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.
1968 LEGO Sets
In 1968, LEGO introduced a new box design, featuring "idea book"-style images on both the front and back, while the now-familiar LEGO logo was moved to the side of the packaging. This design was similar to the approach Samsonite had used for several years. As LEGO continued its transition to a larger and more standardized scale, many Basic sets were updated to reflect this modern scale, while older sets with smaller scales were phased out.
