An underground tunnel, which is part of the Nazi Germany "Riese" construction project, is pictured under the Ksiaz castle in an area where a Nazi train is believed to be, in Walbrzych, southwestern Poland September 3, 2015. Poland said on Friday it was almost certain it had located the Nazi train rumored to have gone missing near the close of World War Two loaded with guns and jewels. Photographs taken using ground-penetrating radar equipment showed a train more than 100 metres (330 feet) long, the first official confirmation of its existence, Deputy Culture Minister Piotr Zuchowski said.
