Two treasure hunters began detailed tests Tuesday in the hope of revealing a fuller picture of a Nazi train they claim is buried in a hillside.
Piotr Koper and Andres Richter reignited decades of speculation in August when they announced they had located the train close to the town of Walbrzych, Poland.
According to local folklore, a train loaded with gold, jewels and weapons was hidden in a sealed tunnel by Nazi forces retreating from the advance of the Soviet Red Army in 1945.

Koper, a Polish national, and Richter, a German, have already produced what they say is a rudimentary image of the train using ground-penetrating radar.
But now the trees above the site have been cleared, and the Polish military has checked the site for explosives, the treasure-hunting pair were set to carry out three days of more detailed scans.
