Download or read book Electromagnetic Compatibility in Railways written by Ade Ogunsola and published by Springer Science & Business Media. This book was released on 2012-08-14 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: A railway is a complex distributed engineering system: the construction of a new railway or the modernisation of a existing one requires a deep understanding of the constitutive components and their interaction, inside the system itself and towards the outside world. The former covers the various subsystems (featuring a complex mix of high power sources, sensitive safety critical systems, intentional transmitters, etc.) and their interaction, including the specific functions and their relevance to safety. The latter represents all the additional possible external victims and sources of electromagnetic interaction. EMC thus starts from a comprehension of the emissions and immunity characteristics and the interactions between sources and victims, with a strong relationship to electromagnetics and to system modeling. On the other hand, the said functions are achieved and preserved and their relevance for safety is adequately handled, if the related requirements are well posed and managed throughout the process from the beginning. The link is represented by standards and their correct application, as a support to analysis, testing and demonstration.

La evaluación económica de proyectos puede ayudar a los gobiernos a formarse una idea más precisa sobre los beneficios esperados de distintas líneas de actuación que absorben dinero público para resolver un mismo problema de transporte. En este informe se trata de determinar las circunstancias en las que la inversión en alta velocidad es socialmente deseable y en que otras la sociedad gana posponiendo la inversión. La red de alta velocidad puede construirse gradualmente, añadiendo nuevas líneas una vez que la evaluación económica muestra una rentabilidad social positiva.
Download or read book EMC in Railways Electromagnetic Field Measurement written by Andrea Mariscotti and published by ASTM Analysis, Simulation, Test and Measurement. This book was released on 2016 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Railway and metro systems embed modern technologies and interface with external systems, outside world and humans. This book focuses on electromagnetic field coupling and its experimental assessment. Electromagnetics, transmission lines, antennas, the spectrum analyzer, time-frequency transforms, probability, statistics and uncertainty are the background. Six chapters follow that discuss standards, scientific literature, measurement methods, procedures. Emissions of rolling stock, line and substation using 2006 and 2015 versions of EN 50121 are considered, discussing infrastructure influence, variability and synchronization with train operation, consistency. RF emissions of current collection system and impact to radio communications are evaluated by means of joint time-frequency transforms, APD and BER. Low-frequency magnetic field is a possible threat to susceptible medical and scientific equipment. For human exposure of personnel and passengers the presence of large power equipment, the relatively short distance and the time-varying nature of sources shall be taken into account with suitable evaluation methods against EN 50550 and ICNIRP limits. The aim is supporting EMC and test engineers, R&D and academic staff in their activities, while planning and preparing on-site tests in modern electrified transportation systems, bridging analysis and simulation. Examples and practical considerations are the result of many years of experience of EMC testing in railways.

Part two focuses on a number of case studies from Europe, Asia and North America written by an international group of experts.
Download or read book Railroads and the Transformation of China written by Elisabeth Köll and published by Harvard University Press. This book was released on 2019-01-14 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a vehicle to convey both the history of modern China and the complex forces still driving the nation’s economic success, rail has no equal. Railroads and the Transformation of China is the first comprehensive history, in any language, of railroad operation from the last decades of the Qing Empire to the present. China’s first fractured lines were built under semicolonial conditions by competing foreign investors. The national system that began taking shape in the 1910s suffered all the ills of the country at large: warlordism and Japanese invasion, Chinese partisan sabotage, the Great Leap Forward when lines suffered in the “battle for steel,” and the Cultural Revolution, during which Red Guards were granted free passage to “make revolution” across the country, nearly collapsing the system. Elisabeth Köll’s expansive study shows how railroads survived the rupture of the 1949 Communist revolution and became an enduring model of Chinese infrastructure expansion. The railroads persisted because they were exemplary bureaucratic institutions. Through detailed archival research and interviews, Köll builds case studies illuminating the strength of rail administration. Pragmatic management, combining central authority and local autonomy, sustained rail organizations amid shifting political and economic priorities. As Köll shows, rail provided a blueprint for the past forty years of ambitious, semipublic business development and remains an essential component of the PRC’s politically charged, technocratic economic model for China’s future.

Download or read book Railway Transportation in South Asia written by Saptarshi Mitra and published by Springer Nature. This book was released on 2021-08-20 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses policy instruments for sustainable infrastructure developments. Railways are one of the most important developmental instruments of a region, province, or country. They play a crucial role in economic development, urban growth, urban mobility, regional susceptibility, market integration, and world trade. Railways are an integral part of regional and urban development, both in terms of freight and passenger transport. By offering case studies from various regions and cities in South Asia, this book examines the evolution of railway transportation and the impact of these infrastructure projects on regional and urban development. It examines the interactions between evolving infrastructures and competing demands and considers the negative and positive externalities of railway transportation for people, places, and locations. The contributions analyze issues such as network infrastructure planning and technological development, passenger mobility and satisfaction, vulnerability to environmental impacts, and cross-border trade.

Download or read book The Railway Journey written by Wolfgang Schivelbusch and published by Univ of California Press. This book was released on 2014-05-06 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of constant technological change upon our perception of the world is so pervasive as to have become a commonplace of modern society. But this was not always the case; as Wolfgang Schivelbusch points out in this fascinating study, our adaptation to technological change—the development of our modern, industrialized consciousness—was very much a learned behavior. In The Railway Journey, Schivelbusch examines the origins of this industrialized consciousness by exploring the reaction in the nineteenth century to the first dramatic avatar of technological change, the railroad. In a highly original and engaging fashion, Schivelbusch discusses the ways in which our perceptions of distance, time, autonomy, speed, and risk were altered by railway travel. As a history of the surprising ways in which technology and culture interact, this book covers a wide range of topics, including the changing perception of landscapes, the death of conversation while traveling, the problematic nature of the railway compartment, the space of glass architecture, the pathology of the railway journey, industrial fatigue and the history of shock, and the railroad and the city. Belonging to a distinguished European tradition of critical sociology best exemplified by the work of Georg Simmel and Walter Benjamin, The Railway Journey is anchored in rich empirical data and full of striking insights about railway travel, the industrial revolution, and technological change. Now updated with a new preface, The Railway Journey is an invaluable resource for readers interested in nineteenth-century culture and technology and the prehistory of modern media and digitalization.
