Model railroads are miniature versions of rail systems that enthusiasts create for hobby or display purposes. They typically consist of scaled-down models of trains, tracks, landscapes, buildings, and other elements found in real railroad operations. Model railroading involves various aspects such as design, building, and operating these miniature systems, and it can encompass a wide variety of scales (sizes), from HO scale (1:87) to N scale (1:160) and larger gauges like G scale.
