PSIcontrol controls traction current and railroad infrastructure in one system

Berlin, October 31, 2023 - PSI Software SE has been awarded by the Schweizerische Südostbahn AG (SOB) to deliver the control system PSIcontrol 4.9. This will monitor and control all systems in the areas of catenary and rail infrastructure in one central system in the future.

SOB operates power and switching stations on its route network from Romanshorn on Lake Constance to Arth-Goldau in Central Switzerland to ensure the traction power supply. In addition, it runs technical systems for monitoring the various railroad subsystems at the stations.

In the future, PSIcontrol will map, control and monitor the operation and maintenance of the track network for the areas of alarming, catenary and infrastructure in a central system. This will provide the management of the traction service with an overall view for instance of messages or alarms, in order to initiate suitable measures if necessary.

The integrated module for monitoring also provides an overview of the connected infrastructure systems in order to avoid interventions caused, for example, by sudden changes in the technical systems and to plan maintenance work. The project is scheduled to go into operational service in September 2024.

The 111 kilometer long rail network of the SOB is characterized by numerous engineering structures; 19 tunnels with a total length of 7 km as well as 192 bridges, viaducts and underpasses and overpasses - including the 99 meter high Sitter viaduct, the highest railroad bridge in Switzerland.

The PSI Group develops software products for optimizing the flow of energy and materials for utilities (energy grids, energy trading, public transport) and industrial companies (metals production, automotive, mechanical engineering, logistics). As an independent software producer, PSI has been a technology leader since 1969 for process control systems that ensure sustainable energy supply, mobility and production by combining AI methods with industrially proven optimization methods. The innovative industry products are sold both directly and via the cloud-based PSI App Store. In fiscal year 2022, PSI generated annual sales of just under 250 million euros with more than 2,200 employees in 17 countries.
