The 9 V system ran from 1991 to 2006 and is still a favourite with LEGO train fans. The rails have metal tops that carry the current from a speed regulator to a motor under the locomotive, so trains could run without batteries for as long as they stayed on the track. It started with 4558 Metroliner in 1991.
1996 LEGO Sets
1996 marked LEGO’s early digital pivot with the creation of LEGO Media and the launch of LEGO.com, establishing the company’s online presence. LEGO Technic was rebranded for global consistency, and several new themes expanded creative play. Wild West explored frontier adventures, Dark Forest revived outlaw factions within Castle, and Time Cruisers combined multiple eras through time travel. Exploriens emphasized scientific exploration within Space, while Pirates introduced the Imperial Armada, expanding LEGO’s nautical storytelling universe.
