The objective of this deliverable, in the scope of Task 2.1 of WP2, is to describe the overall architecture of the integrated communication platform. The definition of the system architecture includes technical specifications and service requirements. The deliverable describes optical wireless communication systems and the deployment of the Open Data Management (ODM) platform in 5G. Control and management of the communication platform based on Software Defined Networking (SDN) is also described. This deliverable also describes LiFi technology application for wireless broadband and IoT connectivity within the rolling stock and provides an overview of the use cases examined in IN2DREAMS and developed in agreement with the Shift2Rail project IN2STEMPO. Among the different railway use cases studied and the 3 use cases presented in this deliverable, the use case on commercial line operation (Use Case 1), has been used to demonstrate the IN2DREAMS integrated communication platform. Train measurement setups and data portfolio are provided to validate data analytics infrastructure and design for support of selected use cases. Finally, a technical-economic evaluation is presented, including the estimation of the number of devices installed and the related costs.

Abstract Abstract As a result of rapid global urbanisation, energy and environmental sustainability are becoming increasingly significant. According to the Rail Transport and Environment Report published by International Union of Railways in 2015, energy used in the transportation sector accounts for approximately 32% of final energy consumption in the EU. Railway, representing over 8.5% of the total traffic in volume, shares less than 2% of the transport energy consumption. Railway plays an important role in reducing energy usage and CO2 emissions, compared with other transport modes such as road transport. However, despite the inherent efficiency, the energy used by the rail industry is still high, making the study of railway energy efficiency of global importance. Previous studies have investigated train driving strategies for traction energy saving.

  • The Treachery of Strategic Decisions
    The treachery of strategic decisions. An Actor-Network Theory perspective on the strategic decisions that produce new trains in the UK. Thesis submitted in accordance with the requirements of the University of Liverpool for the degree of Doctor in Philosophy by Michael John King. May 2021 Abstract The production of new passenger trains can be characterised as a strategic decision, followed by a manufacturing stage. Typically, competing proposals are developed and refined, often over several years, until one emerges as the winner. The winning proposition will be manufactured and delivered into service some years later to carry passengers for 30 years or more. However, there is a problem: evidence shows UK passenger trains getting heavier over time. Heavy trains increase fuel consumption and emissions, increase track damage and maintenance costs, and these impacts could last for the train’s life and beyond. To address global challenges, like climate change, strategic decisions that produce outcomes like this need to be understood and improved. To understand this phenomenon, I apply Actor-Network Theory (ANT) to Strategic Decision-Making. Using ANT, sometimes described as the sociology of translation, I theorise that different propositions of trains are articulated until one, typically, is selected as the winner to be translated and become a realised train. In this translation process I focus upon the development and articulation of propositions up to the point where a winner is selected. I propose that this occurs within a valuable ‘place’ that I describe as a ‘decision-laboratory’ – a site of active development where various actors can interact, experiment, model, measure, and speculate about the desired new trains.

  • An Influence of a Complex Modernization of the DC Traction Power Supply on the Parameters of an Electric Power System
    MATEC Web of Conferences 180, 02001 (2018) https://doi.org/10.1051/matecconf/201818002001 MET’2017 An influence of a complex modernization of the DC traction power supply on the parameters of an electric power system Jerzy Wojciechowski1,*, Krzysztof Lorek2, and Waldemar Nowakowski1 1Kazimierz Pulaski University of Technology and Humanities in Radom, ul. Malczewskiego 29, 26-600, Radom, Poland 2Sonel S.A., ul. Wokulskiego 11, 58-100, Świdnica, Poland Abstract. Urban and suburban public transport constitute basics of functioning of modern, urbanized metropolises. It is a comfortable, economic and ecological means of transportation. Thus, a stable and fast growth of this solution. One of its components is the power supply system. It should allow functioning of the whole transportation system, maintaining the following criteria: energy efficiency and modernity. These criteria have contributed to creation and modernization of power supply systems. Where it comes to DC systems, such an investment includes: replacing 6-pulse rectifiers with 12-pulse rectifiers and raising rated supply voltage. In this article, the authors have presented research results, based on measurements of electrical energy parameters before and after a modernization of a suburban transportation traction system. These parameters have been divided into two groups. The first consists of parameters mentioned in the EN50160 norm. Another group consists of parameters not mentioned in the norm. What has been presented are waveforms and graphs showing these parameters. In the final part of the article a discussion on reasonability of introducing new, modernized traction power supply system for suburban transportation has been performed. 1 Introduction and electrical energy given back to the units are basic technical problems of DC traction power supply systems The issue of energy efficiency in the traction power [6-14, 18-22].
