Tons of information here on the German class-52 2-10-0. Quite interesting stuff on these locomotives, found everywhere in Europe and other surprising places. The Army brought one to the US, but it was scrapped in the 1950s. Another is exhibited in Japan. Note the Norway section. One was hidden there in an abandoned tunnel, like that NYC Hudson we know is in the coal mine..

There is one kondenstender left in Germany. It was used in experimental stationary service. I would post a picture if I knew how.
