INTRODUCTION
Over the past forty years, electrical engineering and electronics have undergone profound changes in railway applications, both in terms of equipment and its integration into the "railway system", with economic, energy and environmental issues at stake, not forgetting the fundamental requirements of reliability and safety.
It is interesting to measure these developments in the three key areas of electric rail traction:
fixed train power supply systems ;
Powertrains, which provide on-board electromechanical conversion;
control-command equipment, formerly known as "signalling equipment", based on less sophisticated principles and designs than at present.
