I'm trying to create a marble run with an array and a curve modifier to create the track. But as you can see the rail won't hold the marble because of its rotation. The rail is following a Bezier curve.

How can I make the rail to be more parallel with the plan so the marble won't get ejected ?

Oh this one's easy.
Just change the curve twist method to Z-Up.
