This page is about Source train entities. Train entities move along a predetermined track, and can look represent anything that moves.

Entities

Main entities

• func_tracktrain - The part that moves. Brush-based.
• path_track - A waypoint on the track. Invisible and non-solid.
• func_tanktrain - Train that attacks and dies.

Other entities

• func_platrot - Raises or lowers a stopped train, turning as it changes height (as seen in Half-Life).
• func_traincontrols - Lets players control the train.
• func_trackchange
• func_trackautochange

Entities not in the FGD

• func_train
• func_plat - Raises or lowers a stopped train (without rotation).

Notes

• If you want a prop to behave as a train, parent it to an invisible func_tracktrain.
• Trains must be constructed facing east (in the Top viewport of Hammer, this is facing right) otherwise they will be pointing the wrong direction in-game. They will turn themselves to face the correct direction.
• You don't need to create each path_track by hand. Create the first one, then Shift-drag it to create another; the new one will be automatically linked from the previous one. This works even for inserting new path_tracks between existing ones.
