There's a very promising game/tool that just got the beta released. It's called Theme Park Studio. If you're wondering why I am talking about this random game is because it is going to blow the amusement park genre away. CUSTOM FLAT RIDE CREATOR

Also the Turbo is in the game. There will be rollercoasters in the game at a later point, but at the moment it's just got the architectural tools. Please have a geeser at what this has to offer. The other flat rides available at the moment are a Double Story Carousel, Matterhorn (the proper old school and far more superior version), Ferris Wheel, Intamin Gyro Swing, Intamin 1st Gen Drop Tower, Hurricane and Chance Turbo. Just a heads up, the rides are static at the moment, but the rides will be active and ready to ride in the next phase, also the CFR creator will be up and running then too.
