Reference Point & Construction Starting Point

Content

The reference point of the timetable is set by PCS automatically always to the origin point of the timetable. The requested/offered calendar is always defined for this point and for all the other path sections below the offsets are calculated from this point. Applicants are still welcomed of course to indicate their interests in the way of construction of the path. That is why Applicants can use the construction starting point and they can put the symbol in any location. Still, only one path section can be marked as a construction starting point. It is the key starting point for timetable construction. If the first point is set up as the construction starting point then the construction has to be done forward. If the last point is set up as the construction starting point then the construction has to be done backward. If there is some point in the middle set up as the construction starting point then the construction has to be done forward and backward from this point.
