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 ?]
