Edit: This topic was originally created for Analogs Montu and Kumba. Instead of creating a new topic for each example coaster, I think it's better to put them in a single post for easier access. The original post is preserved below, with the updates after it.
Original Post
In the process of testing newton2, I often create coasters inspired by (but not strict recreations of) famous coasters. Most of the time, I don't finish them, either because there's some issue with the track or I'm too lazy to do so (or both [;)]).
Here are 2 examples (again, I'm not really trying to recreate these rides exactly).
Analog Montu
The main problem with this ride is that the station is not oriented properly in relation to the rest of the track, so at the end of the ride, the train has to travel to far to get back to start. I probably should go back correct that at some point.
Analog Kraken
This one is actually a completed track, I just haven't bothered to support it (a process that I find rather tedious). As you can see by the phantom footers, I was playing a bit with ASG.
Updates
Recoil
For completeness, I've included this, though it's also posted in the above linked newton2 thread.
Small Launched Coaster
Here's a nice example of a launched coaster by Matt:
