TTR Pilots Now Supported by First Dedicated TTR IT System

In 2019, the TTR pilots have reached an important milestone with the provision of capacities for requests based on the TTR process. Rolling Planning requests can be placed on two pilot lines, starting in mid-August 2019.

A first important finding in the TTR pilots was the need to manage infrastructure capacities in the respective IT systems. Therefore, RNE – together with the seven Infrastructure Managers (IMs) on the pilot lines – has developed and deployed a first tool to manage, display and publish capacity models: The Electronic Capacity Management Tool (ECMT). With this tool, the IMs on the pilot lines can publish all types of capacities (national and international) dedicated to Annual Planning, Rolling Planning, temporary capacity restrictions (TCRs) and maintenance windows (a sub-group of TCRs).

The ECMT will serve as a major tool to aid the pilots in capacity planning. The core element of the application is the space-time diagram where all objects of capacity planning are displayed: TCRs, capacity bands, catalogues and paths.

Capacity bands are a new concept created specifically for the TTR Programme. They play a major role in the displayed capacity and are based on line/section-related parameters (length, speed, weight, etc.), maximum running time and days, and time references (departure and arrival times). Within these capacity bands, IMs/ABs will provide a number of slots, depending on the size of the capacity band.

With the ECMT, the TTR team has gained valuable first experiences for the development of some of the most important innovative modules of the complete TTR IT landscape. This knowledge will be put to good use in the next development steps of the TCR Tool in 2020.
