Hi,
your "networkNode" and your "sections" are part of a high-level
infrastructure, which is referenced by most timetables. Most planned
trains are driving from "station A" to "station B". The "networkNodes"
could be found as "operationControlPoints" in the infrastructure, but the
"sections" between these points are still missing. This is a known lack.
The reason is, that it is easier to agree on a common description of the
tracks and switches than on the network, because "sections" are defined
differently in every railway.
Nevertheless, "networkNodes" and "sections" should be part of the
infrastructure not the timetable. A timetable could reference them via
"posID" and "sectionID" in the way you described.
Cheers,
Joachim
