Abstract

The system makes it possible to obtain a large flow of information and to increase the safety of railway traffic. Between a transmitter (3) disposed on the ground and a receiver (5) on board the railway vehicle receiving the information via the rail track short circuited by the axels of the vehicle, it comprises a frequency deviation modulated link. Applications: control of railway traffic safety.
