On most of my routes with double track mine line I run the right hand track one direction and the left the opposite direction.  This means I have a lot of track marks to keep the AI on the correct track.  All of these track marks are labeled.  If I use the priority mark and number it #1 priority would it be necessary to label those marks or would the AI follow the marks?  I would like to to eliminate all those track marks.
Thanks.
