Integrated Control System (iBS)

As a part of DB Netz AG‘s new system architecture in the area of the control and signalling equipment (LST), Scheidt & Bachmann has developed the integrated control system (iBS). It enables the manufacturer-independent operation of modern DSTW and ESTW via the standard interface SCI-CC. The integrated control system does not contain any safety-related functions and integrates all applications required for the DB driveway service in a uniform look & feel.

The transparent connection of railway interlocking systems from different manufacturers is provided by the so-called iUZ. In addition to adaptation to the standardized SCI-CC interface, it also bundles important functions such as train describer, automatic route setting and documentation. For the railway interlocking system type ZSB 2000 it also enables the connection of all productive installations/systems in the field to the iBS.

The iBS offers significant improvements compared to the classic control systems:

Attractive workplace

  • Ergonomic, standardized control station with large 50‘‘ monitor
  • Single sign-on and integrated control of LST, TC, MAS, and dispatching
  • User interface according to web standard (window technology, drag & drop)
  • Manufacturer-independent control of the DSTW/ESTW via iUZ standard interface SCI-CC
  • High ease of use thanks to a wide range of support functions such as operator profiles and configurable time-of-day-dependent illumination of the screen background

Economical efficiency and future-proof design

  • Standardized display and input safeguarding procedure
  • System concept without specific requirements on IT components
  • Use of standard IT components („Commercial-of-the-shelf“ COTS)
  • No proprietary, manufacturer-specific hardware
  • Short release cycles using agile release processes
  • I nvestment protection through iBS variants with migration capability

Scalability, operational flexibility, migration

  • Concept to equip railway operating stations (BSO) with 6 to 20 operator stations
  • Switching from one to another operator station as required during operation
  • Variants for adaptation to different application scenarios, e.g.:
  • iBSlocal – enables operation in the absence of a connection to the central services like bbIP and directory service
  • iBScompact – for space-saving accommodation, independent of central services, for smaller production areas
  • Simple migration of iBSlocal and iBScompact into a BSO due to interface compatibility
  • Variant and migration concept allows fast iBS introduction and ensures investment sustainability.

Since its piloting in 2020, the integrated control system iBS has proven successful operation in Germany at

  • ESTW Harz-Weser
  • DSTW Kleve, Bedburg-Hau, Goch, Kevelaer, Nieukerk, Kempen
  • ESTW Sondershausen
  • SIMIS D in Göttingen
