This international anthology presents case studies of historical and contemporary transformations of large technical systems such as railways, telecommunications, electricity, and automobiles. The authors, working at the forefront of historical and social science research on the dynamics of large technical systems, analyze how and why these systems undergo change. Because of their important roles in contemporary society, large technical systems such as railways, airlines, road systems, telecommunications, and electric power network share drawing considerable academic and political interest. In this collaborative study on processes of change in large technical systems, the contributing authors present historical and current case studies of transformation within these systems. Working at the forefront of historical and social science research on the dynamics of large technical systems, the authors specifically analyze how and why the systems undergo change. In some cases, new technologies are solving old problems and presenting opportunities for system growth. In other areas, new regulatory approaches have brought competition and deregulation, often posing challenges to system builders. The authors also show how the breakup of national boundaries and new corporate strategies for global management of technology are transforming systems in ways that will have significant impacts on all consumers
