LEGO Trains

Lego Trains is a product range and theme of the construction toy Lego, which incorporates buildable train sets. The Lego Trains theme became a sub-theme of Lego City in 2006. Products in the range have included locomotives, tracks, rolling stock, stations, signal boxes, and other track-side buildings and accessories. The theme is popular among adult fans, as well as children, and has spawned international associations and conventions. The train system is sometimes referred to as 'L-gauge' among Lego fans, in reference to traditional model railway scales. Lego trains use a nominal gauge of 37.5 mm (1+15⁄32 in), based on 5-stud track centerlines gauge, corresponding with a circa 1:38 scale.
