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.
1976 LEGO Sets
In 1976, town-focused play deepened with emergency and civic sets—police, fire, and services—while the train range saw continued refinement of 12V equipment and rolling stock. Basic Building Sets emphasized open-ended creativity. Fully fledged Space and Castle themes would follow in 1978.
