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.
2004 LEGO Sets
2004 was a pivotal recovery year following financial losses in 2003. LEGO updated its color palette, introducing light nougat for licensed minifigures and brighter grays and browns. The company partnered with Ferrari under LEGO Racers and launched Knights’ Kingdom II, a story-driven reimagining of Castle. QUATRO expanded the preschool range, while World City, Orient Expedition, Spider-Man, and Gravity Games concluded. These shifts, along with strategic licensing, began LEGO’s long-term turnaround.
