The present paper puts forward a proposal for an extension to the conventional Grades of Automation (GoA) with a purpose of facilitating both dedicated operational and tactical assistance. The contribution aims to reintegrate the driver into the train driving activity with the new Grades of Operational and Tactical Automation (GOTA). The proposal of GOTA is intended to provide train drivers with the option of varying the level of automation over time. Furthermore, they will facilitate the breakdown of the assistance level into tactical and operational tasks. This breakdown will be according to the specific characteristics of the driver and a variety of criteria, taking into account human involvement and driving skills. The GOTA Selector which helps the driver to be optimally engaged while driving by adapting the GOTA to the specific needs is then planned.
