TTP2027

1.    Timetable start/end date

  • Timetable start date (X): 2026-12-13
  • Timetable end date: 2027-12-11

 

2.     Adhoc start date

20.10.2026  at 00:00: the first moment for placing Adhoc Path Requests for the running timetable 2027.

From 05.11.2026 at 00:00: Applicants can submit their path requests to IMs/ABs/RFCs. From the TTP028 a new milestone (X-1.25) is introduced to the system configuration to block the early submission of Adhoc path requests.

 

3.     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 reference train switches to the Booked phase after submitting the Adhoc Request Offer. The Adhoc Pre-accepted process type does not contain the post-processing phase.

 

4.     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.

 

5.     Adhoc automatic promotions

5.1     Automatic one-time promotions

The Adhoc process types are not deadline-driven, and one-time deadline promotion configuration does not exist.

5.2     Daily Promotions (Adhoc)

An adhoc promotion is linked to the daily promotion configurations of both the previous and the current timetable periods, so that the promotion is applied consistently.
