My first CS set comes from my final attempt to recreate Epcot's Test Track. The set contains 77 pieces including the track covers for the exterior loop, which are to be used with Loubauder's Test Track CTR with the vehicle positioning set to terrain level. Also there are crash test dummies, road signs and other test-ish gadgets for you to use freely. Enjoy!

I found an error in my old set, with the roofs not lining up on the RCT3 squares, so I fixed it, together with a better look 

If you have the old version installed, You'd best just delete them because they don't line up. But you can keep them if you want.
