Railway modelling (UK, Australia and Canada) or Model railroading (US) is a hobby A hobby horse is a wooden or wickerwork toy made to be ridden just like a real horse . From this came the expression "to ride one's hobby-horse", meaning "to follow a favourite pastime", and in turn, hobby in the modern sense of recreation in which rail transport Rail transport is the conveyance of passengers and goods by means of wheeled vehicles running along railways or railroads. Rail transport is part of the logistics chain, which facilitates international trade and economic growth. Rail transport is capable of high capacity and is energy efficient, but lacks flexibility and is capital intensive systems are modelled at a reduced scale A scale model is a representation or copy of an object that is larger or smaller than the actual size of the object . Very often the scale model is smaller than the original and used as a guide to making the object in full size. Scale models are built or collected for many reasons, or ratio A ratio is an expression that compares quantities relative to each other. The most common examples involve two quantities, but any number of quantities can be compared. Ratios are represented mathematically by separating each quantity with a colon – for example, the ratio 2:3, which is read as the ratio "two to three". The quantities. The scale models A scale model is a representation or copy of an object that is larger or smaller than the actual size of the object . Very often the scale model is smaller than the original and used as a guide to making the object in full size. Scale models are built or collected for many reasons include locomotives A locomotive is a railway vehicle that provides the motive power for a train. The word originates from the Latin loco – "from a place", ablative of locus, "place" + Medieval Latin motivus, "causing motion", and is a shortened form of the term locomotive engine, first used in the early 19th century to distinguish, rolling stock Rolling stock is the collective term that describes all the vehicles that move on a railway. It usually includes both powered and unpowered vehicles, for example locomotives, railroad cars, coaches and wagons. Rolling stock is considered to be a liquid asset, or close to it, since the value of the vehicle can be readily estimated and then shipped, streetcars A tram, tramcar, trolley, trolleycar, or streetcar is a railborne vehicle, of lighter weight and construction than a train, designed for the transport of passengers within, close to, or between villages, towns and/or cities, on tracks running primarily on streets. Certain types of cable car are also known as trams, tracks Below the ballast is a subgrade which may be the surface of the natural ground, or may have some geotechnical system installed to improve ground stability and drainage. The subgrade may loosely be considered to be part of the "track" but the subgrade with the track itself is more properly said to form the infrastructure, signalling A signal is a mechanical or electrical device erected beside a railway line to pass information relating to the state of the line ahead to train drivers/engineers. The driver interprets the signal's indication and acts accordingly. Typically, a signal might inform the driver of the speed at which the train may safely proceed, or it may instruct, and roads, buildings, vehicles, model figures, lights, and features such as streams, hills and canyons.
The earliest model railways are the 'carpet railways' in the 1840s. Electric trains appeared around the turn of the 20th century. But these were crude likenesses. Model trains today are more realistic. Today modellers create model railway / railroad layouts, often recreating real locations and periods in history.
