Hi everybody.
I will show this page: theracingline.net/racingcircuits/ that contains thousands of circuits of the world, inclusive the proposals (for exapmle, the Suzuka original proposal track doesn’t have “8” layout, and a some proposals of the same track had 3 bridges), and all layouts and variants and changes of all tracks.
The page wasn’t update since 2005, but is interesting to learn some curiosities and make Automation tracks.
(FOR THE MODDERS: If this page cannot be posted here, please, move in the correct section. Thanks).
Some examples:
1959 Suzuka proposal:
1960 Hugenholtz 26th August Proposal of Suzuka:
