About LEGO Classic Building
The LEGO Classic Building theme from the 1960s consisted of sets that focused on general construction and architectural design using standard LEGO bricks. Unlike specialized themes, the Classic Building sets from this era emphasized foundational building techniques and allowed for the creation of various structures and designs. It represented one of LEGO's early efforts to promote versatile brick-based construction.
1966 LEGO Sets
1966 marked one of LEGO’s greatest milestones with the launch of the LEGO Train system. Sold in 42 countries, the range introduced a 4.5V battery-powered system and a 12V electrified track version for advanced users. Specialized parts such as hook couplers, flanged wheels, and curved track debuted alongside sets like 113, 114, and 115, setting a new standard for mechanical play. Accessories soon followed, including a whistle-controlled motor unit. These innovations, led by LEGO Futura and the process development lab, established Trains as one of LEGO’s most enduring product lines.
