System for the control of the progression of several railway trains in a network
First Claim
1. A system for the control of the progress of a plurality of railway trains in a railway network, comprising:
- a plurality of on-board devices for disposition on respective trains for detecting the position of the train with respect to the track;
a plurality of means for transmitting and receiving communication messages for disposition on respective trains; and
a central station, said central station comprising;
a first storage means for the instantaneous storage of the relative positions of all of the trains in the railway network,a second storage means for storing the itineraries of each of the trains and the parameters of the railway network related to the speed range and the performance of the rolling stock in service, andmeans for receiving positional information from the plurality of trains detected by said on-board devices and transmitted by said means for transmitting and receiving, and transmitting at regular time intervals messages containing identification numbers of the trains in circulation in the railway network which are authorized to progress according to their itinerary after taking into account the positional information and the speed range parameters in said second storage means;
wherein the messages transmitted from said central station are received by said means for transmitting and receiving on the respective trains, and wherein said plurality of on-board devices each comprises means for recognizing the identification number of its respective train and means for controlling the stopping of its respective train which in the absence of the train'"'"'s respective identification number in the message received from said central station stops the train.

Abstract
Each train is equipped with an on-board device for detecting the position of the train with respect to the track and with a transmitter-receive communicating with a central station. The central station has an instantaneous storage of the relative positions of all of the trains in the network, storage of the itineraries of each train, the characteristics of the network related to the speed range, and of the performance of the rolling stock in service. The central station constitutes the organizing unit of the system and comprises a transmission at regular time intervals of messages containing the identification numbers of the trains in circulation which are authorized to follow their route, taking account of position information received from these trains by the central station and of speed range parameters contained in the storage. The device on board each train constitutes an execution unit of the system and recognizes the identification number of the train with which it is associated and controls the stopping of the train in the absence of the identification number in the message which it receives from the central station.
