LEGO released a number of train sets under the World City theme from 2003 to 2004. A total of eleven sets were released, three of them being promotional polybag sets containing just minifigures. The trains in the World City theme were white with a green stripe and were both passenger and cargo trains.
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.
