City Trains is LEGO's main train line since 2006, when 7897 Passenger Train and 7898 Cargo Train Deluxe replaced the old 9 V system. The new trains ran on batteries and plastic track, steered by an infrared remote, and the track kept the curves and switch shapes of the old system so layouts could be mixed.
2015 LEGO Sets
In 2015, LEGO broadened its portfolio with new and returning themes. LEGO Dimensions launched as a toys-to-life crossover linking dozens of franchises including DC, The Lord of the Rings, and Doctor Who. New lines such as Elves, Jurassic World, Scooby-Doo, and Speed Champions debuted, while BIONICLE and Pirates returned in refreshed forms. City marked ten years under its modern branding, and Star Wars supported The Force Awakens with a major release wave. Meanwhile, Teenage Mutant Ninja Turtles and The Hobbit concluded as LEGO shifted toward newer properties.
