The information in this Wiki Page describes how to install, configure and use Track Markers in T:ANE, TRS19, TRS22 and Trainz Plus.

	Track Markers are red coloured track objects that are invisible in Driver but visible in Surveyor
	They are used as destinations or waypoints for AI driver commands
	They only work on AI controlled trains and have no effect on manually controlled trains
	The direction that the markers point has absolutely NO EFFECT on their operation

What are Track Markers?

The Trainz AI relies heavily on Track Markers to direct trains around a layout. They are only visible in Surveyor

Track Markers are the targets for:-
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	destinations using Drive To Trackmark and Navigate To Trackmark driver commands
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	waypoints using Drive Via Trackmark and Navigate Via Trackmark driver commands
They can also be used to:-
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	hold Navigation Points
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	set locations for Coupling operations

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127

Route or Session?

Track Markers can be placed in a Route Layer or in a Session Layer

The answer to this question could be important if you are creating two or more sessions for the same route.

Notes:

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Placing Track Markers in a Route layer (e.g. in the same layer as the track) will save them with the Route and they will be available in all Sessions created using that particular Route
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Placing Track Markers in a Session layer will save them with the Session and 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 Track Markers (destinations and waypoints) in each Session.

Information on Route and Session layers can be found at:-

How to Use Layers

Adding a Track Marker

Notes:

A Track Marker has two important properties:-

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	its name which is needed for all commands and rules that use the Track Marker, and
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	its Effect Radius (the red "wings" shown in the image below, the radius value is shown below the Track Marker name). This controls how closely an AI train has to approach the marker (smaller radius = closer to the Track Marker)

The direction that a Track Marker is pointing has NO EFFECT on its operation

In Surveyor Classic (S10)

Adding a Track Marker (S10)

Track Markers are Track Objects and have to be attached to a track segment.

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127

Steps: To add a Track Marker:-
	Open the Tracks Tool Flyout or press the F4 key
	Left Click on the Trackmark button or press the V key
	Left Click the item named Track 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 Marker is to be placed
If necessary, you can adjust the position of the Track Marker by dragging it along the track using the Move tool

Avoid placing a Track Marker on a junction. You could accidentally place the marker on the wrong junction branch which could result in AI trains being directed along the wrong path

Immediately after the Track Marker has been placed its properties window will appear. You can:-

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Enter a Name for the Track Marker, and
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	if needed, select a Layer and a Bound Layer - see the Trainz Wiki Page How to Use layers for the details

Enter a useful name for each Track Marker - the name will be needed for driver commands and session rules. Many creators base the name on the location (e.g. "Maintown Track 1 North")

Change its Direction (S10)

The direction the marker is pointing has no effect on its operation.

If you need to change the direction of a Track Marker then:-

Steps: To Reverse the Direction of a Track Marker:-

	In the Track Tools Flyout (the F4 key) select Trackmark Mode (the V key)
	Then select the Rotate Trackmark Tool (the R key)
	Left Click on the Track Marker

Set its Effect Radius (S10)

The Effect Radius sets how close a consist has to approach the marker to activate or complete its operation. The default value is 20m.

The methods described below are NOT available in Surveyor Classic (S10) in versions of Trainz that have the Surveyor 2.0 (S20) interface as an option (TRS22PE and Trainz Plus). For these versions switch to Surveyor 2.0 and use the methods described in the

Set its Effect Radius (S20) section below.

At the bottom of the Track Tools flyout menu is an Advanced button. Left Click this button to open the advanced tools.

The Effect Radius is the size of red "effect wings" attached to both ends of the marker. This sets how close a consist has to approach the marker to complete certain driver commands such as Drive To Trackmark or to activate any Navigation Point attached to the marker. The smaller the radius the closer it must approach.

