The LEGO Factory theme, active from 2005 to 2008, included the Trains subtheme, which featured fan-designed sets. The 10183 Hobby Trains set, released in 2007, is a standout set in this subtheme. It was designed by LEGO fans and contains 1,080 pieces that can be used to build a variety of train models, including a steam locomotive, a diesel engine, and various railcars. The set also includes a selection of tracks and various train-related accessories. Hobby Trains exemplified the LEGO Factory's goal of encouraging creativity and customization, allowing builders to create multiple unique train configurations.
