What Earl said is what I understand as well. If the inferior train is late to a timetable meeting the point superior train must wait until the inferior gets there unless the dispatcher issues orders to the contrary. This is to prevent head on collision if the inferior train is delayed enroute since leaving the last station before the meet.
An example would be Train 115 leaving Gato on time but stopping for some reason down the line. Having Train 116 wait at Caracas would avoid having one train having back up.
