I've actually never had problems with rails like that; you just have to learn a different way of hitting them. Try it a few times the next time you're up... basically, you do a hockey-stop slide in front of the rail and just slide right on. So ski up with a decent amount of speed, then a few feet before the rail turn 90 on the slope, like you're sliding to a stop- you'll slide right onto the rail. Once you get used to it, its almost easier than jumping onto a rail, and looks damn smooth. A good thing about it is you can come in real slow and barely slide on the first few times, just for practice- you don't have to commit like you do when jumping onto a rail. Good luck!
