CRITICAL DEMANDS OF DATA TRANSMISSION BETWEEN TRAINS AND TRACKSIDE INFRASTRUCTURE

This article focuses on problems and implementation details of spot transmission and distributed communication systems in railway applications on the basis of the European Train Control System (ETCS). For spot transmission the “Eurobalise Subsystem” uses a passive transponder on the track called “Eurobalise” and a receiver unit at the train. Being still in the standardization phase, the “Euroloop Subsystem” uses a leaky coaxial cable as trackside antenna and a receiver unit at the train for distributed communication. In this work a system design is presented that comprises the authors experience with experimental implementations of the communication concept of both subsystems.
