Powerlines north of Hoheneck substation (visible at the bottom left corner). Hoheneck substation is situated north of Ludwigsburg and since the 1920ies in use. From Hoheneck substation to Rommerskirchen substation, the first 380 kV-link in Germany was realized.
The large powerline in the foregound runs from Wendlingen substation to Pulverdingen substation.

Powerlines between Sindelfingen-Maichingen and Grafenau-Döffingen at night. The towers with three crossbars and six conductors belong to the powerline Hoheneck-Herbertingen and were built in 1929, the tower with three crossbars and twelve conductors is part of the powerline Pulverdingen-Oberjettingen and was erected in 1971 and the towers with a single crossbar and four conductors are part of the single-phase AC 110 kV powerline Zazenhausen-Eutingen of the German Railroad Company and were built in 1974.

The powerline Hoheneck-Herbertingen was originally a powerline with two 220 kV-circuits. In 1964, one of its circuits was switched over to 380 kV.
As at most double-circuit lines each circuit occupied one half of thhe tower.
However the towers of the powerline Hoheneck-Herbertingen are not very suitable for 380 kV as they can only carry double conductors and only shorter insulators than that used on other 380 kV-lines.
The result was especially at rain high audible noise.
A few years ago, one decided to give up the scheme with one circuit on each mast half and changed the scheme to that shown on https://commons.wikimedia.org/wiki/File ... tingen.png . The result was less noise and a greater clearance below the line.
As the line was rebuilt between Rommelsbach and Herbertingen from 2019 to 2021, one decided to use the scheme with one circuit on each mast half for the renewed line, while at the old section from Hoheneck to Rommelsbach the 380 kV-circuit was switched over to 220 kV and the 220 kV-circuit was sut-down with the wires remaining in place.
However the change from the scheme shown on https://commons.wikimedia.org/wiki/File ... tingen.png to the scheme with one circuit for one mast half does not take place at the beginning of the renewed section, but 5 towers before between the straners with the numbers 218 and 219.
The following picture shows Tower 218. In the span-field between Tower 218 and Tower 219, the change took place as you can see on the picture.

Three powerlines east of Mötzingen. The line in the foreground is the 110 kV-line Oberjettingen-Rottenburg-Tübingen, the branch runs to Mötzingen substation. Note the two communication cables, which are fixed like garlands on the ground conductor and on an auxiliary rope.
The following line is the 380 kV-line Oberjettingen-Engstlatt and the line in the background is the 110 kV single phase AC powerline Zazenhausen-Eutingen of the German Railway Company.
