D5.4 Technical Specification of Wagon Power System and Communication System

This document represents “Deliverable 5.4 Technical Specification of Wagon Power System and Communication System” of the ERJU flagship project FP5-TRANS4M-R. This document reports results of task 5.5 “Technical Specification and Validation/Test Plan of the DAC Power and Data Communication solution”.

The aim of this document is to provide the requirements specification defining the interoperable system interfaces and their basic functions for the Power and Communication System on wagon side as well as on traction unit side. A basis were the recommendations and results from EDDP, which have been refined and adapted. The requirements are also based on the reference system architecture from task 3.2 and task 3.3. Additional input requirements from industry-wide stakeholders – such as TIS – were also incorporated into this requirement specification.

The requirements were developed in many technical workshops with experts. The inputs have been considered, the technical concepts were evaluated, and the result defined as requirements.

The focus of this document is the subsystem requirements. These describe what is required for the interoperable system interface and further define the basic functions of the Power System and the Communication System required to operate the Full Digital Freight Train in Europe. The chapter “Systems of interest and input requirements” explains the conditions and constraints under which the requirements to be interpreted. The chapter “Technical subsystem specification” defines the requirements applicable to Power System and Communication System.
