Carriage expansion
The official store description says players can add carriages, crafting stations, and storage to build the train into a mobile base. This is a progression system, not merely visual customization.
Developer interviews add two constraints: walls use grid-snapped construction, and more carriages require more engine power because upgrades govern speed and pulling weight. The team does not expect extreme multi-storey structures.
- Increase usable train space
- Host production facilities
- Add storage
- Build walls on a snapped grid
- Balance train length against power and pulling capacity
