 ====== Train HUD ======
+Passengers and drivers of trains get more information about the train they are in with a HUD.
-===== Driver =====
+===== Graphical driver HUD =====
-For the driver, the current train HUD looks similar to the following:
+The graphical driver HUD was introduced in version 2.2.0 and updated in 2.2.1.
+{{:usage:ywang_trainhud_design_1.png?direct&400|}}
+The HUD shows:
+  * The speed in m/s indicated by the two-digit 7-segment display.
+  * The corresponding speed shown as a white bar.
+  * The physical speed limit (i.e. the speed limit of the wagons themselves), if lower than 20m/s.
+  * The driving direction of the train as a lever
+  * The throttle and brake controls of the train shown as a combined lever
+  * "ATC" when ATC is active
+  * "LZB" when LZB is active
+  * "Shunt" when shunt mode is active
+  * The signal aspect of the next signal shown by two rectangles and a number:
+    * If the upcoming signal allows proceeding without any speed limit, the indicator is shown in green.
+    * If the upcoming signal has a speed limit that is higher than 0m/s, the indicator is shown in orange, and the speed limit is shown as a red triangle pointing downward at the speed bar.
+    * If the upcoming signal does not allow proceeding, the indicator is shown in red.
+  * The status of the doors.
+  * The speed current speed limit of the train (if present) shown as a red vertical bar
+  * The ATC target speed (if present) shown as a cyan triangle pointing up
+===== Passenger =====
+Passengers only see the text shown inside the train, as configured on the onboard computer or LuaATC.
+===== Text-based driver HUD =====
+A text-based HUD was used before version 2.2.0. It looks similar to the following:
 <code>
  [F] {B - >o< +} >|< >|<

     * ''>o<'' when the speed of the train is constant
     * ''>+<'' when the train accelerates
+  * The doors that are open:
+    * ''>|< >|<'' when doors on both sides are closed
+    * ''|<>| >|<'' when doors on the left side are open
+    * ''>|< |<>|'' when doors on the right side are open
   * The current speed of the train: four ''+'' show that the train moves at 4m/s (15km/h)
+  * An ''S'' in the speed indicator when shunt mode is active
   * The operation mode of the train:
     * When the train is manually controlled, ''Manual operation'' is shown

       * The ATC command and delay (if any) is shown after the ATC target speed
     * When LZB is active (e.g. when the train is approaching the end of the track) **and** the train is manually controlled, ''-!- Safety override -!-'' is shown.
