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.
1978 LEGO Sets
In 1978, LEGO introduced several groundbreaking themes that would define the company for decades. One of the most significant developments was the expansion of the LEGO Town theme, which built upon previous city-focused sets. This year, LEGO introduced new models of public transportation, including buses and taxis, further enhancing the realism and playability of urban environments.
