It most definately does and below is a quick piccie to show that it does.
Player train ( in piccie ), has already navigated through the two previous markers i placed ( marker one & marker two ).
You can see that the next destination set is "MARKER THREE", also scenario specific.

This is a very worthwhile fuction, as is the "Set Junction State At Scenario Start" function.
Very handy on the CSX Mainline route, as all junctions are manual.

A positive step forward in RW and as i am not interested in "Free Roam".
This makes "Standard Scenario" creation a little bit easier than it was in RS.
