LEGO 340-3 Railroad Control Tower, also known as Signal Box or Block House, is a Classic Building set released in 1968 that contains 86 pieces. The set builds a vintage railroad control tower based on the type of structure used at rail junctions and yards to monitor operations and switch tracks. It is notable for its exclusive green baseplate, which appeared only in this set, along with early LEGO elements such as arrow-shaped windows and doors with side knobs. These parts reflect the design style of LEGO’s late 1960s train-era building sets. Based on current trends, this set could be valued near $619 within the next year.
