3rd: They look like they have the same broad, round nacelles as the German ones in the first picture.

Friends come and go. Enemies accumulate.

The background ones in the 1st & 3rd photo: two each from the same farm of 5 Enercon E-70 units. One of them (the one on right in the 3rd photo) is just beside the tracks, once we stopped right there, and it was the first time I heard turbine noise separate from wind noise (from this gearless unit, only aerodynamic noise, a swoosh like a landing airplane but much more silent).

The foreground one in the 1st and the three in the 2nd photo: I think those are REpower MM82s from a farm of 12 turbines. The logo indeed belongs to developer Wien Energie.

There were Vestas and Gamesa units in the area, too, but I couldn't catch them on zoomed-in photos.

About 15 years old. I'm not sure about what looks old tech, but the stachions certainly look light and thin compared to what you see on high-speed lines (or new/renewed Austrian lines with their massive concrete poles). Then again, this is a 160 km/h line, they don't have to be all that strong.
