BlueDot10x10.png Track Direction Marks are yellow coloured markers that are invisible in Driver but visible in Surveyor
BlueDot10x10.png They are "One Way" signs that force trains under AI control to travel in a specific direction through the track section where they are placed
BlueDot10x10.png They only work on AI controlled trains and have no effect on manually controlled trains

What are Track Direction Marks?

While Track Marks can be used to direct trains around a layout, they must be added to the Driver Commands in the form of Drive Via commands, and similar, to individual train drivers to work. Direction Marks can perform some of the same work without needing to be added to the command lists of the drivers. Their disadvantage is that Direction Marks will affect all AI controlled trains while Track Marks will only affect those AI trains where they appear in the driver command lists.
Direction Marks force AI drivers to follow a particular path. They only work on AI controlled trains and have no effect on manually controlled trains.


Route or Session?

BlueDot10x10.png Direction Marks can be placed in a Route Layer or in a Session Layer


NotePad.PNG Notes:

DotPoint.JPG Placing Direction Marks in a Route layer (e.g. in the same layer as the track) means that they will be available in all Sessions created using that particular Route.
DotPoint.JPG Placing Direction Marks in a Session layer means that they will only be available in that particular Session. This can be useful if two or more Sessions are being created and you want to use different Direction Marks in each Session.

Adding a Track Direction Mark

NotePad.PNG Notes:

A Direction Mark has no useful properties other than the direction it is pointing. This is the direction that all AI controlled trains will be forced to take.

PencilTips.PNG The name of a Direction Mark has NO EFFECT on its operation but can be useful for locating it in a route


In Surveyor Classic (S10)

Set its Trigger Radius (S20)

The Trigger Radius sets the green "effect radius" of the marker. It has no effect on its operation but allows you to keep its "visibility" clear of other track objects such as junctions and other markers.


DirectionmarkRadius S20.png
Steps: To adjust the trigger radius of a Direction Mark:-
DotPoint6Blue.png Left Click and Drag Forward or Backward on the Green Dot next to the Track Mark to increase or reduce its Trigger Radius


Move the Direction Mark Along the Track(S20)

Direction Marks can be moved along the track or to other tracks.

DirectionmarkMove S20.png
Steps: To move the Direction Mark:-
DotPoint7Blue.png Left Click and Drag Forward or Backward on the Yellow Dot next to the Direction Mark to move it along the track or to another track


Move the Direction Mark Vertically (S20)

Direction Marks can be physically placed above (or below) the track. This feature allows them to be placed, for example, above the track so that they will not be hidden in Surveyor if a consist is parked on a marker.
DirectionmarkFineAdjustVertical S20.png
Steps: To move a Direction Mark vertically:-
NotePad.PNG This option is only available with the Fine Adjustment Tool - the  D  key
DotPoint8Blue.png Left Click and Drag Forward or Backward on the  Blue  Vertical Axis Line above the Direction Mark to it up or down
PencilTips.PNG If you need to return the Direction Mark to its original position then:-
Steps: To correctly reattach the Direction Mark to the track:-
DotPoint1.JPG select the object and open (Left Click on) its Context Menu Icon (or press the  T  key)
DotPoint2.JPG from the popup menu select  Reattach to Track 

Move the Direction Mark Horizontally (S20)

Direction Marks can be physically placed left or right alongside the track. This feature allows them to be placed, for example, beside the track so that they will not be hidden in Surveyor if a consist is parked on a marker.
DirectionmarkFineAdjustHorizontal S20.png
Steps: To move a Direction Mark horizontally:-
NotePad.PNG This option is only available with the Fine Adjustment Tool - the  D  key
DotPoint9Blue.png Left Click and Drag Forward or Backward on the  Red  Horizontal Axis Line attached to the Direction Mark to move it left or right
DotPoint10Blue.png Left Click and Drag Forward or Backward on the  Green  Horizontal Axis Line attached to the Direction Mark to move it forward or back
PencilTips.PNG If you need to return the Track Mark to its original position then:-
Steps: To correctly reattach the Track Mark to the track:-
DotPoint1.JPG select the object and open (Left Click on) its Context Menu Icon (or press the  T  key)
DotPoint2.JPG from the popup menu select  Reattach to Track 


NotePad.PNG Notes:

The  Green  Horizontal Axis Line shown as DotPoint10Blue.png in the image pointing forward from the Track Mark will move the Track Mark forward/backward regardless of whether it is on the track or not. It has the same effect as DotPoint7Blue.png Move a Track Mark Along the Track. However, by using this tool it is possible to move the Track Mark beyond the end of the track if that is ever required.


Assign a Direction Mark to Another Layer (S20)

The Info Palette will show the layer assigned to the currently selected object. To the left of the layer name is a small arrowhead object.
Info palette

Layer control
Steps: To assign a Direction Mark to a layer:-
In the Info Palette:-
DotPoint1.JPG Left Click the small arrowhead next to the layer name. This will open the layer properties for the selected object
DotPoint2.JPG Left Click the Layer drop down box to select a new layer for the object
DotPoint3.JPG if required, Left Click the Binding drop down box to select a new binding layer for the object. It cannot be bound to its own layer
DotPoint4.JPG if required, Left Click the  Lock Layer  button to lock the selected layer. If the layer is already locked then this will be shown as an  Unlock Layer  button


Stop.PNG WARNING:
DotPoint.JPG You will not be allowed to place a track object in a layer that is higher up the list than the layer containing the track
DotPoint.JPG Moving an object from one layer group to another (e.g. from the Route Layer Group to the Session Layer Group) will change where the object is saved (in the Route or in the Session)

Direction Mark Operation

BlueDot10x10.png Track Direction Marks only work on AI controlled trains. They have no effect on manually controlled trains
BlueDot10x10.png If the set path is blocked, then the AI will NOT attempt to find another path
BlueDot10x10.png A set path will be ignored if a shorter path is available


Consider the situation represented in the diagrams below. An AI controlled train is moving left to right towards a junction and a loop line. A Direction Mark (yellow triangle) has been set on the main line which only allows AI trains traveling right-to-left to pass along that section of track.


In Figure 1 below, The train approaches the junction at the start of the one way section.


Direction Map - approach
Figure 1


In Figure 2 below, the train has been forced to take the loop line to avoid the section controlled by the Direction Mark.


Direction Map - bypass
Figure 2


In Figure 3 below, the loop line has been blocked by another train. The moving train will attempt to use the loop line but it will be halted and will not attempt to find another path.


Direction Map - blocked
Figure 3


Direction Marks can be ignored by the AI
In Figure 4 below, the marker has been placed on the loop line and is pointing in the same direction as the moving train. However, the mainline path represents the shorter route for the consist so the "preferred" direction, as indicated by the Direction Mark, is ignored. Placing a Direction Mark is no guarantee that the path will be followed if more suitable paths are available.
