Railway modelling or model railroading is a hobby in which rail transport systems are modelled at a reduced scale.
A scale model is a physical model which is geometrically similar to an object. Scale models are generally smaller than large prototypes such as vehicles, buildings, or people; but may be larger than small prototypes such as anatomical structures or subatomic particles. Models built to the same scale as the prototype are called mockups.
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.
HO or H0 is a rail transport modelling scale using a 1:87 scale. It is the most popular scale of model railway in the world. The rails are spaced 16.5 millimetres (0.650 in) apart for modelling 1,435 mm standard gauge tracks and trains in HO.
American Flyer is a brand of toy train and model railroad manufactured in the United States.
N scale is a popular model railway scale. Depending upon the manufacturer, the scale ranges from 1:148 to 1:160. Effectively the scale is 1:159, 9 mm to 1,435 mm, which is the width of standard gauge railway. However the scale may vary to simulate wide or narrow gauge rail. 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 at 1:120 scale with a Track gauge of 12 mm between the rails. It is placed between HO scale (1:87) and N scale (1:160). Its original purpose, as the name suggests, was to make a train set small enough to assemble and operate on a tabletop.
Bachmann Branchline is a British OO gauge model railway brand manufactured by Bachmann Europe PLC, a subsidiary of Bachmann Industries, and is used for British outline OO scale model railways.
OO9, often also denoted as 009 or 00-9 is a model railway scale and gauge combination of 4 mm scale and 9 mm gauge tracks, which models a prototype track gauge of 2 ft 3 in. It is a common choice in the United Kingdom for the modelling of narrow-gauge railways whose prototype gauges lie approximately between 2 ft and 2 ft 6 in. The 9 mm track gauge is used by N gauge model railways, a common commercial scale, which means that a selection of wheels, track, and mechanisms is readily available.
Z scale is one of the smallest commercially available model railway scales (1:220), with a track gauge of 6.5 mm / 0.256 in. Introduced by Märklin in 1972, Z scale trains operate on 0–10 volts DC and offer the same operating characteristics as all other two-rail, direct-current, analog model railways. Locomotives can be fitted with digital decoders for independent control. Model trains, track, structures, and human/animal figures are readily available in European, North American, and Japanese styles from a variety of manufacturers.
Bachmann Industries is a Bermuda-registered, Chinese-owned company, globally headquartered in Hong Kong; specialising in model railroading.
Railroad Model Craftsman is an American magazine specializing in the hobby of model railroading. The magazine is published monthly by White River Productions, which acquired the title from Carstens Publications in 2014. Its first issue in March 1933 was called The Model Craftsman because it covered other areas of scale modeling as well. Founded by Emanuele Stieri, it was second editor Charles A. Penn who helped grow the company and lead the publication towards the hobby of scale models. In April 1949 it changed its focus to model trains and changed its name to Railroad Model Craftsman to reflect this change in editorial content. While it can claim to be the oldest model railroading magazine in continuous publication in the United States, rival Model Railroader counters with the tagline "Model railroading exclusively since 1934." Over the years, several other titles have been folded into the publication, including Toy Trains, Electric Trains and Hobby Railroading, Miniature Rail Roading, Model & Railway News, and The O Gager.
A coupling or coupler is a mechanism, typically located at each end of a rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train.
Athearn is a United States manufacturer of model railroad equipment, produced and distributed by American hobby manufacturer Horizon Hobby, Inc. of Champaign, Illinois.
Wm. K. Walthers, Inc. is a manufacturer and distributor of model railroad supplies and tools.
Life-Like was a manufacturer of model trains and accessories. In 1960, the company purchased the assets of the defunct Varney Scale Models and began manufacturing model trains and accessories under the name Life-Like in 1970. In 2005 the parent company, Lifoam Industries, LLC, chose to concentrate on their core products and sold their model railroad operations to hobby distributor Wm. K. Walthers. Today, the Life-Like trademark is used by Walthers for HO Scale Buildings.
Lima S.p.A. is an Italian brand and former manufacturing company of model railways. The company was headquartered in Vicenza for almost 50 years, from the early 1950s until the company ceased trading in 2004. Lima was a popular, affordable brand of 00 gauge and N gauge model railway material in the UK, more detailed H0 and N gauge models in France, Germany, Italy, Switzerland, and the United States as well as South Africa, Scandinavia and Australia. Lima also produced a small range of 0 gauge models. Lima partnered with various distributors and manufacturers, selling under brands such as A.H.M., Model Power, and Minitrain. Market pressures from superior Far Eastern produce in the mid-1990s led to Lima merging with Rivarossi, Arnold, and Jouef. Ultimately, these consolidations failed and operations ceased in 2004.
Atlas Model Railroad Company, Inc. makes scale models in N scale, HO scale, and O scale. The company is based in Hillside, New Jersey, United States. They produce a wide variety of locomotives, rolling stock, and vehicles. Atlas is well known for their flex track and codes 55, 80, 83 and 100 track. Atlas also produces a line of compatible structures and bridges.
Brass models, made of brass or similar alloys, are scale models typically of railroad equipment, bridges and occasionally, of buildings. Although die-cast or plastic models have made considerable advances in late 1990s and continue to improve, brass models offer finer details. Brass models, considered to be collector's pieces and museum quality finish, are often used for display purposes rather than model railroad operations. However, these can be made fully operational and many railroaders do use them on their model railroads. They are generally considerably more expensive than other types of models due to limited production quantities and the "handmade" nature of the product itself.
Janney couplers are a semi-automatic form of railway coupling that allow rail cars and locomotives to be securely linked together without rail workers having to get between the vehicles. They are also known as American, AAR, APT, ARA, MCB, knuckle, Buckeye, tightlock, Henricot or Centre Buffer Couplers.
