It's funny, we are almost certain that it exists and the only problem is location. But before even getting into it we already have claims from Jewish organizations(World Jewish Congress), soon there will be from Russia and possibly others. Nobody tires to remember that according to the story, the train was mined, so firstly someone would have to safely disarm all explosives.
I just hope in all that silly excitement that nobody will get hurt, that would be crap if 70 years after the war someone would die in such operation. And it wont end the way that we will do the dirty job and others will enjoy fruits of it.
