D3.2 – Use cases and scenarios for ETCS L3 demos on G1 regional lines

Within the global aims of the FutuRe project to ensure the long-term viability of the regional railway by reducing the total cost of ownership (TCO), WP3 and its sub-tasks have the goal of performing some preparatory activities for demonstrators to be used to demonstrate the validity and the relevance of the existing or new interoperable standards and technical solutions on G1 lines and to ensure their long term viability.
The identification and description of the most relevant Use Cases applicable for such demonstrators, with particular focus on ETCS L2 ones, is the scope of Task 3.2.
In this context, to achieve the expected targets, two approaches can be followed: using the solution already available from FP2-R2DATO or adopting a dedicated solution developed for the regional environment. Both approaches are used in this project. How the targets will be achieved in the different contexts will be demonstrated in the continuation of the activities of the FutuRe WP8 project.
Any possible difference compared to other specifications (e.g. FP2-R2DATO or System Pillar) is because of the specific objectives to be achieved in the regional environment. As part of the demonstrators’ testing activities, specific evidence to the rationales of each design choice will be provided.
The following operational pillars have been adopted for selecting the relevant UCs:
• Any simplification from the operational point of view is pursued, to get the lowest operational cost of the regional line;
• Any operational scenario must be robust in comparison to the technical or operational degraded conditions;
• Minimizing the manual contribution and activities by signallers (Control Room operators) and train drivers;
• The selected Use Cases should belong to the most realistic (nominal and degraded) operational conditions applicable to a railway line.
The detailed analysis performed by the members of Task 3.2 subgroup led to the identification of N.98 potential Operational Scenarios; 93 out of 98 have been evaluated as relevant and described as a sequence of events according to a predefined template.
Their positive contribution to the achievement of the final and main goals will be analysed in the next future, with the possible integration of additional Use Cases or sub Use Cases for clarifying, as needed, some critical operational aspects.
This document, in its final release, shall be the basis as well for the demonstration activities performed in T8.3 (Development of individual ETCS L3 demonstrators on G1 regional lines). In the same delivery, a cross check with relevant R2DATO Use Cases will be deployed.
