This infrastructure includes a network MPLS; first and second groups of access points associated with each section of the track; first and second modems, on the train, communicating with access points of the first and second groups. The network includes pairs of local switches, each associated with a section of the track and including first and second local switches for communication with, respectively, the first and second groups of access points of the associated section, and first and second central switches, the switches being in series with one another and implementing a service for defining paths between each central switch and each local switch so the path between the first central switch and the first local switch of a pair and the path between the second central switch and the second local switch of this pair correspond to separate portions of the ring formed by the network.
