Markings on the southeastern corner of this pylon. "Stern-Pkt." means neutral conductor.

North of Grossgartach Süwag substation one can see this tower. It was once the first pylon of the 110 kV-line from this substation toward Bad Wimpfen and is now - after the removal of the crossbar - a nesting place for birds.

The 220 kV-powerline Rheinau-Hoheneck crosses west of Grossgartach Süwag substation the railway line between Heilbronn and Bretten with a strainer on each end of the span over the railway line. The southern of these strainers, which carries the designation "Anlage 4507, Mast 44" is very remarkable as it was converted from a pylon with three-conductor arrangement in one with two-conductor arrangement in order to get a greater clearance.
For this purpose one of the supports between the lowest and the medium crossbar was removed and installed between the body of the tower and its lowest crossbar. Then a second conductor support point was installed on the medium crossbar.
However in 2003 one circuit of the line was shut-down and the two lowest conductors were afterwards removed, so the conductor arrangement on this tower is the same as on the others of the line.

The 220 kV-line Hoheneck-Beerfelden, which was demolished between Leingarten and Hoheneck in 2004, used for the undercrossing of the powerline Rheinau-Hoheneck near Leingarten two low portal pylons with the designation "Anlage 2332, Mast 549" for the southern and "Anlage 2332, Mast 548" for the northern one.
After 2004 these portal pylons were used for the realization of a 220 kV-branch to Grossgartach-Transnet substation from the powerline Hoheneck-Rheinau. Herefore the conductors of this line weres interconnected with them on the portal.
However in 2020 the former 220 kV-line to Beerfelden was converted in a double-circuit 110 kV-line, which starts at Grossgartach Süwag substation.
The portal pylons went obsolete, but remained interestingly standing.

Portal pylon "Anlage 2332, Mast 548" under the powerline Grossgartach-Beerfelden, which was originally a line with one 220 kV and one 110 kV-circuit and is now a double-circuit 110 kV-line. Left from this line one can see the 220 kV-powerline Rheinau-Hoheneck.

Three 380 kV-powerlines depart from Grossgartach Transnet substation in northern direction, which run to Heilbronn power station, Kupferzell substation and Hüffenhardt substation. The line to Hüffenhardt substation runs on the pylons on the left, that to Kupferzell substation and Heilbronn power station runs over the pylon in the middle, where the line splits: the line running to the right edge of the picture runs to Heilbronn power station, the other to Kupferzell substation.
The third line, which was built in 2022 is unused and ends on a strainer with a single horn on the top. Obviously it was not possible to install the other on its top as it would have come too close to the conductors of the pylon, where the lines to Kupferell and Heilbronn power station splits.

I recently visited Großgartach Substation in February 2022, when some old 220 kV lines have been dismantled. Interestingly the low portals from the former 220 kV are still standing...

Somewhere here the question came up about the old one-circuit 110 kV powerline between Karlsruhe and Pforzheim. I can tell you, this is NOT the line from 1917 but indeed a very old line (I think 1920s, when the following powerline to Hoheneck was established). If you want, I can take pictures of this line and their transmission towers as it's not far away from me (anymore :grin: ).

At the German Digital Library (Deutsche Digitale Bibliothek) there are a lot of images taken during contruction or widening of highways in the state of Baden-Württemberg. And on a lot of pictures you can find old lines of former Badenwerk or EVS, which don't exist anymore. Check it here: https://www.deutsche-digitale-bibliothe ... C5USK7UTIR Near Ettlingen, once two one-circuit lines similar to the one towards Pforzheim crossed the Highway A5. (https://www.deutsche-digitale-bibliothe ... BL7TTAOSHM) Today there's a 220/110-kV combination line which surely exists since the 1970s. So I think the old line towards Forbach doesn't exist anymore since quite a long time.

BTW: There one used to be an old substation named "Scheibenhardt" somewhere west of Rüppurr. I think this station was removed and replaced by Daxlanden substation in the 1960s.

What happened to the pylon on the right, one of the wire horns is missing. :o

Sure!

To be honest - If I could choose what is placed in front of my house - an old, rusty pylon from the 1920s or a bunch of new TenneT 380 kV power lines - I would choose the old one!
