This starter set blends classic GRAVITRAX construction fun with the Power electronics range. The Accessory Controller, Dome Starter and Goal Tile (Trigger + Landing Arena) communicate via signals: as soon as a marble activates the trigger before reaching the goal, a signal is sent to the dome and another marble is released automatically. The result is smooth operation and uninterrupted play without manual restarts.
The modular system lets you freely build, change and expand tracks with additional GRAVITRAX add-ons. Design your own routes, test speed and gravity, and plan anywhere — with the free GraviTrax app you can easily prepare a layout on your phone or tablet and then build it in the real world.
