The information in this Wiki Page applies to TANE, TRS19, Trainz Plus and TRS22.

	Track Marks 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

[edit] What are Track Marks?

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

Track Marks are the targets for:-
	destinations using Drive To Trackmark and Navigate To Trackmark driver commands
	waypoints using Drive Via Trackmark and Navigate Via Trackmark driver commands
They can also be used to:-
	hold Navigation Points
	set locations for Coupling operations

[edit] Route or Session?

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

Notes:

	Placing Track Marks 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
	Placing Track Marks 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 Marks (destinations and waypoints) in each Session.

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

How to Use Layers

[edit] Adding a Track Mark

Notes:

A Track Mark has two important properties:-

	its name which is needed for all commands and rules that use the Track Mark, and
	its Trigger Effect Radius (the red "wings" shown in the image below, the radius value is shown below the Track Mark name). This controls how closely an AI train has to approach the marker (smaller radius = closer to the Track Mark)

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

[edit] In Surveyor Classic (S10)

[edit] Adding a Track Mark (S10)

Steps: To add a trackmark:-
	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 Mark is to be placed
If necessary, you can adjust the position of the Track Mark 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 Mark has been placed its properties window will appear. You can:-

	Enter a Name for the Track Mark, and
	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 Mark - 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")

[edit] Set the Track Mark Effect Radius (S10)

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". The smaller the radius the closer it must approach.

Other track objects that have a Trigger Effect Radius include Track Direction Markers, Track Priority Markers, Track Triggers and Whistle Signs. In some cases the visible "effect wings" are green instead of red.

Steps: To set a Track Mark 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 Mark

	Left Click the Get Effect Radius icon
	Left Click on the Track Mark 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 Mark

	Left Click the Copy Radius Value icon
	Left Click on the Track Mark 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 Mark
	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 Mark as the mouse moves (but only one Track Mark at a time)

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

shown above

[edit] In Surveyor 2.0 (S20)

Surveyor 2.0 is only available in Trainz Plus and TRS22 Platinum

[edit] Adding a Track Mark (S20)

In the Filter Palette either:-

Left Click on the Track Objects icon

FilterPaletteTrackObjectsSelected S20.png

OR

Left Click on the Content Drop Down Box

FilterPaletteNoIconSelected S20.png
Then select Track Objects
FilterSelectTrackObjects S20.png

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 Mark - you may have to scroll down the list to find the asset.

AssetPaletteSearchMarkScrolled S20.png
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 Mark on the track.

Steps: To add a Track Mark:-
	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 Mark
Once placed a Track Mark can be easily moved if needed.

Notes:

To delete a Track Mark (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 Mark

press the Delete key

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

Steps:
	select the Track Mark then Left Click on its Context Menu Icon (or press the T key)
	from the popup menu select the Rotate Trackside option

Note: the direction it faces has no effect on its operation

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

[edit] Change the Track Mark Name (S20)

The Track Mark name is used to identify it for Drive and other commands.

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

[edit] Set its Effect Radius (S20)

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". The smaller the radius the closer it must approach.

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

Left Click and Drag Forward or Backward on the Green Dot next to the Track Mark to increase or reduce its Trigger Radius

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 a Trigger Effect Radius include Track Direction Markers, Track Priority Markers, Track Triggers and Whistle Signs. In some cases the visible "effect wings" are green instead of red.

Once you have set the Name and Effect Radius of a track mark it can be quickly duplicated (cloned) in Surveyor 2.0 with those settings and moved to a new location. You can easily edit the clones name at the new location.
See

How to Use S20 Tools - Cloning Objects for the details

[edit] Move the Track Mark Along the Track (S20)

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

Steps: To move the Track Mark:-
	Left Click and Drag Forward or Backward on the Yellow Dot next to the Track Mark to move it along the track or to another track

The yellow dot beneath the Track Mark, labelled as in the image, is the Attachment Point for the Track Mark. This is where it is attached to the track and is its Active Point, the target of Drive To Trackmark and Navigate to Trackmark commands.

