Setting the Changeover Node in Route Definition
After creating a through line, establish the changeover node in the Route Definition screen to indicate where the newly created single through line breaks into its original constituent lines.
The X appears in the Label field on the Nodes tab; the changeover node for your through line is established.
Note: The node may have more than one label applied to it. In such cases, add the X to the
field; you do not need to overwrite already exisiting information.
