GraviTrax Tunnels (Expansion)
Ravensburger 27623 GraviTrax Tunnels (Expansion)
The GraviTrax Tunnels Expansion adds covered route sections that temporarily hide a moving marble. Straight, curved and vertical tunnel components create surprise, support level changes and give builders new ways to connect an existing track.
Key Features
- Adds straight, curved and vertical tunnel sections
- Temporarily hides the marble as it moves through the route
- Supports concealed turns and level changes
- Creates new route-planning and speed challenges
- Requires a GraviTrax Starter Set
Why Add the Tunnels Expansion?
Tunnels change both the appearance and behaviour of a familiar layout. Children must predict where the hidden marble will reappear, then adjust the surrounding track to manage speed and direction.
Compatibility and Expansion
The Tunnels Expansion is made for an existing GraviTrax Starter Set. It cannot form a complete marble run on its own. Browse the GraviTrax collection for related sets and expansions.
