LEGO Power Functions, introduced in 2007, are motorized components that enhance various LEGO sets, including trains. These components include motors, battery boxes, lights, and remote controls, allowing trains to move and be controlled remotely. Notable train sets that feature Power Functions include the "Emerald Night" (10194) from 2009, a highly detailed steam locomotive; the "Maersk Train" (10219) from 2011, a freight train set; and the "Horizon Express" (10233) from 2013, a high-speed passenger train. These sets integrate Power Functions elements to provide realistic train operation, making them popular among LEGO train enthusiasts for their added playability and functionality.
2011 LEGO Sets
2011 introduced Ninjago, which quickly became one of LEGO’s most successful original themes and the foundation of a long-running multimedia franchise. Other launches included Pirates of the Caribbean, coinciding with Disney’s On Stranger Tides, the sci-fi Alien Conquest, and Master Builder Academy, a design-focused building program. LEGO also experimented with digital-physical integration through Life of George, an early augmented reality experience. Collectible Minifigures Series 3–5 strengthened LEGO’s growing collector market, while internal employee-exclusive sets like Moulding Machines became prized rarities. Several themes concluded this year, including Harry Potter, Ben 10, Power Miners, Toy Story, Prince of Persia, Space Police III, and BrickMaster.
