| (54) | System for communication with trains on railway lines |
| (57) A system for detection of trains and digital communication with trains on a railway
line with at least one track, which track is divided into a plurality of successive
track segments, known as track blocks, and means for generating signals for detection
of or communication with the train being provided for each of said track segments
and receiving means allowing the track block to receive said detection and communication
signals generated by a train by active signal generation or change of the detection
and communication signals transmitted to the track block as well as means for processing
the detection signals or the communication signals received from the track block to
determine the operating or working conditions of the train and/or the track block
based on the changes found in the received signals with respect to the transmitted
signals and/or on the information contained in the communication signals transmitted
by the train and means for generating signals indicative of the operating or working
conditions of the train and/or the track block and for transmitting said status signals
to a central railway network control unit, known as central Interlocking System, which
is connected to said detection and communication unit and receives signals therefrom,
indicative of the conditions of the train and/or the track block, and transmits control
signals for detection of and communication with the train.
