Project Structure

•   WP1: Scientific Coordination

The main objective of this Work Package is the overall project technical coordination among WP leaders, in conjunction with the Technical Leader and the Coordinator. This includes proposing successful problem solving solutions, ensuring proper integration and the appraisal of project risks.

•    WP2: Evaluation of interference currents – Handling of transients

Currently, there are no standards/norms or procedures addressing the effects of transients on track circuits. The only exception is the Netherlands, where they have started to address this problem in a formal manner (software application to evaluate all interference currents for compatibility with, at this stage, a common preferred track circuit). The problem is recognised by several system operators as occurrences arise on their networks. Most operators use a variety of ways to deal with this issue, but this is often done only on a case-by-case basis. Solutions are seldom documented and thus the expertise resides with individuals rather than with the organisations. The question is always: “How should we handle those transients that affect data acquisition during certification tests?”

In addition to the operators’ experience, vehicle and track signalling systems suppliers also have extensive amounts of data with respect to transients. Over the years, this data has accumulated with regards to work, product introduction and warranty service phases. The sharing of operator and manufacturer data with the European community of experts is a key part of this work package.

•    WP3: Qualification of EMC cross accepted test tracks – 15 kV

For the validation of the actual version of the Technical Standard (TS 50238-2) for 15 kV/16.7 Hz power supply systems, a measurement campaign has been carried out by DB AG, SBB and ÖBB in 2010. The measurements had been done with a locomotive with different capacitive input impedances (addition capacitors) for the simulation of roof cables with different lengths. The evaluation of the measurement data was focused on the comparability of the measurement results for a train, which runs without any changes of traction unit and traction software, on the networks of the three countries. No detailed analysis and evaluation of the influence of single infrastructure parameters has been done to date.

Based on the large number of measurement data, the experience and the knowledge of the WP members in the field of interference current measurement and evaluation, and the knowledge in numerical simulation, the influence of single infrastructure parameters should be analysed and relevant criteria for the definition and selection of future test lines should be deviated. The defined parameters for test tracks, or defined test tracks of each country, should be validated by a final measurement campaign. The results will be transferred to CENELEC (the European Standardisation Organisation) for the preparation of the EN 50238-2 Standard.

•    WP4: Qualification of EMC cross accepted test tracks – 25 kV

The objective of this work package is to define and propose Europe-wide cross accepted test tracks for the 25kV / 50 Hz power supply system. These test tracks would give the possibility of performing conducted emission tests for several countries and infrastructures only once. The results of these tests then could be used for certification in all countries using 25 kV AC electrification systems.

A better understanding of the influence of test tracks and infrastructure could also lead to a harmonized test philosophy. The measurements and simulations will help us to fully understand the influence of vehicles with roof cables and thus simplify the design and the certification of these types of vehicles.

•    WP5: Qualification of EMC cross accepted test tracks – DC

The objective of this work package is to study the influence of test tracks on the conducted emissions generated by vehicles on DC power supply systems and to define, and later propose, Europe-wide cross accepted test tracks for the DC power supply systems.

The idea behind the notion of cross accepted test lines would be to have e test tracks which would be recognized by the different countries in Europe in order to accept the measurements of harmonic currents performed in one country without having to repeat the measurements in another country with the same power supply system. It means that during the project, test campaigns will be organised in several countries in order to measure the interference currents generated by the same vehicle on different test lines with the same DC power supply system.

The analysis of the results will make the differences clear, and if they are too high or if the test results can be used within the same power supply system, as well as the influential parameters of the infrastructure on the conducted emissions of vehicles. The characterisation of these parameters will be deduced also from theoretical models and computer simulations.

•    WP6: Test specification for rolling stock for non-electrified lines

In the current climate, when more routes are opened up for freight traffic, there is still a considerable effort required to ascertain compatibility between freight trains consisting of various combinations of locomotives and wagons. Indeed the various ways of connecting these together has an effect on the current seen in the rails and affects the train detection system. The integrity of the train detection system should be maintained under normal and degraded conditions of the rolling stock passing over it, which inevitably leads to lengthy compatibility proceedings. As a consequence, every single EU country has established rules and methods in order to handle influencing currents for track circuits on non-electrified lines.

With respect to these rules and methods, a general recommendation for rolling stock preventing any type of track circuits from interfering currents will be provided. This recommendation should be applicable in each country of the EU in order to integrate the national certification processes. The aim of this Work Package is to enable, for the first time, harmonisation of rolling stock in the EU in terms of current interfering with track circuits on non-electrified lines.

Finally, measurements should be performed to prove Electromagnetic Compatibility between rolling stock and track circuits, in order to check the consistency of this recommendation. For this reason, the final task of the Work Package concerns validation tests on dedicated test tracks.

•    WP7: Dissemination and exploitation of results

This Work Package addresses all high-level objectives in that none of these would be possible without the acceptance of the project results by European standardisation & regulatory authorities. The widespread and targeted dissemination of project outputs is vital to the acceptance and implementation of technologies and methods developed. Implementation of the EUREMCO proposed solutions will generate significant cost reductions for authorisation, for the placing in service of railway subsystems against TSI CCS (Technical Specification for Interoperability relating to the subsystem “Control-Command and Signalling”) and existing national rules.

•    WP8: Administrative, Financial, Strategic Coordination and Quality Management

The objectives of this Work Package are to set up a Project Management Office, responsible for the following:
•    Managing and controlling  project resources;
•    Monitoring and controlling project financial and administrative procedures;
•    Supporting communication between all members of the  Consortium and project stakeholders; ;
•    Ensuring and facilitating internal communication;
•    Providing managerial assistance and supporting  the Steering Board, the Technical Leader and WP Leaders;
•    Performing quality management.
