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?
|
Direction Marks can be placed in a Route Layer or in a Session Layer |
|
Notes:
|
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.
|
|
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
|
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.
|
|
In Surveyor Classic (S10)
|
Steps: To add a Track Direction Mark:- |
|
Open the Track Tool flyout or press the F4 key |
|
Left Click on the Trackmark button or press the V key |
|
Left Click the item named Track Direction Marker in the asset list |
|
Left Click the + Add button - it may already be selected - or press the A key |
|
Left Click on the track location where the Track Mark is to be placed |
|
if it is not facing the right direction then Left Click on the Rotate Trackmark button or press the R key |
If necessary, you can adjust the position of the marker by dragging it along the track using the Move tool |
|
|
In Surveyor 2.0 (S20)
Surveyor 2.0 is currently only available in Trainz Plus and TRS22 Platinum.
Adding a Direction Mark (S20)
In the Asset Palette either:-
Left Click on the Track Mesh Filter icon
|
|
OR |
|
|
Shortcut
If you already have a Direction Mark placed in your route then:- |
|
move the tool pointer over the existing direction marker object and hold down the Alt key. The object name will appear in a ToolTip attached to the pointer |
|
Alt + Left Click (hold down the Alt key and Left Click) on the direction marker to identify it in the Assets Palette and to select the Placement Tool. Release the key. |
Jump to Step below. |
|
To narrow down the filter list, type "mark" (UPPER/lower case does not matter) in the Search Text Box
Place the Direction Mark on the track.
|
|
Notes:
|
|
To add a direction mark, or any object, you will need to select the Placement Tool |
|
To edit a direction mark once it has been placed you will usually use either the Free Move Tool or the Fine Adjustment Tool |
|
|
|
Set the Marker Direction
The direction that the marker points is its ONLY important property.
|
Steps: To reverse its direction:- |
|
Left Click on its Context Menu Icon (or press the T key if the object has already been selected). From the popup Context Menu select Rotate Trackside |
|
|
Change its Name
The name of the marker is only useful for finding it in the route. It is not needed for any operational purpose.
|
Steps: To change the name of a Direction Mark:- |
|
using either the Free Move Tool or the Fine Adjustment Tool select (Left Click on) the Direction Mark to be renamed |
|
in the Info Palette (you may need to make this palette visible - see the Notes: for Step 1 above) Left Click in the Name: entry box. Enter a name for the Track Mark and press the Enter key |
|
|
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. |
|
Steps: To adjust the trigger radius of a Direction Mark:- |
|
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.
|
Steps: To move the Direction Mark:- |
|
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)
Track Marks can be physically placed above (or below) the track.
|
Steps: To move a Direction Mark vertically:- |
|
This option is only available with the Fine Adjustment Tool - the D key |
|
|
Left Click and Drag Forward or Backward on the Blue Vertical Axis Line above the Track Mark to it up or down |
|
If you need to return the Track Mark to its original position then:-
Steps: To correctly reattach the Track Mark to the track:- |
|
select the object and open (Left Click on) its Context Menu Icon (or press the T key) |
|
from the popup menu select Reattach to Track |
|
|
|
|
Move the Direction Mark Horizontally (S20)
Directin Marks can be physically placed left or right alongside the track.
|
Steps: To move a Direction Mark horizontally:- |
|
This option is only available with the Fine Adjustment Tool - the D key |
|
|
Left Click and Drag Forward or Backward on the Red Horizontal Axis Line attached to the Direction Mark to move it left or right |
|
Left Click and Drag Forward or Backward on the Green Horizontal Axis Line attached to the Direction Mark to move it forward or back |
|
If you need to return the Track Mark to its original position then:-
Steps: To correctly reattach the Track Mark to the track:- |
|
select the object and open (Left Click on) its Context Menu Icon (or press the T key) |
|
from the popup menu select Reattach to Track |
|
|
|
|
Assign a Direction Mark to Another Layer (S20)
Direction Mark Operation
|
Track Direction Marks only work on AI controlled trains. They have no effect on manually controlled trains |
|
If the set path is blocked, then the AI will NOT attempt to find another path |
|
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. |
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. |
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. |
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. |
