Railway modelling is a hobby that involves creating miniature representations of railways, including trains, tracks, and landscapes. Enthusiasts build detailed layouts that can range from simple designs to complex systems, often incorporating realistic scenery, buildings, and figures. Modellers use various scales, such as HO or N scale, to represent their trains and environments. This hobby allows individuals to explore aspects of railway history, engineering, and creativity, often leading to participation in clubs and exhibitions where they can showcase their work and share techniques with others.
