The impact of social-economical changes lead to the necessity for polyvalent service and technical staff. Technological evolution has made systems more complex, intelligent and interactive. On-board systems are therefore required to support higher comfort, increased availability, better maintainability, reduced life-cycle cost and increased efficiency. Safety, availability, reliability, maintainability and life cycle costs of transport systems are directly determined by the efficiency in fault diagnosis throughout the life cycle. Improved efficiency in operational diagnosis comprises; ? Significant increase in the level of diagnosis automation. ? Significant increase in the coverage of problems. ? Significant increase in the accuracy of diagnosis by tuning symptoms, additional tests and actions. ? Ensuring guaranteed response times for critical on-line diagnosis situations. To cope with the mentioned evolution, a Central Advice System (CAS) for rolling stock (trains, trams, underground, light-rail transport systems, etc.) is under development as a decision support system for drivers, maintenance personnel and fleet managers. This development takes place within the framework of the European research and development project BRIDGE (ESPRIT Project 22154). BRIDGE specifically aims at real-time diagnosis of very large technical applications. The overall go
