Integral control and information system

from Wikipedia, the free encyclopedia
Each operations control center equipped with Iltis controls a certain part of the rail network. It only reports the train locations to the neighboring operations control centers.

The integral control and information system , abbreviated as Iltis , is a control and information system developed by Siemens Switzerland that allows a largely automated operation of a railway line .

Polecat from the Transports de Martigny et Régions in Vernayaz to control the Martigny-Châtelard railway line .

This includes the remote control of several interlockings , the monitoring of operations and the control of the passenger information systems in the stations . A clear screen surface conveys the information for the large-scale management of railway operations, whereby, if necessary, special processes at individual stations can be observed and remotely controlled with a zoom function. The dispatchers are relieved by the automation of operator actions . The system also supports the dispatchers in the event of operational disruptions, because thanks to the logging , all events can be reconstructed afterwards. The VMS operating system was originally used for the Iltis , but it now also runs under Windows .

The first system went into operation in 1994 in Bern's main train station. It initially controlled two signal boxes, those from Schüpfen and Münchenbuchsee on the line to Biel. The circle later expanded to include 18 remote-controlled signal boxes on the SBB routes towards Zurich (all up to and including Hindelbank), Biel (to Suberg), Freiburg (to Flamatt) and Thun (to Wichtrach). In 1995 Bellinzona received a further developed Iltis variant which, in addition to remote control of the signal box, also enabled train tracking and automatic train steering. This system quickly spread throughout the entire SBB network; most recently there were around 25 remote control centers. In the slipstream of the federal railways, numerous Swiss private railways also rely on the Iltis technology, as do ÖBB in Austria and railways in Hungary, Slovenia, Malaysia and Slovakia.

Polecat N.

With Iltis N, the functional level for controlling the interlockings (cells) and the operating level with the workplaces are separated. The entire railway network can be accessed from every operator station.

With the advancement Iltis network (Iltis N) is set via an IP - network , a group of several controlled by Iltis routes controlled from one location. To this end, several railway control centers can be networked with one another across the region. The basic principle of Iltis N is the separation of the functional level and the operating level. The functional level consists of so-called cells, which are responsible for controlling the signal boxes and automatic train routing . The operating level is formed by a few "operating clusters" with which the individual cells can be operated. The original operating limits are thus broken, because the entire railway network can be accessed from every operator station . Should a workstation in an operating cluster fail, any other workstation can take over its function. Interfaces allow access to the centrally stored timetable data. Iltis N allows further rationalization compared to Iltis , as fewer operations control centers are required in the final stage .

Since 2017, the Gornergratbahn (GGB) has been using the Iltis N control system for the first time worldwide on a “ cloud ” basis. The control technology overriding the interlockings is located at Siemens in Wallisellen near Zurich and is connected to the dispatcher workstations in Zermatt via two redundant data lines from Swisscom . Deutsche Bahn purchases all of the control technology functions under license without having to purchase the required hardware and software . The maintenance and repair work is carried out at Siemens without a technician having to travel to Zermatt. The license costs roughly correspond to the investment and operating costs of a conventional system.

Iltis N is currently in use at ÖBB in three of the five operations control centers, those in Vienna, Villach and Innsbruck. In the BFZ Linz and Salzburg, the "GRAULI 2.0" system from Thales takes on this task.
