Supplement to the O-rails of the tunnel extension.
The O-rails from the tunnel extension are very cool, but unfortunately they are not so easy to use multiple times if you don't want the ball to disappear into the hole immediately. The jump rail makes it easier to cross the hole with a small jump and only allows the ball to fall through from the other side.
The design of the jump rail offers many practical and clever ways of installing it into the track.
The jump rail is as long as a 3-track and of course fits into all GraviTrax bricks.
