Railway companies operate their own electricity networks to supply their railway system with electricity. The requirements for monitoring and control (transmission and catenary level) are on one similart to those of regional network operators. On the other hand, railway-specific constraints must be considered and the corresponding functions be implemented.
Examples of this are:
After supplying all central control centers for catenary electricity and a central support tool (PSIcommand) for Deutsche Bahn, several other major railway companies have awarded high value orders for railway electricity control systems to PSI.
