Two explorers using underground radar believe they've found a Nazi train trapped in a secret tunnel -- and possibly booby trapped.

Local legend suggests a Nazi train full of gold was sent to a network of underground tunnels Germany was making in Poland. As they began to lose the war and Soviet Russian troops advanced, the Nazis hid the train and its contents.

The underground radar suggests there is a train in a forgotten tunnel, but several experts doubt is has gold.

The explorers are asking for 10 percent of whatever is found, but they may not be legally entitled to it.

The Polish military was sent in to uncover the train because it likely has chemical weapons on it.
