LEGO Trains is one of the longer running themes that dates back from 1966 and ran up until 2006. During its run there were multiple sets released running on various power platforms from 4.5volt, to 9 and 12 volt sets. Later in 2011 LEGO released additional train sets using RC and Power Functions controllers under different themes like City.
1997 LEGO Sets
In 1997, the LEGO Group faced significant challenges as it grappled with a changing toy market and internal organizational shifts. While the company introduced its first-ever licensed theme, "Star Wars," laying the groundwork for one of its most successful and enduring lines, it also experienced a dip in sales for the first time since its inception. The LEGO Group recognized the need to innovate and diversify its product offerings beyond traditional brick sets, leading to endeavors in new areas like software and video games, with the launch of LEGO Island, its first PC game. This year marked a period of introspection and transformation for the iconic toy company.
