Industrial Ethernet for Ancona-Bari railway line

450_249_Ancona

 

Italian public company RFI, part of the Ferrovie dello Stato group, is responsible for the efficient operation of railway lines. Part of this responsibility is to ensure that the railways are using the latest state-of-the-art technology. When it came time to revamp the Service System network between Ancona and Bari (part of the “Adriatica” line), RFI chose industrial Ethernet, as the highest performing and most future-proof communication technology for installation in critical environments. AlHof, Italian partner of Hirschmann™, supplied equipment and expert knowledge for the project, which included three tunnels (San Giovanni, Diavolo, and Vasto). The project was realized by the specialist system integrator Siscom.

The communication network realized by Siscom for the San Giovanni, Diavolo, and Vasto railway tunnels fully satisfies the fundamental criteria for transport systems: reliability, redundancy, and availability. By using Hirschmann™ switches, Siscom was also able to provide dependable cutting edge products, to the complete satisfaction of their customer.

Project parameters

  • Maximum tunnel length: 9 km
  • Minimum tunnel length: 6 km
  • Distance between niches in the tunnel: about 250 m
