Lionel Built To Order (BTO) trains are limited-production models designed for collectors and enthusiasts seeking unique and hard-to-find locomotives. Created to reduce overproduction, BTO releases are manufactured in smaller quantities, making them more exclusive than standard Lionel train releases.
Because of their limited availability, Lionel BTO locomotives are often more difficult to find after their initial release. Trainz offers a select inventory of Built To Order trains, giving collectors the opportunity to purchase rare Lionel models and add distinctive pieces to their layouts.
