Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Last week I worked along the Budapest-Vienna railway line, which crosses a windy plain full of wind turbines. Who can identify the types?

1st Photo: Can't tell the dimensions, but the two wtih green-blended tower bottom tower sections are definitely Enercon, guessing E-66 or E-70. Larger turbine appears to be Vestas, but can't be certain from the photos.

2nd Photo: guessing Vestas but unclear on model (V-80?). Painting seems to be local developer or utility. Could also be REpower or Nordex. i'm stumped.

3rd Photo: ??? But always good to see turbines by railroads.

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

btw, the Enercon's have that different shape as they have no gearbox, with the rotor directly feeding the larger low-speed generator, hence direct-drive.

What's the energy efficiency loss with a gearbox; why aren't all turbines direct drive?

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.

Danke, DoDo, wish i could have caught the workhorse MM82s. Actually been a while since i've seen one.

Enercon E82s

The stanchions look rather old tech, how old are they?

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.

1st picture: 2 Enercons and one Repower 2MW. The Enercons have the new blades, so it's the 2MW, probably the E82.

2nd pic: looks like the Repowers, but it's hard to say - maybe the Nordex?
