Adding Regression
Points to the Horizontal Geometry Project
In this chapter, you will use coordinate geometry points to add regression points to the horizontal alignment project. The coordinate geometry points represent data gathered from an existing survey project. These points have been imported into the Bentley Rail Track geometry project.

Overview
In this chapter, you will use a series of geometry commands to establish the beginning elements for a new horizontal
alignment. While Bentley Rail Track provides various methods to create horizontal alignments,
method is used here to demonstrate how these unique commands can be used in a typical railway design.
