Edit: I've fixed the redstone problems that were causing the cart to stop. I also debated updating some of the things I wish I'd done better, but decided against it. This was done for a contest, so I figure all the structures should stay the way they were at the end of the deadline.

I really wish I'd had more time to devote to this project.
Through a mixture of procrastination, other obligations, and a whole bunch of things suddenly deciding to not work during the last week, I pretty much ran out of time to do what I wanted with this. The end result is much more rushed than I would have liked.
I'm still proud of the general concept, though, and think you guys could have some fun with it, so here goes. :)

The style is supposed to be steampunk, but with a bit of artistic liberty.
The idea of a roller coaster seemed to scream "steampunk" to me. Hopefully you guys like the result.
