  • the method for controlling 100 and the control system 4 allow reducing data exchanges, because the attributes SEC, DEV are only transmitted to some of the local controllers 12A, ... 12G, according to the subscription data SUB.
  • the amount of data to be transmitted is further reduced and/or simplified.
  • the event-based communication is in particular advantageous compared to a method in which data concerning track sections is transmitted in a cyclical way, i.e. in predetermined time steps, because for example the number of messages is reduced according to the method 100.
  • the method and system according to the present disclosure allow obtaining a high availability time of the control of the railway track 2.
  • the track sections T1 to T8 controlled by local controllers 12A, ... 12G other than the modifying controller(s) remain operational, as the central data system 8 is not interrupted during modification of the local controller(s) 12A, ... 12G.
