Switching stations

Switching stations without power conversion, generation or feeding of overhead wires.

Central converter plants

In these facilities AC from the public grid is transformed into single phase AC and fed into traction current grid. At some facilities, power is also fed to the overhead wires. Conversion is made by machines or by electronic means.

Decentral converter plants

In these facilities AC from the public grid is transformed into single phase AC and fed only to the overhead wires. Conversion is made by machines or by electronic means.

Power plants

Border crossing powerlines

Points, where two powerlines for traction current crosses each other without interconnection

Substations

In these facilities electricity is transformed down from 132 kV or 66 kV to 15 kV. There is no conversion or generation of power.

Substations

In these facilities electricity is transformed down from 110/55 kV-level of OBB to 15 kV. There is no conversion or generation of power.

Central converter plants

In these facilities, AC from the public grid is transformed into single phase AC and fed into the traction current grid. At some facilities, power is also fed to overhead wires. Conversion may be performed mechanically or electronically.
