TTR IT Landscape approved by RNE General Assembly

RNE and FTE designed and proposed a new European IT environment, the TTR IT landscape concept, to support the communication between stakeholders’ systems and the RNE central system. The members of RNE and FTE evaluated this concept, taking into account their national project portfolios, and the conclusion was that a smoother approach was needed for the implementation. Therefore, RNE and FTE proposed to implement the TTR IT landscape in a stepwise approach.

The Stepwise Approach

The TTR IT landscape will be gradually implemented, and be ready for TT 2025.

  • Step 1: implementation of a set of minimumrequirements (basic requirements)
  • Step 2: full implementation of all TTR IT functionalities

Implementation of the Set of Minimum Requirements

Generally, in step 1 existing systems shall be used as far as possible. The deadline for the implementation of the minimum requirements is August 2023. RNE has been developing the so-called Electronic Capacity Model Tool (ECMT) to support the TTR pilots. In step 1 of the TTR IT landscape implementation, the ECMT will also cover the functionalities of the Capacity Hub and Capacity Broker modules (described below).

Full Implementation of TTR IT Functionalities

In the second step of the TTR IT landscape implementation, the complete set of functionalities shall be covered. In this step, the Capacity Hub and Capacity Broker will be extended to provide the full functionality defined in the TTR IT landscape. In addition, all other functionalities will be improved and further developed as needed.

Overview of the TTR IT Landscape Modules

Functionalities needed for the advance planning are covered by the following modules:

  1. Capacity Hub – a module for capacity modelling, planning and product development (to be covered by the ECMT in step 1).
  2. TCR – a module for the international harmonisation and coordination of known temporary capacity restrictions.
  3. Messaging Module – a module that ensures and establishes communication between the national systems of the stakeholders and the central RNE systems. The RNE Common Interface (CI), as a part of the Common Components System (CCS), will be used.
  4. Big Data – a module responsible for keeping all infrastructure data up-to-date.
  5. Capacity Needs Announcements – a module that RUs will use to indicate their expected needs for capacity in the next timetable year. There is currently no international tool for this purpose.

Functionalities needed for path planning are covere by the following modules:

  1. Path Request Management – a module for the preparation and harmonisation of path requests between the partners. The RNE PCS (Path Coordination System) has been developed to support the preparation, harmonisation, and submission of path request and will be used for this functionality.
  2. Path Management – a module that optimises international path coordination by ensuring that path requests and offers are harmonised by all involved parties. Again, PCS will be used to cover this functionality.
  3. Capacity Broker – collects all requests from the RUs side and gives feedback if they match the available capacity. The functionality of this module is foreseen to be covered by an algorithm running in the Capacity Hub (ECMT) and also connected to Path Request and Path Management modules.
  4. Train Harmonisation – a module for the harmonisation of train objects at international level to harmonise path requests regarding the train characteristics such as load, weight, length, border handling, interchange etc. There is currently no international tool for this purpose.
