Railstone - build on rails!

With this attachment you can build on GraviTrax tracks.

The rail block is clipped onto a normal GraviTrax rail, after which you can continue building directly on top of it. The rail block has a hole so that the balls can also fall through a funnel or free fall onto the rail below.
Works well with "light" components, but elements like the power starter or the elevator are too heavy for the track and the holding curve stones.
