Overview
With the location of the horizontal alignment in place, the next step in designing a railway is the definition of the design grade line or vertical alignment. Before you define the vertical alignment, you extract a profile of the original surface along the horizontal alignment. Then, use the surface profile as a reference for designing the vertical alignment. The profile appears in the drawing file in a rectangular box, referred to as the profile window. As you add segments to the vertical alignment, t
