Open, flexible Ethernet infrastructure for SBB

In order to improve the service for passengers further and to make operating processes even more efficient, Schweizerische Bundesbahnen (SBB) decided to introduce new, state-of-the-art systems for customer information, video monitoring and counting passengers that are based on an open, flexible Ethernet infrastructure. One partner for this project is Hirschmann. The wagons will be linked via HIPER-Ring and IP67 switches.

The "SBB vehicle applications" program combines the following applications on a technical platform as an open solution:

  • Customer information system (CIS)
  • Video monitoring (Video)
  • Automatic passenger counting system (APC)
  • Vehicle platform (VP)
  • Multimedia bus (Ethernet)

Hirschmann's job is to provide the necessary communication infrastructure for these applications inside the trains based on fast Ethernet. Ascom (Schweiz) AG is the contractor for both the double-decker commuter trains and the modernised lowered floor commuter trains projects and will be the main contractor for ZUKO (train communication for DPZ's) and multimedia bus (MPZ). The communication infrastructure will enable additional applications to be integrated easily at a
later date. The open platform must be able to be used both for regional and long distance vehicles.

Project parameter

  • Project duration:
    - DPZ: 2007 - 2009
    - MPZ: 2007 - 2013
  • Number of switches:
    DPZ project with 117 train compositions:
    – 702 OCTOPUS 16M
    – 117 OCTOPUS 24M
    MPZ project with 113 train compositions:
    – 264 OCTOPUS 8M
    – 510 OCTOPUS 16M
  • Additonal Hirschmann services:
    - Devising the initial design
    - Supporting the design with detailed network planning and determining the specifications
    - Configuration support (basic setup)
    - Training for system suppliers (ASCOM) and end customers (SBB)
    - Auto configuration adapter preconfigured at the factory
    - Commissioning support (on site)

Solution

  • Two IP67 protected switches with M12 connectors for each carriage
  • The complete current train sequence of the comprehensive HIPER-Ring
  • Intelligent infrastructure with independent detection of the current train topology, i.e. the order of carriages and the direction they are travelling
  • Open communication interface for the topology query
  • Preconfigured auto configuration adapter for simple commissioning and reliable faulty device replacement