The attachment point is always on the track but the Track Mark object itself, the visible 3D arrow head, does not have to be physically on the track.

[edit] Move the Track Mark Vertically (S20)

Track 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.

Steps: To move a Track 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

Because the Attachment Point of the Track Mark, the yellow dot, remains on the track, moving the track mark object vertically does not affect its operation.

[edit] Move the Track Mark Horizontally (S20)

Track 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.

Steps: To move a Track 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 Track Mark to move it left or right

Left Click and Drag Forward or Backward on the Green Horizontal Axis Line attached to the Track 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

Because the Attachment Point of the Track Mark, the yellow dot, remains on the track, moving the track mark object horizontally does not affect its operation.

Notes:

The Green Horizontal Axis Line shown as

in the image pointing forward from the Track Mark will move it forward/backward regardless of whether it is on the track or not. It has the same effect as

Move a Track Mark Along the Track without moving its attachment point. Using this tool makes it possible to move the Track Mark visible object beyond the end of the track if that is ever required. This will have no effect on its operation.

[edit] Assign a Track 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.

Steps: To assign a Track Mark 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:

	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
	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

[edit] Track Mark Operation

The most common use for Track Marks 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.

[edit] Driver Navigation Commands

Information on adding driver commands can be found at:-

How to Use the Driver Setup Rule

	Notes:
	Drive To Trackmark and Drive Via Trackmark commands will NOT force the AI to find an alternative clear path to the Track Mark if the shortest path is blocked
	Navigate To Trackmark and Navigate Via Trackmark commands will force the AI to find an alternative clear path to the Track Mark if the shortest path is blocked. The path chosen may not be prototypical

	Drive To Trackmark Instructs the AI driver to Drive, via the shortest available path, to the designated Track Mark. The AI will noticeably slow the train as it approaches the Track Mark. Switches ahead of the train that are not locked against the AI will be set to allow the train to proceed and reset after the train has cleared the switch. The AI driver will NOT attempt to find a way around blockages when calculating the shortest path to the Track Mark. All signals and speed signs along the route are obeyed. This command is built in to Trainz
	Drive Via Trackmark Instructs the AI driver to Drive, via the shortest available path, to and through the designated Track Mark. If there are no further navigation commands (e.g. Drive To, etc) then the AI will halt the train after passing the Track Mark. If there are further navigation commands then the AI will proceed through the Track Mark to the next Track Mark or Industry at normal speed. Switches ahead of the train that are not locked against the AI will be set to allow the train to proceed and reset after the train has cleared the switch. The AI driver will NOT attempt to find a way around blockages when calculating the shortest path to the Track Mark. All signals and speed signs along the route are obeyed. This command is built in to Trainz
	Navigate To Trackmark Instructs the AI driver to Drive, via the shortest available path, to the designated Track Mark. The AI will noticeably slow the train as it approaches the Track Mark. Switches ahead of the train that are not locked against the AI will be set to allow the train to proceed and reset after the train has cleared the switch. The AI driver will attempt to find a way around blockages when calculating the shortest path to the Track Mark. All signals and speed signs along the route are obeyed. This command is built in to Trainz
	Navigate Via Trackmark Instructs the AI driver to Drive, via the shortest available path, to and through the designated Track Mark. If there are no further navigation commands (e.g. Navigate To, etc) then the AI will halt the train after passing the Track Mark. If there are further navigation commands then the AI will proceed through the Track Mark to the next Track Mark or Industry at normal speed. Switches ahead of the train that are not locked against the AI will be set to allow the train to proceed and reset after the train has cleared the switch. The AI driver will attempt to find a way around blockages when calculating the shortest path to the Track Mark. All signals and speed signs along the route are obeyed. This command is built in to Trainz

[edit] Navigation Points

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

Information on navigation points can be found at:-

How to Use Navigation Points

[edit] Coupling Operations

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

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 trackmark. More information on this command can be found at

Couple At Trackmark

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

Information on adding driver commands can be found at:-
