The Segment Type dialog allows you to define track segment types. You need to enter at least one segment type before making entries in the Track Segment table.
The segment type is used to record attributes of track segments. For example, the types "JOINTED" and "CWR" can be used to label areas of jointed and continuous welded track. If you have no need of the segment type field, you may use a single segment type labeled "SEGMENT".
