CORRIDOR 10 - a sustainable way of integrations
ÖBB-Method (see figure 4):
Start of the interlinked level of occupation:
- All trains which timetable graphs, also partially, extend into the defined calculation period
(see fig. train 1-3).
- The trains entering the calculation step before the starting time are not changed in the
process of compression (see at train number 1 and 2).
- In the process of compression the first train entering the calculation step after the starting
time (train number 3) is pushed to the train ahead until the first block section occupation is
equal to the starting time.
End of the calculation period:
- The last train entering the section before the calculation period is over. The remaining
timetable graph may be outside of the calculation period (see fig. train number 4).
- When the process of compression has been finished the occupation time comes to the
result of the difference between the starting time of the calculation period and the finishing
time of the first block section occupation belonging to the last train.

After the program determines which train passes are to be compressed, the timetable compression
begins with
the first train that travels the entire calculation step in the calculation period (2.a.) (ÖBB- and
DB-method) or
the first train that starts in the calculation step after the calculation period has begun and
passes a portion of the line (2.b.) (ÖBB- and DB-method) or
