Expand your GRAVITRAX marble run with thrilling passages through dark tunnels. The Tunnels set adds curves, intersections, vertical connections, and free-fall rails that take every build to the next level. Ideal for creative builders who want more speed, strategy, and fun. Starter set required.
With the Ravensburger GraviTrax Tunnels expansion, let the marbles “disappear” for a moment and reappear unexpectedly. Create hidden passages, inter-floor connections, and dramatic speed changes using long rails and free-fall openings. The result is an even more dynamic and visually striking marble run.
The set is fully compatible with all components of the RAVENSBURGER GraviTrax system and expands your building options with new routes and interactions. Build original circuits, test gravity, and foster logical thinking, spatial imagination, and technical creativity.
- More track variants: tunnel curves, straights, and intersections for cleverly connected passages.
- Vertical connections: two shafts for smooth elevation changes between levels.
- Dramatic moments: long rails with a free-fall opening and catch baskets for safe landings.
- Easy integration: compatible with other expansions for endless combinations and ideas.
