Basic Sets or Universal sets were part of the LEGO Basic theme, which began in the 1970s, was designed to be a more general, non-thematic series of sets. Unlike the themed sets that revolve around specific stories, characters, or concepts (e.g., space, city, or pirates), the Basic theme provided a collection of standard LEGO bricks and pieces, often in a variety of colors. The goal was to encourage free building and creativity without the confines of a specific theme or narrative.
1980 LEGO Sets
In 1980, LEGO significantly expanded the LEGO Train theme, enhancing its realism and functionality with a new 12-volt system. While 12V electric trains had existed in Europe since the late 1960s, the 1980 update introduced remote-controlled points, signals, decouplers, and lights, making LEGO trains more interactive than ever before. This refined system cemented LEGO Trains as one of the company’s most technologically advanced product lines at the time.
