During the last three decades, a period roughly matching French transportation engineering history, important realisations have been implemented in four areas, namely safety, average speed, traffic density, and costs. Public guided rail transportation must remain competitive in this 21 century to face increasing quality, safety and cost requirements. These requirements were mainly supported by the development of advanced technology, notably with the introduction of automated train control. Our unit (ESTAS-Evaluation of Automatic Transport Systems and their Safety) is well placed to analyse automated train control devices, as we are not only involved in research but, have also been entrusted by the French Ministry of Transport, with assessing about 20 recent such systems. The progressive introduction of automatic train computerised control offers a hierarchy of driving modes ranging from manual operation to full automation. Three general levels were analysed: 1) Manual train control using safety devices for monitoring the driver's operation of the train speed and the passing of signals set at danger, 2) Automated Speed Control with driver and Cab signal display (based on line side devices, on board devices and track to train transmission system), and 3) Fully automated control, i.e. Automated driverless and Automated man less Control. This paper describes the basic concept like automation versus operator functions. Some recent French types of automated train control systems will be fact that Automated Train Control is not an end in itself, but must be justified in terms of the various benefits, beginning with safety.
