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 ?]

Tip:As brush entities are lit using static lightmaps, lighting on this entity may look weird when it moves from its original position. If this is an issue, consider converting the brushes to a prop, changing the brushes to clip or skip, and parenting the converted model to this entity.

Keyvalues

Note:For Keyvalues and Inputs affecting brush rendering, see Brush entity/Rendering related keyvalues and inputs

Name (targetname) <string>
