A moving platform that the player can ride. It follows a path of path_track entities.

properties

• First Stop Target target(target_destination)
  The name of the first path_track in the train's path. The train will spawn at this path_track. It will also turn to face direction indicated by the 'Orientation Type' setting.
• Max Speed (units / second) startspeed(integer) - default: 100
  The maximum speed that this train can move. Any speeds applied to this train, such as by path_tracks or SetSpeed inputs, will be clipped to this maximum value.
• Initial Speed (units / second) speed(integer) - default: 0
  The speed that the train will move at after it spawns, 0 = stopped.
• Change Velocity velocitytype(choices) - default: The method through which this train changes its velocity as it moves along the path.
  • 0 - Instantaneously
  • 1 - Linear blend
  • 2 - Ease in/ease out
• Change angles orientationtype(choices) - default: The method through which this train changes its orientation as it moves along the path.
  1
  • 0 - Never (fixed orientation)
  • 1 - Near path_tracks
  • 2 - Linear blend
  • 3 - Ease in/ease out
• Distance Between the Wheels wheels(integer) - default: 50
  Used for turning and stopping.
• Height above track height(integer) - default: 4
  The height above the track that this train moves.
• Bank Angle on Turns bank(string) - default: 0
• Damage on Crush dmg(integer) - default: 0
  The amount of damage this train does to entities that block it.
• Minimum Light Level _minlight(string)
  The minimum level of ambient light that hits this brush.
• Move Sound MoveSound(sound)
  A sound that is played (and looped) while the train is moving.
• Move Ping Sound MovePingSound(sound)
  A sound that is played more frequently as the train speeds up.
• Start Sound StartSound(sound)
  A sound played when the train starts moving.
• Stop Sound StopSound(sound)
  A sound played when the train stops moving.
• Volume (10 = loudest) volume(integer) - default: 10
• Min pitch (1-255, > 100 = higher) MoveSoundMinPitch(integer) - default: 60
  The sound pitch value that the train will approach as it comes to a stop.
• Max pitch (1-255, > 100 = higher) MoveSoundMaxPitch(integer) - default: 200
  The sound pitch value that the train will approach as it approaches its max speed (or 1000 inches/second if the 'Use max speed for pitch shifting move sound' flag is not set).
• Min move sound interval MoveSoundMinTime(float) - default: 0
  Minimum interval at which to play the move ping sound.
• Max move sound interval MoveSoundMaxTime(float) - default: 0
  Maximum interval at which to play the move ping sound.

inputs

• Kill(void)
  Removes this entity from the world.
• KillHierarchy(void)
  Removes this entity and all its children from the world.
• AddOutput(string)

  Causes this entity's OnUser2 output to be fired.
• FireUser3(void)
  Causes this entity's OnUser3 output to be fired.
• FireUser4(void)
  Causes this entity's OnUser4 output to be fired.
• SetParent(string)
  Changes the entity's parent in the movement hierarchy.

• SetSpeedReal(float)
  Set the speed of the train. Must be a positive value from 0 to max speed.
• Stop(void)
  Stop the train.
• StartForward(void)
  Start the train moving forward.
