Complete game-ready mining train composition combining a highly modular retro locomotive and a functional mine cart. To ensure optimal performance and a lightweight file, the scene includes one locomotive, one base cart, and three interchangeable ore types (coal, gold vein, gravel), with one ore loaded inside and two placed alongside.

The locomotive features extreme part separation: control panel buttons, bolts, and exterior grilles are detached meshes, while wheel origins are perfectly centered for custom rotation animations.

Fully independent cargo and tools are included, featuring hollow boxes with detachable lids, a hammer, a shovel, a bucket, and a modular barrel with its lid and contents separated into individual objects for precise customization.

The mine cart supports functional mechanics with a rotating body for unloading cargo, a separate tailgate door with correct pivots, and a detached lantern containing a pre-configured light source. Modular rails and two chain types (taut and sagging) are provided to easily link the full train composition.
