About LEGO Classic Jumbo Bricks
The LEGO Classic Jumbo Bricks theme from the 1960s consisted of sets with larger-than-standard LEGO bricks. These oversized bricks were designed primarily for younger children, providing a safe building experience and serving as an introduction to the LEGO system before transitioning to regular-sized LEGO bricks. The sets in this theme focused on basic construction and simple designs, catering to the developmental needs and motor skills of the target age group.
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.
