Prior to the first English edition, substantial parts of the book were revised and adapted to include international overhead contact line designs. There were no comparable works available and the book enjoyed wide distribution and attracted great interest, even in non-German-speaking countries instigating the need for translations in other languages. Both had essential roles in the production of the German edition. Peter Schmidt, died unexpectedly in 19, respectively. The co-authors of this book, Professor Dr. The first edition was out of print quickly, so a second, revised edition was published in 1999. Preface to the first English edition The first edition of "Fahrleitungen elektrischer Bahnen" (Contact Lines for Electric Railways) was published in German in 1997 by B.G. I would like to congratulate and thank the authors and publisher for their initiative by offering this important work to tlwir professional colleagues all over the world I am very pleased to report that the compendium of knowledge provided by this book, "Contact Lines of Elc\ctric Railways", was a great assistance in fulfilling this task. The parameters, which are to be standardised in this way, have to be chosen carefully, taking technical and economic factors into consideration. In this process, "Technical Standards for Interoperability" which establish binding rules on the essential parameters, have been drawn up inter alia for the energy supply sector, where contact lines are dealt with specifically. In this context, I would like to draw the readers' attention to the evolving technical and operational harmonisation of European railway companies spurred on by the EC directives on interoperability. The mechanical and the electrical parameters of contact lines, structural design solutions, project planning, constrnction and operation, including maintenance, are also discussed in detaiL In addition, the lists of available relevant international, European and national standards, as well as the regulations of railway operators and railway associations included in the appendix of the book are very useful. The interaction of current collectors and contact lines and the issue of interference with railway-owned and third-party installations are dealt vvith in special chapters. The structure and contents of this book reflect this systematic approach: It contains a detailed description of all existing alternating-current and directcurrent systems, the basic requirements that these impose on contact lines and the essential characteristics of the two basic designs: overhead contact lines and contact rails. A thorough analysis of these requirements and corresponding satisfactory design measures are prerequisites for reliable and economical operation of contact lines and of railways in general. The contact line designs must be adapted to the respective technical and operational requirements of the different railway electrification systems, the diversity of which has broadened considerably especially with the development of high-speed railway traffic. It is the interface between fixed installations and moving energy consumers, i. A contact line is an essential component of all electric railway traction energy supply systems. C t Lin f I ti ii Planning Design Implementationįoreword The publication of "Fahrleitungen elektrischer Balmen" in English gives the international railway engineering community access to a work which, since its first edition in 1997, has achieved the status of a standard reference in German-speaking regions.
