Try the flip component.

To be clear, the List component lists any one of the curves that will be used in the loft and is plugged into the "G" input of the Flip component to act as a guide for all the other curves that they have the same direction.

the list item doesn´t work, it gives me an error. The problem is that in some steps before i made the lines from intersection points. so the end and startpoints are not on the same site of my railcurve, so the loft cross it.

Well this is the point of the List component, to select only one of all the curves that will be involved in the Loft to act as a guide curve for the Flip component. Can you please post an image of the definition. You say the List component doesn't work, is it red or orange? Image would help. I will say though, I have had cases where the Flip component doesn't work as suspected with a guide direction.

Put a 0 in the "i" input of the list item component.

Thats very basic, i think that you should read and print the primer: http://www.grasshopper3d.com/page/tutorials-1

As Manuel has mentioned, you need to enter a number into the "I" input. In this case you can select between 0-131.
