How to Use Track Markers

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

In Summary: Track Markers are red coloured track objects that are invisible in Driver Mode but visible in Surveyor Mode Track Markers are used as destinations or waypoints for AI driver commands Track Markers only work on AI controlled trains. They have no effect on manually controlled trains The direction that the marker is pointing has absolutely NO EFFECT on its 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 Mode.

Track markers are the targets for:-

• Drive To Trackmark and Navigate To Trackmark driver commands
• Drive Via Trackmark and Navigate Via Trackmark driver commands

They can also be used as:-

• attachments for Navigation Points
• locations for Coupling operations

Route or Session?

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

Notes: Placing Track Markers 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 Track Markers in a Session layer means that they will only be available in that 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

Adding a Track Marker

Notes: A Track Marker has two important properties:- its name which is needed for all commands and rules that use the Track Marker, and its Trigger Radius (the red "wings" shown in the image below, the radius value is shown below the marker name). This controls how closely an AI train has to approach the marker to activate it (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)

 Setting the Track Marker 

Steps: Open the Track Tool Select the Trackmark button Select the Track Marker Select the + (add) button - it may already be selected 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 When placed, the properties window for the Track Marker will appear. Enter a name for the Track Marker and, if needed, select a layer.

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

 Set the Trigger Radius 
At the bottom of the Track Tools flyout menu is an Advanced button. Left click this button to open the Track Marker advanced tool set.

Steps: Left click the Advanced button You then have a choice of methods to set and adjust the Trigger Radius of Track Markers To copy the current Trigger Radius of an existing Track Marker Left click the Get Trigger Radius icon Left click the Track Marker whose radius you want to copy - the radius will be copied into the Trigger Radius value box (the default value is 20.00 metres) To manually alter the Trigger Radius Type the new value (in metres) into the Trigger Radius value box To apply a value in the Trigger Radius value box (from methods , or ) to another Track Marker Left click the Set Trigger Radius icon Left click on the Track Marker that is to receive the new value (you can click on more than one) To adjust the value up or down Left click the Adjust Trigger Radius button Select the Track Marker Hold down the Left mouse button and move the mouse forward (to increase the value) or backwards (to reduce the value) The new value will be immediately applied to the selected Track Marker as the mouse moves (but only one marker at a time)

Once you have a Trigger 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)

 Adding a Track Marker 

In the Asset Palette either:-

Left click the Track Mesh Filter icon

OR

Left click the Content Drop-down Box Then select Track Objects

Shortcut  If you already have a Track Mark in your route then:- select the Eyedropper Tool in the Tools Palette (or press the  R  key) Left click on the existing Track Mark object This will instantly select the Track Mark in the filter list. Jump straight down to Step below.

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

This will list all the Track Objects containing the text "mark" in the filter list. Select the item Track Mark. If you are not sure about an asset then double-click on the name to bring up its image and description.

Place the Track Mark on the track.

Notes: To delete a Track Mark (or any asset):- 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:- Left click on its Context Tool (or press the  T  key if the asset has already been selected) from the popup menu select Rotate Trackside But note that the direction it faces has no effect on its operation.

Steps: Select the Placement Tool (or press the  E  key) from the Tools Palette Left click on the track at the position where you want to place the Track Mark The Track Mark can be easily moved if needed - see below.

 Set the Track Mark Properties 

Name the Track Mark Steps: Left click on the Context Tool ( in the image on the left or press the  T  key) to open up the object property and control menu Left click on Edit Properties Enter a name for the Track Mark

Set the Track Mark Trigger Radius

	Steps: Left click and hold down the mouse button on the Green Dot next to the Track Mark ( in the image above) While holding down the Left mouse button, move the mouse Forward or Backward to increase or reduce the trigger radius

Move the Track Mark Along the Track

	Steps: Left click and hold down the mouse button on the Yellow Dot next to the Track Mark ( in the image above) While holding down the Left mouse button, move the mouse Forward or Backward to drag the Track Mark along the track

Reposition the Track Mark Up/Down Steps: Select the Fine Adjustment Tool (or press the  D  key) Left click and hold down the mouse button on the Blue Vertical Axis Line above the Track Mark ( in the image on the left) While holding down the Left mouse button, move the mouse Forward or Backward to move the Track Mark Up or Down This feature allows a Track Mark to be placed above the track so that it will not be hidden if a consist is parked on the Track Mark If you need to return the Track Mark to its original position then:- Left click on its Context Tool (or press the  T  key if the asset has already been selected) from the popup menu select Reattach to Track

Reposition the Track Mark Left/Right

	Steps: Select the Fine Adjustment Tool (or press the  D  key) Left click and hold down the mouse button on the Red Horizontal Axis Line on the Track Mark ( in the image above) While holding down the Left mouse button, move the mouse Forward or Backward to move the Track Mark Left or Right of the track This feature allows a Track Mark to be placed alongside the track so that it will not be hidden if a consist is parked on the Track Mark

If you need to return the Track Mark to its original position then:- Left click on its Context Tool (or press the  T  key if the asset has already been selected) from the popup menu select Reattach to Track

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

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

Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Drive To Trackmark Instructs the AI driver to Drive, via the shortest available path, to the designated Track Marker. The AI will noticeably slow the train as it approaches the Track Marker. 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 Marker. All signals and speed signs along the route are obeyed. This command is built in to Trainz
Error creating thumbnail: /bin/bash: line 1: /usr/bin/convert: No such file or directory Error code: 127	Drive Via Trackmark Instructs the AI driver to Drive, via the shortest available path, to and through the designated Track Marker. If there are no further navigation commands (e.g. Drive To, etc) then the AI will halt the train after passing the Track Marker. If there are further navigation commands then the AI will proceed through the Track Marker to the next Track Marker 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 Marker. All signals and speed signs along the route are obeyed. This command is built in to Trainz

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 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
