Railway modelling or model railroading is a hobby in which rail transport systems are modelled at a reduced scale.
A model car, or toy car, is a miniature representation of an automobile. Other miniature motor vehicles, such as trucks, buses, or even ATVs, etc. are often included in this general category. Because many miniature vehicles were originally aimed at children as playthings, there is no precise difference between a model car and a toy car, yet the word 'model' implies either assembly required or the accurate rendering of an actual vehicle at smaller scale. The kit building hobby became popular through the 1950s, while the collecting of miniatures by adults started to pick up momentum around 1970. Precision-detailed miniatures made specifically for adults are a significant part of the market since the mid-1980s.
Brobdingnag is a fictional land, which is occupied by giants, in Jonathan Swift's 1726 satirical novel Gulliver's Travels. The story's main character, Lemuel Gulliver, visits the land after the ship on which he is travelling is blown off course. As a result, he becomes separated from a party exploring the unknown land. In the second preface to the book, Gulliver laments that the publisher misspelled the land's name, which Gulliver asserts is actually called Brobdingrag.
Miniature wargaming is a form of wargaming in which military units are represented by miniature physical models on a model battlefield. The use of physical models to represent military units is in contrast to other tabletop wargames that use abstract pieces such as counters or blocks, or computer wargames which use virtual models. The primary benefit of using models is aesthetics, though in certain wargames the size and shape of the models can have practical consequences on how the match plays out. Miniature wargaming is generally a recreational form of wargaming because issues concerning scale can compromise realism, making it unsuitable for most serious military applications.
A scale model is most generally a physical model of an object that maintains accurate relationships between its important aspects, although absolute values of the original properties need not be preserved. This enables it to demonstrate some behavior or property of the original object without examining the original object itself. The most familiar scale models represent the physical appearance of an object in miniature, but there are many other kinds.
O scale 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.
N scale is a popular model railway scale. Depending upon the manufacturer, the scale ranges from 1∶148 to 1∶160. In all cases, the gauge is 9 mm or 0.354 in. 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, so when calculating the rail or track use 1∶160 and for engines and car wheel base use 1∶148.
TT scale is a model railroading scale, whose name stands for table top.
In miniature wargaming, players enact simulated battles using scale models called miniature models, which can be anywhere from 2 mm to 54 mm in height, to represent warriors, vehicles, artillery, buildings, and terrain. These models are colloquially referred to as miniatures or minis.
A model figure is a scale model representing a human, monster or other creature. Human figures may be either a generic figure of a type, a historical personage, or a fictional character.
A garden railroad or garden railway is a model railway system set up outdoors in a garden. While G is the most popular scale for garden railroads, 16 mm scale has a dedicated and growing following especially in the UK. Model locomotives in this scale are often live steam scale models of British narrow gauge prototypes. 16 mm scale track, the same gauge as O gauge is probably now more popular in the UK than G scale.
Live steam is steam under pressure, obtained by heating water in a boiler. The steam is used to operate stationary or moving equipment.
1:144 scale is a scale used for some scale models such as micro/mini armor. 1:144 means that the dimensions of the model are 1/144 (0.00694) the dimensions of the original life-sized object; this equates to a scale of 1/2 inch per 6 feet of original dimension. For instance, an airplane 30 feet (9.14 m) in length would be a mere 2.5 inches (63.5 mm) long as a 1:144 scale model.
1:43 scale is a popular size of die-cast model cars in Europe, Asia and the US. It has its origins in the British / European O scale for model trains and the rise of certain accessories made for that scale which since have become popular in their own right.
Naval wargaming is a branch of the wider hobby of miniature wargaming. Generally less popular than wargames set on land, naval wargaming nevertheless enjoys a degree of support around the world. Both historical and fantasy rulesets are available.
1:72 scale is a scale used for scale models, most commonly model aircraft, corresponding to one sixth of an inch representing one foot. In other words, 72 of a given model placed end to end would represent the length of the real thing. In this scale, a man who is six feet tall would be exactly one inch in height. The scale was popular for aircraft because small fighters and large bombers were represented, and was practically the only choice of scale if a modeler wanted to have all aircraft types represented in the same scale.
SE scale is a designation used by some modellers to describe miniature (model) trains which run on either Gauge 1 track or O gauge track. In SE scale, 7/8 of an inch equals one foot, which is a ratio of 1:13.7. On 45 mm gauge track this represents real life narrow gauge railways that are 2 ft gauge, while on 32 mm gauge track this represents 18 in railways.
1:18 scale is a traditional scale (ratio) for models and miniatures, in which 18 units on the original is represented by one unit on the model. Depending on application, the scale is also called two third inch scale since 1 foot is represented by 2/3 of an inch.
In musical tuning, a lattice "is a way of modeling the tuning relationships of a just intonation system. It is an array of points in a periodic multidimensional pattern. Each point on the lattice corresponds to a ratio. The lattice can be two-, three-, or n-dimensional, with each dimension corresponding to a different prime-number partial [pitch class]." When listed in a spreadsheet a lattice may be referred to as a tuning table.
