Model train

Railway modelling (UK, Australia and Ireland) or model railroading (US and Canada) is a hobby in which rail transport systems are modelled at a reduced scale.

The scale models include locomotives, , streetcars, tracks, signalling and landscapes including: countryside, roads, buildings, vehicles, model figures, lights, and features such as rivers, hills, and canyons.

The earliest model railways were the 'carpet railways' in the 1840s. Electric trains appeared around the start of the 20th century, but these were crude likenesses. Model trains today are more realistic. Today modellers create model railway layouts, often recreating real locations and periods throughout history.

Involvement ranges from possession of a train set to spending hours and large sums of money on a large and exacting model of a railroad and the scenery through which it passes, called a "layout". Hobbyists, called "railway modellers" or "model railroaders", may maintain models large enough to ride (see Live steam, Ridable miniature railway and Backyard railroad).

Modellers may collect model trains, building a landscape for the trains to pass through. They may also operate their own railroad in miniature. For some modellers, the goal of building a layout is to eventually run it as if it were a real railroad (if the layout is based on the fancy of the builder) or as the real railroad did (if the layout is based on a prototype). If modellers choose to model a prototype, they may reproduce track-by-track reproductions of the real railroad in miniature, often using prototype track diagrams and historic maps.
