<p>With the emergence of new modes of rail transport, it is essential that an ergonomics and human factors study is carried out to ensure that the drivers’ needs are fully considered during this transition. Several studies have highlighted the benefits of HUD’s in transport domains, particularly in improving the visibility of key information and reducing the time that drivers need to look away from the train and its environment. However, the implementation of such interfaces is also a challenge, as technological solutions can be complex and must meet high safety standards. This article investigates the possibility of integrating head-up displays (HUD’s) into the design of driver’s cabs for new-generation trains, i.e. very light trains operating on small rural lines. The work is based on a dual approach: a review of the relevant literature and an in situ analysis of train driving activities, with the aim of understanding the requirements of train driving activity, identifying information needs and assessing how HUD’s could support drivers in their tasks. We firstly examine the advantages and disadvantages of HUD’s and highlight the potential contributions of HUD’s in a new generation train. We then analyse train driving activities to identify the main information requirements and examine the constraints imposed by existing railway standards on the integration of HUD’s. Finally, we propose design recommendations and preliminary visual interfaces adapted to the specific needs of driving very light trains.</p>
