Ride On Rail
A ride on rail has a snow ramp leading up to it with no gap. This negates the need to ollie up onto the feature, making it easy for beginners.
Flat Rail
The flat rail is a step up from the ride on. It incorporates a gap at the beginning of the features and then runs straight across level ground. It is the easiest to balance on.
Down Rail
A down rail is angled down the mountain. This makes the balance of your body slightly different as you ride it. You want to make sure to keep your body weight centered as up and down as possible, which requires shifting your weight once you are on the rail.
Up Rail
An up rail is pointed up, or away from the slope, of the mountain. You will rarely see it by itself, more likely it will be part of a multi-angle feature, such as an up-flat-down rail.
Kinked Rail
A kinked rail incorporates multiple straight features, each section separated by a kink where the rail changes direction. An up-flat-down rail is an example. Keeping your balance over the kink adds an extra level of difficultly to these features. In order to keep your balance, bend your knees to absorb the impact of the kink.
Curved Rail
A curved rail has an arc instead of an angled kinked. Common examples are the C-rail, S-rail and rainbow rail.
