I know alpine coasters are designed to work with terrain because they can only go seven tiles off the ground, but it's still way too short. Real-life alpine coasters are decently long, so I don't think they're designed to be short & sweet like the mini coaster, steeplechase, junior coaster, & others. I'm probably doing something wrong, but I have no idea what it could be. How do you build this coaster & how do you make it longer?
