How to Use Track Markers

The information in this Wiki Page applies to both TANE and TRS19.

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 a Track Marker faces has NO effect on its operation

Adding a Track Marker

Notes: A Track Marker has just one property, its Trigger Radius (the red "wings" shown in the image below). The radius value (in metres) is shown below the marker name. This controls how close an AI controlled train has to approach the marker

Steps: Open the Track Tool Select the Trackmark button Select the Track Marker Select the + (add) button - it may already be selected 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 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 Action Radius of an existing Track Marker Click the Get Trigger Radius icon Click the Track Marker whose radius you want to copy - the radius will be copied into the Trigger Radius value box 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 above) to another Track Marker Click the Set Trigger Radius icon 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 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)

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 in the Trainz Wiki 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

	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 both TANE and TRS19
	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 both TANE and TRS19
	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.
