Train HUD

Passengers and drivers of trains get more information about the train they are in with a HUD.

The graphical driver HUD was introduced in version 2.2.0 and updated in 2.2.1.

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

Passengers only see the text shown inside the train, as configured on the onboard computer or LuaATC.

A text-based HUD was used before version 2.2.0. It looks similar to the following:

 [F] {B - >o< +} >|< >|<
Speed: |++++___________|> 15 km/h
Manual operation

The display shows:

• The text that is normally shown inside the train, if any.
• The driving direction: [F] when driving forward or [R] when driving in the reverse direction.
• The lever of the train:
  • >BB< when the emergency brake is applied
  • >B< when the normal brake is applied
  • >-< when the train rolls to stop
  • >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
  • When ATC is active:
    • The target speed is shown similarly to the current speed of the train
    • 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.
