LEGO Trains is one of the longer running themes that dates back from 1966 and ran up until 2006. During its run there were multiple sets released running on various power platforms from 4.5volt, to 9 and 12 volt sets. Later in 2011 LEGO released additional train sets using RC and Power Functions controllers under different themes like City.
1970 LEGO Sets
1970 marked a period of transition and consolidation for LEGO. The company began reclaiming U.S. market rights from Samsonite following founder Jesse Shwayder’s death, leading to full control by 1973. In Italy, LEGO responded to import restrictions by launching Minitalia, a localized line produced from 1970 to 1975. The long-running Town Plan theme was discontinued as LEGO moved toward standardized scale and unified play systems. While largely a structural year, these shifts laid the groundwork for the innovations of the mid-1970s.
