Reconstruction work of powerline Hoheneck-Herbertingen east of Eningen unter Achalm

It looks as if that old "classic" structure is to be replaced with a new one?

Ja, de lijn was oorspronkelijk de oudste 220/380-kV-lijn in Duitsland (Bludenz-Brauweiler, Nord-Süd-Leitung). Deze masten zijn van 1929 en worden daarom nu vernieuwd.

in 1929 was er toch helemaal nog geen 380kV? Zijn ze dan later geretrofit?

@Tom: yes, the section Rommelbach-Herbertingen of the powerline Hoheneck-Herbertingen is actually reconstructed. The line went in service in 1929 and one circuit of it is since 1964 in operation with 380 kV. See (in German): https://de.wikipedia.org/wiki/Nord-S%C3%BCd-Leitung
