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.
2005 LEGO Sets
2005 marked the formal introduction of LEGO City, succeeding Town as LEGO’s modern urban theme. Star Wars minifigures transitioned from classic yellow to light nougat skin tones, aligning with other licensed lines. New themes included Dino Attack (Dino 2010 in Europe) and Vikings, while LEGO Star Wars: The Video Game debuted, establishing the long-running TT Games franchise. The year also celebrated 50 years of the LEGO System and growing digital expansion.
