Well done Alte, another fantastic report.
I discovered Sinsheim in the late 80s and a few years later was organising coach trips there. The photo is from a 92 guidebook. To get the best you need to visit in the winter as quite a few of the exhibits are on loan and are out on the road in the summer. Havn't been for a long time now and wonder if they still have the Trains suspended on steel cables. Sinsheim and the German Museum in Munchen are have to see places. I have just returned from my annual South of France, Italy, Switzerland, Germany and Belgium trip and will post photos when the cold weather sets in
If you are interested pm me your postal and I will send you the 92 guidebook for a read.
