Display Custom HUD Rule
This rule shows or hides a HUD panel displaying additional information about the selected train. Once started this rule completes immediately without running any child rules.
The information displayed by the Custom HUD is as follows:
Next Limit
Next posted speed limit (if any) and distance to it.
Next Signal
Aspect at next signal (approximated to red, yellow or green) and distance to it.
Odometer
Tracks the mileage for each locomotive on an individual basis. Displays the figure for the locomotive targeted by the camera.
Trip Meter
Functions identically to the odometer but is reset when the player presses the [T] key.
Gradient
Expressed as a percentage and displaying the figure for the locomotive targeted by the camera. For a downward slope, a negative value is displayed. Gradient is calculated for locomotives only.
When Realistic Mode is selected by the player as control method, an additional panel is displayed containing a set of on screen sliders for locomotive control. This panel is automatically hidden in Easy Mode.
Custom Variables
If the session design makes use of custom variables, the Custom HUD can display two of these variables using the Variable Show Rule. For information on how to define and modify custom session variables, see the Variable Modify Rule page.
