Started in 2005, the InteGRail project aims to improve the performance of railways by sharing information pertaining to the Operation Management, Rolling Stock Management, Infrastructure Management and Traffic Management. Such a wide scope requires a correct picture of which technologies are available in the railway industry, which technologies are available in other domains, and which main trends are to be considered in order to provide a valid answer regarding the project goals. Recent examples concerning technology obsolescence now require the railway industry to rely more and more on widely deployed / standard technologies (standard means already in used in other domains). Benefiting from Commercial Off the Shelf technologies, and ensuring by an engineering process that railway constraints are satisfied, is nowadays a common way of working. Engineering of communication systems is now made easier thanks to processes and tools that utilize techniques like simulation, modeling and automatic code generation. This set of techniques provides support for a solution that will address the issues of obsolescence, complexity, interoperability, interchangeability, independence from … A key result of the analysis of the InteGRail User Needs was the need for a greater complexity due to the increased interactions between the different actors in the railway domain. It was decided to go beyond the current InteGRail surveys by adopting an approach where the leitmotiv was to separate applications and technologies. For this, a framework was developed looking at all the constraints of the different actors, the existing solutions, other domains, new technologies and processes. Most of the information provided in this document concerning wired communication technologies has been taken into account by the InteGRail project. This survey can be used by any system architect for the design of embedded communication systems. Enjoy the reading and make comments to the authors. Thanks a lot.