Other Track Objects that have an Effect Radius include:-

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Track Triggers
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Direction Markers
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Priority Markers

Steps: To set a Track Marker Effect Radius:-

In the Track Tools flyout, Left Click on the Advanced button to open the Radius tools and properties. You will have a choice of 4 methods to set and adjust the Effect Radius

Options: Choose one of:-

To copy the Effect Radius of an existing Track Marker

	Left Click the Get Effect Radius icon
	Left Click on the Track Marker whose radius you want to copy - the radius will be copied into the Effect Radius Value text box (the default value is 20.00 metres)
	To apply the new value see option below

To manually alter the Effect Radius value

	Type the new value (in metres) into the Effect Radius Value text box
	To apply the new value see option below

To apply a value in the Effect Radius Value text box (from methods

,

or

) to another Track Marker

	Left Click the Copy Radius Value icon
	Left Click on the Track Marker that is to receive the new value (you can click on more than one)

To adjust the Effect Radius value up or down

	Left Click the Adjust Effect Radius button
	Select the Track Marker
	Left Click and Drag Forward (to increase the value) or Backward (to reduce the value)
	The new value will be immediately applied to the selected Track Marker as the mouse moves (but only one Track Marker at a time)

Once you have an Effect Radius entered in the value box, you can apply it to any number of Track Markers by using method

shown above

In Surveyor 2.0 (S20)

Surveyor 2.0 is only available in Trainz Plus and TRS22 Platinum

Adding a Track Marker (S20)

Track Markers are Track Objects and have to be attached to a track segment. The Track Marker object can be moved off the track (left, right, above, below) but its attachment point is always connected to a track segment.

Steps: To add a Track Marker:-

In the Filter Palette either:-

Left Click on the Track Objects icon

OR

Left Click on the Content Drop Down Box

Then select Track Objects

Shortcut If you already have a Track Marker placed in your route then:-
	move the tool pointer over the existing track marker object and hold down the Alt key. The object name will appear in a ToolTip attached to the pointer
	while holding down the Alt key Left Click on the track marker to identify it in the Assets Palette and to select the Placement Tool. Release the key.
Jump to Step below.

Notes:

If the Filter Palette and the Assets Palette are not shown on the screen, then:-

Steps: To display palettes:-

open the

Window Menu from the menu icons at the top of the screen

	visible palettes have ticks next to their names
	invisible (hidden) palettes have no ticks next to their names

if any required palette does not have a tick next to its name then Left Click on the name of the palette or on the empty

box next to its name. This will add a

and make the palette visible

There is a Trainz Wiki Page specifically covering the S20 Palettes at
How to Use the Surveyor 2.0 Palettes

In the Assets Palette to narrow down the filter list, type "mark" (UPPER/lower case does not matter) in the Search Text Box

Both pallets shown docked

This will list all the Track Objects containing the text "mark" in their names or descriptions.

Left Click on the item name Track Marker - you may have to scroll down the list to find the asset.

If you are not sure about an asset then Double Left Click on the name to bring up its image and description.

When you select any asset in the Assets Palette list it will automatically select the Placement Tool so the next Left Click in your Trainz World will add that asset to your Trainz World

Place the Track Marker on the track.

Steps: To add a Track Marker:-
	If, for some reason, the Placement Tool has not been selected then Left Click on the Placement Tool or press the E key
	Left Click on the track at the position where you want to place the Track Marker
Once placed a Track Marker can be easily moved if needed.

Avoid placing a Track Marker on a junction. You could accidentally place the marker on the wrong junction branch which could result in AI trains being directed along the wrong path

Notes:

To delete a Track Marker (or any asset):-

Steps:

select either the:-

	Free Move Tool (or press S ) OR
	Fine Adjustment Tool (or press D )

Left Click on the Track Marker

press the Delete key

Once you have added a Track Marker and set any of its properties (Name and Effect Radius - see the following sections) it can be quickly duplicated (Cloned) in Surveyor 2.0 with those settings and moved to a new location. You can then easily edit the name and properties of the clone at the new location. See

How to Use S20 Tools - Cloning Objects for the details

Change its Direction (S20)

The direction a Track Marker is pointing has no effect on its operation.

If you need to rotate a Track Marker to face the opposite direction then:-

Steps: to reverse the direction of a Track Marker:-
	select the Track Marker then Left Click on its Context Menu Icon (or press the T key)
	from the popup menu select the Rotate Trackside option

Change its Name (S20)

The name of a Track Marker is used to identify it for Driver Commands (Drive To Trackmark, Navigate To Trackmark, etc) and other operations (e.g. Navigation Points).

Track Markers can be renamed to give them a more recognisable identity (e.g. ""East Branch Down" instead of "Trackmark 4606").

Steps: To change the name of a Track Marker:-
	using either the Free Move Tool or the Fine Adjustment Tool select (Left Click on) the Track Marker to be renamed
	in the Info Palette (you may need to make this palette visible - see the Notes: for Adding a Track Marker - Step 1 above) Left Click in the Name: entry box. Enter a name for the Track Marker and press the Enter key

Track Markers used for Driver Commands, Navigation Points or other session operations MUST be given unique names.

