GraviTrax® Trax

Are the tracks made of metal?
No, the track rails are made of grey-coloured hard plastic.

In which set are the long curved rails included? What is their function?
The long curved tracks are included in the Tunnel Extension Set. These tracks are really helpful to increase the speed of the ball by using the force of gravity.

In which set are low and thin rail included? Do these influence the speed of the marble?
Both these rails are included in the Bridges Extension Set. While the thin rail accelerates the ball, the extra long slow rail slows it down.
