I wrote in my diary recently that I wondered if the power line going through Mittelstadt and Oferdingen will be removed.
Actually a farmer had told me that back in February so I wasn't just wondering.
Now I found a press release from the regional oligopolist EnBW:
http://www.enbw.com/content/de/presse/pressemitteilungen/2009/04/PM_20090420_cu_ys01/index.jsp
So in July, they're going to remove the other part of this line because they have upgraded other parts of the grid to 380 kV to completely remove the 220 kV layer in the long run.
OK, so no need to map this line any further...

It was built in the 1940s and actually runs at 220 kV. I'd tagged it as 110 kV as I didn't recognize it as 220. They call it the Schwarzwaldleitung which would be the "black forest line" in English.
I also wrote that I still wondered what TRS stands for. Well, actually I had photos of signs on the masts saying "TRSNG-WDLNG" and that doesn't leave too much room for interpretation what it means - yes it does stand for the town of Trossingen. You just need to look at them, Markus. ;-)
It continues on until Tiengen, the press release says, which is also the end of a branch of the Nord-Süd-Leitung.

What they don't say in their press release is that the line wasn't used as a whole for some time - at least long enough to put plates on the towers which showed that near Mittelstadt, WDL-MEZ left this route and the (probably original) TRS-WDL was (and still is for a few more weeks) put on it.

So there's still nothing better than to go out and see for yourself what it looks like before putting it in OSM. ;-)
OSM currently shows the state of the line at least of June 13 and I'll certainly observe the removal work as this is something that you don't see every day. I already missed it for the part between Wendlingen and Mittelstadt. After all, the line's been there for more than 60 years now.
