This paper presents the possibilities for using currently installed interconnection cables for extended intra-train communication purposes and proposes a CAN-based communication solution for the problem. The implementation of such a communication technique raises feasibility issues due to the non-standard physical media and the non-fixed network topologies, such as, the determination of an achievable bandwidth, the dynamic termination of the network and the enumeration of units. As a basis of on-board passenger information and telemetry solutions for the operator, this solution could be a cost effective way to improve the quality of service of rail transportation. This paper describes the specialties of the vehicular environment and the proposed network model; it then presents a network lookup algorithm for automated enrolling and ordering the needed train units. Laboratory and field measurements are presented to validate the feasibility of this solution.
