What are Track Priority Markers?

In Summary:
DotPoint.JPG 'Track priority markers are purple coloured track marker that are invisible in Driver Mode but visible in Surveyor Mode. They are used to direct specific trains through the track section where they are placed
DotPoint.JPG Track priority markers are NOT a substitute for Driver Commands with trackmarks or for Interlocking Towers
DotPoint.JPG Track priority markers will be IGNORED if there is no alternative path for a redirected train

Adding a Track Priority Marker

PriorityMarker1.png

Steps.PNG Steps:
  1. . Open the Track Tool
  2. . Select the Trackmark button
  3. . Select the Track Priority Marker
  4. . Click on the track location where the priority marker is to be placed


This will place the Priority Track Marker on the track and open its properties window.

Click the label Priority 2 to select one of level 1, 2 (the default selection), or 3.

These priority values have no set meanings but can be assigned to specific trains to force them through the selected section of track (the track sections are defined as between consecutive junction point sets).

Assigning Priority Levels to Trains

Each locomotive can be assigned a priority level of 1, 2 or 3. Priority 2 is the default level. Again, these values have no set meanings beyond what you decide they will mean.

For example you could assign priority 1 to express trains and 3 to slow general freight stopping trains.

Priority Operation

DotPoint.JPG Priority Track Markers only work on AI controlled trains. They have no effect on manually controlled trains
DotPoint.JPG Priority Track Markers "fool" an AI train that has been set to the same priority level into "thinking" that the path containing the marker is the shortest possible path, even when it is not
DotPoint.JPG If the priority level of the AI train does not match the priority level of a track marker, then the AI will select the shortest available path which may be the one containing the priority marker
DotPoint.JPG If the specified path is blocked, then the AI will ignore the Priority Track Marker and find another path
