TTR Process: Introduction

The redesigned timetabling process consists of several components to cover advance as well as short-term planning and provides products for stable as well as variable market needs. The process starts five years before the respective timetable period commences and ends with the conclusion of that period.

The following main components constitute the central building blocks of the process:

  • Capacity Strategy
    International alignment on events with a large impact on capacity availability (such as extended track closures, intended increase of commuter services or newly opened lines, etc.).
  • Capacity Model (with capacity partitioning)
    A preliminary timetable in which blocks of capacity are assigned according to the identified market needs.
  • Capacity Planning & Publication of Capacity Supply
    Subsequent to the Capacity Model, in the Capacity Planning phase all objects (TCRs and commercial parts) will be displayed in a 365-days capacity diagram. This diagram, also known as Capacity Supply, is published at the end of this phase and shows the capacity which is available for booking.
  • Temporary Capacity Restrictions (TCRs)
    Better coordination of planned temporary capacity restrictions so that traffic flows despite necessary track works.

As regards path requests and the allocation of infrastructure capacity, three distinct request methods will ensure that all market needs are covered:

  • The Annual Request
    A request method for the stable market to provide capacity early for commercial use (e.g. early sale of tickets)
  • The Rolling Planning Request
    An innovative and flexible method to allow capacity requests to be placed much closer to operation
  • Short Term Request

Traffic needs to be planned permanently. IMs and applicants have the possibility to request, update, improve, and change capacities permanently even after the path request deadline. This can be achieved with ad hoc requests, requests for modification/alteration, path optimisation, and cancellation.

Some general process components will be introduced as well to ensure smooth execution and continuous improvement of TTR:

  • Leading entities
    To effectively ensure progress in, and control over, the process, responsibility for certain steps will be assigned to specific stakeholders (e.g. one IM/AB is responsible that all IMs/ABs involved in a path offer provide this path offer in time).
  • Allocation rules
    Common rules will apply to determine where priority should be given in case of conflicts in path allocation.
  • Key Performance Indicators (KPIs)
    TTR is intended as a living process that adapts to evolving market needs through continuous evaluation and improvement. For that purpose, KPIs will be defined in the TTR pilots.

When implemented, these components will provide the market with the stability of reliable planning parameters on the one hand, and sufficiently flexible capacity products on the other hand.
