Right from the beginning, the power cables for public supply and those for the railway supply were mounted on crossbars above the catenary on the wire gantries. Even today – although the public supply has been changed to three-phase at 50 Hz – about 21 km of community power lines are still in service. However, in the 1970s and 1980s, a separate 20-kV line was built between Loich and Frankenfels by the power supplier EVN, which is responsible for public power supply in the area, leaving only the 27-kV line for the railway and the catenary itself on the wire gantries.
