func_train is a brush entity available in all 
Source games.
It is a leftover from 
Quake that ping-pongs between the start and end of a series of path_corners. Unlike func_tracktrain, it does not rotate when turning.
Tip:This entity is not affected by the turning inaccuracy issues that func_tracktrain is, making it a good alternative for fast-moving objects.Bug:It will always try to play sounds, regardless of whether they are actually specified. This can be set to Default.Null with a volume of 0 to play no sound. [todo tested in ?]Keyvalues
Note:For Keyvalues and Inputs affecting brush rendering, see Brush entity/Rendering related keyvalues and inputs
- Name (targetname) <string>[ Edit ]
- The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g.
parentnameortarget).
Also displayed in Hammer's 2D views and Entity Report.See also: Generic Keyvalues, Inputs and Outputs available to all entities
- Pitch Yaw Roll (Y Z X) (angles) <QAngle>
- This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.
- Spawn path_corner (target) <targetname>
- The name of the first path_corner in the train's path. The train will spawn at this path_corner.
- Speed (speed) <float>
- Speed at which the train moves.
- Movement Sound (noise1) <string>
- The sound to play when the train moves.
- Stop Sound (noise2) <string>
- The sound to play when the train stops moving.
- Sound Volume (0-10) (volume) <float>
- Volume of the sounds emitted when moving and stopping.
- Crush Damage (dmg) <float>
- Amount of damage to deal to entities blocking the train.
Flags
- Non-solid : [8]
Inputs
- Toggle
- Toggle movement
- Start
- Start movement
- Stop
- Stop movement
