In this paper, an object-oriented approach for Automatic Train Operation (ATO) is discussed in order to compare it to the traditional event-oriented software developed and now used on most of these kinds of systems. In the last decades, the object-oriented approach has been used in a growing number of applications because it supplies flexibility and understanding easiness for the applications. The UML (Unified Modelling Language) supplies many tools for project analysis and documentation. The various UML diagrams allow many points of viewing the project: the static dimension (class diagrams), the dynamic dimension (sequence and state diagrams) and the method dimension (data flow diagrams). The ATO systems, however, had their development aligned to microprocessors development. So, the ATO software has born on assembly form, because ATO
