With drop bridges, you’ll take your GRAVITRAX builds to the next level. The bridges activate automatically when the marble passes, connecting two parts of the track and adding both dynamism and a striking effect. The box includes rails of various lengths, including extra-long and slowing rails, so you can easily fine-tune speed and ensure a smooth ride along the whole course.
This modular add-on from RAVENSBURGER is ideal for builders young and old who want to experiment with speed, gravity, and construction. Combine it with other expansions to create original tracks with clever obstacles and spectacular actions.
