TTP2025

1.    Timetable start/end date

  • Timetable start date (X): 2024-12-15
  • Timetable end date: 2025-12-13

2.     Ad-hoc start date 

15/10/2024  at 00:00: the first moment for placing ad-hoc path requests for the running timetable 2025.

3.     PCS Automatic Promotions (Adhoc)

There are no automatic promotions that exist for the Adhoc process type.

4.     Adhoc Pre-Accepted (Harmonized)

Applicants can choose the Adhoc Pre-Accepted process type when creating their path request. In this case, applicants decide that they will automatically accept the IMs/ABs’ Adhoc offers. This means that in this case there is no Acceptance phase, the dossier switches to the Active Timetable after submitting the Ad-hoc Request Offer.

5.     Adhoc Path request (Partially Harmonized)

It starts as the regular Adhoc Path Request, but the leading applicant can decide in the Harmonization phase that changes the process from fully harmonized to partially harmonized. The partial harmonization process works the same way for applicants as for IMs/ABs. The applicant-IM pairs move independently through the phases until the Acceptance phase where the request must be harmonized again.

A dossier can be created in the open phase until 14.04.2025, at 23:59, having in mind that if the path request is placed after the NPR deadline, it will be automatically created as a Late Path Request.

3.1.2 Harmonization

  Harmonization starts depending on the leading applicant.

3.1.3 Pre-booking

Between 15.04.2025 at 00:00 and 27.04.2025 at 23:59: Corridor OSSs of the Rail Freight Corridors will pre-book Pre-arranged Paths (PaPs) or will pre-book the accepted alternative PaPs.

3.1.6 Post-processing

Between 09.08.2025 at 00:00 and 25.08.2025 at 23:59, IMs/ABs/RFCs prepare the final answers to the customers.  Once all IMs/ABs/RFCs have finished their final adjustments, the dossier can be promoted to the Final Offer phase.

26.08.2025 at 00:00: from this date on, all involved applicants will decide whether they can accept and obtain or refuse the offered final timetable version. 

Both the Draft Offer and the Final Offer can be sent later.

3.1.8 Active Timetable

Once the dossier reaches the Active Timetable the dossier contains the agreed final state of the path for a particular timetable period.  In this phase, path requests are waiting for the start of the timetable period.

When the timetable period starts the leading entities should Close the dossier if there will NOT be any excepted future deviation or changes.

PCS opens the opportunity to ask for the change of some elements on the already finally agreed path from this phase:

  • Applicants can start the Path Modification process
  • IMs/ABs can start the Path Alteration process

3.2 Automatic one-time promotions

3.4 Actions to be performed

a.  Advice for requesting NPR PaPs

If the path request is created close to the deadline the leading applicant can use the “last chance” to insert PaPs to the dossier before the New Path Request deadline, and we recommend doing it by 14.04.2025 at 22:59. The leading Applicants will be able to check the dossiers once more in the Harmonisation phase, and the dossiers will be automatically switched to Pre-booking phase at 23:00 h on the same day.

Conditions to switch:

  • complete all missing data
  • all involved applicants’ path-related lights are green

b.  Remaining Dossiers: Harmonization conference -> Harmonization

14.04.2025 at 04:00: if there are any remaining dossiers in the Harmonization Conference, they will be switched to Harmonisation  

Conditions to switch: only if dossiers that have already ‘acknowledged’ the Feasibility Study Result.

With this approach, the leading Applicants will be able to check the dossiers once more in the Harmonisation phase before the Path Request Deadline, and the dossiers will be automatically switched at 23:00 h on the same day.

c. Just started the Harmonization conference

Dossiers that have just started the Harmonization Conference will be kept in the Harmonization Conference.

The leading applicant must ensure that all participants agree with the request. This process is controlled by making sure that all ‘lights’ are green. Unless all lights are green it will not be possible to switch the dossier automatically to path request.

4.     Feasibility Study (FS)

4.1 Automatic one-time promotions

a. Harmonization-conference -> Feasibility Elaboration Conference

20.01.2025 at 23:00: The “time limit” for placing feasibility study requests for timetable 2026. Automatically switching all dossiers that are in the Harmonization Conference to the Feasibility Elaboration Conference.

NEW: the last day for the submission of feasibility studies for the TTP2026 is changed to February 16, therefore, based on the approval of the PCS CCB members on 14.10.2024 at the Bi-weekly report meeting, a new configuration has been introduced to PCS, which will be a repeat of the original configuration of January 20 on the 16 of February. The old configuration (20th of January) will still be retained to align with the FTE A passenger traffic conference and the new configuration will assist passenger traffic users in promoting the dossiers on the new deadline date (16th of February).

16.02.2025 at 23:00: The “time limit” for placing feasibility study requests for timetable 2026. Automatically switching all dossiers that are in the Harmonization Conference to the Feasibility Elaboration Conference.

Both configurations above have the same conditions to switch!

NEW: the last day for the submission of feasibility studies for the TTP2026 is changed to February 16, therefore, based on the approval of the PCS CCB members on 14.10.2024 at the Bi-weekly report meeting, a new configuration has been added to PCS, which will be a repeat of the original configuration of January 21 on the 17 of February. The old configuration (21st of January) will still be retained to align with the FTE A passenger traffic conference and the new configuration will assist passenger traffic users in retrieving unfinished feasibility studies on the new deadline date (17th of February).

17.02.2025 at 23:00: automatically switch all dossiers that are in Harmonization Conference back to Harmonisation

Both configurations above have the same conditions to switch!

Conditions to switch: all involved IMs/ABs/RFCs path-related lights are green

4.3 Actions to be performed

In case when the feasibility study CAN NOT be completed by the IM/AB on time, and they decide that this dossier should NOT be switched automatically to Harmonisation on 17.03.2025 at 23.00 h. then the IM/AB has to switch this dossier manually from Feasibility Elaboration Conference to Feasibility Study Elaboration before 17.03.2025 at 23.00 h.

b. Feasibility Study Elaboration -> Feasibility Study Result (Not completed – Step 2)

Afterwards, the switching from Feasibility Study Elaboration to Feasibility Study Result has to be done manually by the coordinating IMs/ABs.

5.1.7 Final Offer

All involved applicants will decide whether they can accept and obtain or refuse the offered final timetable version.
