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

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] |
