SNCF plans to introduce the automated train operation (ATO) system into the manual driving trains to make the train driving experience more efficient, eco-friendly, and precise. With this transition to automated trains, the organizational and human factors and railway safety must be re-examined. 

Preliminary Risk Analysis studies have been performed at SNCF but they are theoretical and have not been validated by simulation.

As a contribution to the state of the art, we propose to use the PRODEC method [1] to achieve a safety-orientated human-centered design. This method is based on the comparison between declarative and procedural scenarios.

To implement the method, one must first construct and select scenarios. This is the main contribution of this paper. We propose to present our methodology and results based on:

1) The analysis of the incidents that occurred in the French railway system during the past years (https://ressources.data.sncf.com/explore/dataset/incidents-securite/information/?sort=date) with their classification, occurrence, and severity.

2) Expert judgement. Today’s train drivers are trained by performing different scenarios on simulators and in real driving cabins. The experts have designed the procedures to guide railway operators in different situations. 

By doing so, we aim to define the human and organizational factors or the technical elements which have significant impact on system security and to build the most relevant scenarios.
