RAILWAY OPEN SYSTEM INTERCONNECTION NETWORK
The ROSIN project addresses the problem of interconnection between equipment located inside a railway vehicle or in different vehicles of a train, by means of a standard digital communication network, so as to achieve the following main objectives:
- interoperability at the train level, to allow inter-operation of coaches from different countries, especially for international trains performing cross border service
- interoperability at the vehicle level, to allow easy interchangeability of devices
- support to commissioning and maintenance phases and a general reduction in products life cycle cost
- openness toward external systems, to link on board systems with ground control and signalling systems
- performance improvement and introduction of new services
The ROSIN project aims at the validation of a complete open platform, that will be the base of a new generation of vehicles, consisting of an on-board network that is able to interconnect all various on-board systems and subsystems.
Taking advantage of a 5 years effort to specify a standard train communication network (TCN), being carried out within the International Electrotechnical Commission (IEC) by Technical Committee 9, Working Group 22, the ROSIN project has the ambitious goal to completely work out the final solution, that will closely address users requirements and will be validated and demonstrated extensively, using available technology, in a wide range of applications.
The project covers all aspects of the on-board networking problems, addressing key areas as passenger trains, including locomotives, freight trains and mass-transit (metros and trams). Communication and application requirements are considered, including maintenance needs, openness toward ground networks and suitable support actions for training and diffusion.

Remote monitoring for train maintenance
Railways consist of complex mechanical and electrical systems with hundreds of thousands of moving parts. In order to achieve reliable railway services, the equipment must be kept in good working condition with regular maintenance checks. The long lasting viable operation of railways greatly depends on early diagnosis of failures and despite the associated costs, the replacement of failing equipment early in its lifespan can be much more costly than the maintenance required. In addition, instances such as a stalled train may create immediate implications involving, for example, a railway block that can lead to timetable alterations with unmanageable consequences. Urged by these needs a European consortium developed ROMAIN a robust communication system for supporting remote monitoring and maintenance of railways. The consortium exploited a standard train communication network (TCN) which was developed by the International Electrotechnical Commission (IEC) for on-board interconnections and Internet protocols (TCP/IP) for off-board interconnections using a GSM radio connection. The system is capable of remotely and accurately monitoring the working status of any on-board device, part or equipment, offering not only on time but real time maintenance. Furthermore, it allows direct access to manufacturer's information providing a valuable supporting tool from/to any train wherever it travels. Taking into account all communication and application requirements, the ROMAIN system may be easily applied in a wide range of key areas such as passenger trains, including locomotives, freight trains and mass-transit (metros and trams). Reliability is the primary ingredient for successful railway operation. Since maintenance is the number one priority to ensure on-going reliability, it is anticipated that the new services, which are introduced with this system will substantially improve European rail performance and competitiveness.
