func_tracktrain #

The train controls can be toggled via trigger_vehiclecontrols.

Custom move, start and brake sounds.
Use Sound Override - custom use sound to play instead of plats/train_use1.wav.
Sound radius - configure platform sounds attenuation.
Collision with corpses - allows to ignore collision with dead monsters. Corpses won’t block this train and won’t get crushed.
Touch proxy targetname - create an invisible proxy entity that can touch triggers and give it this name. The entity will move with a train at its origin. The trigger_multiple or trigger_once can check against this targetname or the func_tracktrain_proxy classname. This hack is needed because the trains and vehicles have such physics that don’t touch triggers.
