What are Track Markers?

In Summary:
Track Markers are red coloured track objects that are invisible in Driver Mode but visible in Surveyor Mode. They 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


Trainz relies heavily on Track Markers to direct trains around a layout under the control of the AI system.

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:-

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 close an AI controlled train has to approach the marker


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

Steps:
  1. Open the Track Tool
  2. Select the Trackmark button
  3. Select the Track Marker
  4. Select the + (add) button - it may already be selected
  5. Click on the track location where the Track Marker is to be placed

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")


Setting the Trigger Radius

At the bottom of the Track Tools flyout menu is an Advanced button. Click this button to open the Track Marker advanced tool set.
Steps:
  • 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

  1. Click the Get Trigger Radius icon
  2. 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

  1. Click the Set Trigger Radius icon
  2. 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

  1. Click the Adjust Trigger Radius button
  2. Select the Track Marker
  3. Hold down the left mouse button and move the mouse forward (to increase the value) or backwards (to reduce the value)
  4. 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

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:-


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

If there are no further navigation commands (e.g. Navigate To, etc) then the AI will halt the train after passing the Track Marker.

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

Information on navigation points can be found at:-


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
