Or, besides the tracks bonus, part two. This wind turbine in the industrial area between the Westbahn and the parallel highway in Böheimkirchen was one of the first commercial installations I saw.

The hen farm is on the edge of a small residential district. At this distance, I couldn't hear even a swoosh from the turbine, but that may have been due to the rain.

From what I found on-line, it is operational since 1996, and is a Seewind SW 20/110 (rotor diameter 20 m, maximum power 110 kW, hub height 31 m). If I a not mistaken, southwest German manufacturer Seewind somehow became part of Danish maker NEG-Micon which itself merged into Vestas.
