Preface:

Having read this extraordinary compendium of electric traction, inevitably, I recall the lessons that I attended 30 years ago at the “Politecnico di Milano” in the classrooms within the Department of Electrotechnics, as a student among others of Prof. Dario Zaninelli. Just by reading this text, I have now realized what it was like, then how it is today, to use an organic and complete description of the many and different components of an electric traction system, from the electrical sub station to the onboard systems, a “Testo Unico” of traction electricity. What strikes the reader is the clear terms of clarification, inevitably resulting from a profound knowledge and expertise of the authors on the subject matter. Clarity that allows you to meet at different levels of curiosity and learning as the

articulation of the text lends itself to easily navigate in system descriptions, reconstructing both the historical evolution and the different technological solutions adopted in different countries around the world, to drop both vertically and very analytically into the study of the subsystems and the operation of all components. At the same time, this text will be useful to those who, like myself,

have taken advantage of the work of the authors for a useful and organic review of the subject and for the designers and researchers to work to make electrical traction ever more efficient starting from state of the art.

It is striking, and it is one of the reasons for the remarkable size of the work, including the incredible number of technical solutions adopted in different countries, sometimes deliberately preventing interoperability, for example, for reasons of war, as it was the case in Europe in the first half of the twentieth century. As the UIC chairman, I declared the need for interoperability between rail networks, which UIC supports the production of standardization leaflets. In addition, I emphasized for continuous research to improve the overall performance of traction electrical systems, as it will guarantee in the future both the extension of high-speed networks and the electrification of many more diesel lines. UIC, together with its members, have been committed to increase energy efficiency by 2030 and to reduce emissions per unit of traffic by 50% compared to 1990, and to further improve them by 2050. It is therefore my pleasure to present and support this compendium that will help the railways of all countries of the world to integrate and to grow even more, in a responsible and clean manner.
