When I found this article, I was surprised. Thank you so much, and I am very happy.

I use old curved rail for keep the curved shape. So almost AFOL cannot build.

Do you know "LEGO CUUSOO" ?
I entry my idea "Curved Brock" for it. When I get 1000 votes, LEGO will consider my idea.
Everyone can vote.
