Timetable Combinations


As an alternative to the already existing alternative views of a timetable for an agency type (Geography, Calendar, Manual offset) now there will be also the option Timetable Combinations.

Timetable combinations button

This view will list all possible combinations created by combining paths defined in the timetable. The paths are joined against their calendar and geography.

Main and subsidiary timetables

Each combination will be presented as a composite path. In each path section, only the time changes against the main timetable will be indicated but not the geography changes.

The origin path will be indicated in each path section by its color and a short name:

  • M – main timetable
  • Sn – subsidiary with its order number, for example, S1, S2 etc.

The order number currently exists in PCS database but is not shown anywhere and it depends on the time when the subsidiary was created. It might not match the ordering in the geography view where subsidiaries are grouped per involved agencies list. However, the colouring of the subsidiaries will be consistent with the geography view.

The selection options on the left side in the view (comparable to the selection of timetable paths) will display all valid combinations with their order number, validity period and watermark of running days. On hover, the calendar of the first reference point in the combination will be shown.

Timetable combinations

Compare combinations from this view will lead to the combinations compare view. This view is the same as the regular compare timetables view just that it makes a comparison between combination paths instead.

Compare combinations button

In the compare view, the user can select from the Applicant/IM combinations and check the differences between them. The view is using the same indication during the comparison as the compare timetable. Please find here an example with some indications about the marked differences. On the next image, it is also visible how the whole stretch is shown from origin to a destination based on the different main and subsidiary timetables.

Combinations in compare view

If no combinations can be derived the system will show an information message indicating the reason if one can be determined or general message that the process of combining the paths failed.

The reasons for failure are:

  • Inconsistent calendars at handover points in the IM timetable
  • Subsidiaries have origins and/or destinations that are not part of the main

Potentially there could be dossier structures that will produce irrelevant combinations because of the following non-exhaustive list of reasons:

  • More than one subsidiary covers the same running days on the same stretch of the main path
  • Running days in the main that is not covered by any subsidiary but should not be taken into account
