Interchange Management

Purpose | Screen Images | Data Description | Function Descriptions | How to Use


An interchange is a track segment or set of track segments that connect two or more Divisions. If you have more than one Division on your layout then you need at least one Interchange on your layout. If you support commerce with industries not on your layout then you need at least one interchange to connect with these foreign industries.

Screen Images:

This figure shows the Interchanges on my railroad. The lower pane shows the Divisions interconnecting at the (my) Baltimore Interchange. The Gray Division is part of the Chesapeake Railroad on my layout. The Main Division is on a friend's layout that I use to forward traffic to his railroad or other railroads connected to his railroad using MLO.
