This paper gives a closer look to the subject of the conversion of a conventional metro line into a fully automated operation without interrupting or disturbing the service. In the introduction, we present the Line 1 Automation project as one of the principal aspects of Paris metro’s network modernization plan announced by the Régie Autonome des Transports Parisiens (RATP). Next we give an overview of the present line 1 and illustrate the decision key elements for choosing it as a target of a fully automatic operation. The following section describes the development of the line 1 model and shows the results made so far. Finally, we expose the conclusions of the present work and the outlooks of the line 1 automation project. Keywords: Paris subway network, fully automated operation, safety, simulation. 1 Introduction Three phases have marked the RATP history. The period 1900-1935 was the birth of the Paris subway. The period 1955-1975 has known the first modernization wave with the technology breakthrough of the operational control centers (OCC), the automatic driving, the controlled manual train driving (CMC) and with the new generation of the rolling stock. The period 2005-2020 shall see the second modernization wave. A 50 years cycle gives rhythm to these evolutions. So the new phase engages the Paris subway for the next decades. The functional and technical bases of the new modernization program have been defined by the RATP on April 26th, 2002. Being oriented towards the new
