TECHNIC is one of The LEGO Company's main lines based on creating detailed model machines and mechanical toys with specialized beams, axles, gears and connectors. The theme was first introduced as the Expert Builder series in 1977, but was officially renamed as TECHNIC in 1984.
1983 LEGO Sets
In 1983, LEGO refined its mainstays. Castle expanded with knight and soldier assortments that hinted at emerging factions, Town added civic infrastructure and vehicles, and DUPLO broadened early-years play. The 12V Train system gained more rolling stock and control elements, boosting realism.