Set its Effect Radius (S20)

The Effect Radius sets how close a consist has to approach the marker to activate or complete its operation. The default value is 20m.

The Effect Radius is the size of red "effect wings" attached to both ends of the marker. This sets how close a consist has to approach the marker to complete certain driver commands such as Drive To Trackmark or to activate any Navigation Point attached to the marker. The smaller the radius the closer it must approach.

In the image shown below, the approaching vehicle will "reach" the Track Marker when it is 20m away from it.

Steps: To adjust the effect radius of a Track Marker:-

Left Click and Drag on the

Green Dot next to the Track Marker.

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Drag it Left or Right (at 90° to the direction of the track) to change its Effect Radius.
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	The speed at which you drag it will set the speed at which the radius value will change - faster movements will give larger value changes.

For the best results when adjusting the Effect Radius of any track object, move your camera POV (point of view) to directly above the object

Other Track Objects that have an Effect Radius include:-

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Track Triggers
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Direction Markers
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Priority Markers

Move it Along the Track (S20)

Track Markers can be moved along the track or to other tracks.

Steps: To move the Track Marker:-
	Left Click and Drag Forward or Backward on the Yellow Dot, its Attachment Point, next to the Track Marker or drag the object itself (see Notes: below), to move it along the track or to another track

Notes:

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	If you drag the object itself and not its Attachment Point then it will stay at its original height as it is moved along the track. If the track is on a grade then the object will rise above or fall below the track as it is moved. To return the object to its correct height on the track see the next section Move the Track Marker Vertically below.
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Dragging it by the attachment point will force it to stay at the height of the track as it is moved.

Move it Vertically (S20)

Track Markers can be physically placed above or below the track.

This feature allow a marker to be placed, for example, above the track so that it will not be hidden in Surveyor if a consist is parked on the marker. A change in height will have no effect on its operation.

Steps:

To move a Track Marker vertically choose option

OR

:-

	Using the Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127 Fine Adjustment Tool (press the D key) Left Click and Drag Forward or Backward on the Blue Vertical Axis Line (labelled as in the image) to move it up or down OR
	In the Info Palette enter a value in the Height setting and press the Enter key. NOTE: the height is measured from the absolute 0m level and not from the current height of the object or the track.

If you need to return the Track Marker to its original height then:-

Steps: To correctly reattach the Track Marker 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 it Horizontally (S20)

Track Markers can be physically placed left or right of the track.

This feature allow a marker to be placed so that it will not be hidden in Surveyor if a consist is parked on the marker. A change in position left or right will have no effect on its operation.

Steps: To move a Track Marker horizontally:-

Track Objects can be moved along the track using the methods shown in the section

Move the Track Marker Along the Track above.
The two methods described below only work if the Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127 Fine Adjustment Tool - the D key - is selected.

Left Click and Drag Forward or Backward on the Red Horizontal Axis Line attached to the Track Marker to move it left or right of the track

Left Click and Drag Forward or Backward on the Green Horizontal Axis Line attached to the Track Marker to move it forward or back in a straight line that will ignore any curves in the track

If you need to return the Track Marker to its original position then:-

Steps: To correctly reattach the Track Marker 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 it 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.

Steps: To assign a Track Marker to a layer:-
In the Info Palette:-
	Left Click the small arrowhead next to the layer name. This will open the layer properties for the selected object
	Left Click the Layer drop down box to select a new layer for the object
	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
	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

WARNING:

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	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
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	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)

Information on layers can be found at:-

How to Use Layers

Track Marker Operation

The most common use for Track Markers is as destinations for driver commands or as "way points" to direct a train to a destination via one or more intermediate places. They can also be used as the targets for Navigation Points and coupling operations.

Driver Navigation Commands

Information on adding driver commands can be found at:-

How to Use the Driver Setup Rule

Navigation Points

Navigation Points can be attached to Track Markers to provide users with session instructions.

Information on navigation points can be found at:-

How to Use Navigation Points

Coupling Operations

An AI controlled train can be issued with a driver command to couple with the consist located at a specified Track Marker.

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127

The AI driver moves the train (or just the locomotive if it is by itself) to couple with the wagon that is closest to a specified Track Marker. More information on this command can be found at

Couple At Trackmark

This command must be downloaded from the DLS and installed in Trainz
