Guys, thanks for the overwhelming response to this post. This picture is truly a mystery for me. This was in of one of my first books about WW2 Planes/weapons, the book certainly looks well used by now!
Regarding the picture, I know about attacks on trains during the Norwegian campaign april-june 1940, but attacks AFTER this date on rolling stock in Norway was pretty scarce, or I'am wrong here? The point is that traveling in Norway (very generalized) excluding Coastal Shipping after 1942/43 and train riding in march-may 1945 (sabotage actions) was pretty safe, even for German soldiers. But I can't find any information from the Norwegian Railways (NSB, the same organization then as today) that such a attack was done on their Trains. Could the caption be wrong?
I will post a large high res. picture when I get to my study appartment since it will take ages with my dialup connection here
Regards,
Tormod Christiansen.
