Deliverable D 6.1 User and functional specifications for multi-purpose resilient adaptative on-board telecom networks

Train services is mainly composed of two main areas, namely Train Control and Monitoring System (TCMS) and On-board Multimedia and Telematics (OMTS). TCMS is responsible of the integration of train functionalities such as braking, commands and others. Whereas OMTS conveys users and operator information. Telecommunication infrastructure used by Train Communication Network (TCN) to convey the train traffic is currently very simple and based on a wired system. Due to cables maintenance and diagnosis cost, the efficiency of this system should be greatly improved to enhance the functionality of both TCMS and OMTS domains.

Hence, the New Generation Train Communication Network (NG-TCN) has emerged as a major innovation introducing a wireless architecture as an enabler to enhanced automation, flexible train management and increased railway capacity, in addition to leveraging the virtual coupling concept. NG-TCN targets replacing completely or partially the wired communication infrastructure by wireless solutions and technologies.
