Looks nice. I hope it is not too long of a ride though. Some rides are too short, some too long. I would be pleased if you made it a decent length (as in time).

Why do you want to bother with a rail texture? All it would do is add unnecessary polygons, and probably bring the sim to a grinding halt. And it wouldn't even add much to the ride.
I really like the color scheme and the layout. Looks really good, not sure if this has already been addressed, but is this a looping terrain speed racer or just a "standard" speed racer layout?
I like what I can see of your layout, and I can tell you put a lot of thought into the shaping, but the terrain looks so terribly unrealistic that it really takes away from the ride for me. I suggest looking at some pictures and fixing it up a lot. Make sure it doesn't look like your terrain follows the track, instead of the other way around.
