MAXi Train is a remix based on the Mini Train Collection of BamBam Design, applying a 2.5x upscale ratio to make it maxiiii…

The MAXi Train series evolves with the addition of a custom motorized base, designed to bring your dioramas to life. This compact yet powerful box houses a discreet motor mechanism, allowing the train to glide smoothly around your miniature world—adding a dynamic layer of realism and movement to the scene. Perfectly sized to integrate with all MAXi Train dioramas, the motorized base maintains the collection’s clean aesthetic while enhancing its interactivity. Whether you're watching the Amtrak circle Washington or a cable car loop through San Francisco, this motion system adds a new dimension to the experience. Like every element in the series, the motorized box balances design, precision, and charm — an essential upgrade for any collector looking to animate their favorite cities.

This new design is based on the Mini Train Collection of BamBam Design (https://linktr.ee/bambamdesign). This model is 2.5X bigger than usual BamBam Design Mini Train Collection. Don’t modify the scale of this model as the motor, battery and motherboard won’t fit anymore. This design is compatible with all 250% scale of BamBam Design Mini Train Collection.
