The LEGO Trains Service Packs theme was a series of supplementary sets tailored for the LEGO Trains line. Available mainly during the 1980s and 1990s, these packs supplied extra train-related parts, track sections, and accessories. Rather than complete train sets, they provided specific components, allowing users to expand their train layouts, replace missing pieces, or modify existing models.
Trains consists of 39 sets that ran from 1980 to 1996. As of today,
5300 Train Motor 9V is the most valuable Trains set with an estimated new/factory sealed value of $114.
