A train carting Nazi gold that has been missing for decades has been mysteriously uncovered.

The train in question was rumored to have gone missing toward the end of World War II. It was carrying away precious gems and weaponry as a means to keep the bounty out of the hands of the advancing Soviets.

Two unnamed individuals, one Polish and one German, reportedly found the enigmatic train. Lawyers representing the duo contacted authorities in Poland’s south-western district of Walbrzych. The pair was seeking to be paid 10 percent of the treasure’s net worth.

“Lawyers, the army, the police and the fire brigade are dealing with this,” Marika Tokarska, an official at the Walbrzych district council, told Reuters.

“The area has never been excavated before and we don’t know what we might find.”

The story of the train has become part of local folklore in the region, with rumors swirling that the train entered a tunnel near Ksiaz Castle in the mountainous Lower Silesian region in the year 1945, and was then never seen again. However, many people long believed that the train never existed at all.

Trains were commonly used by German forces to cart valuables in World War II in an aim to keep the wealth from foreign hands. A similar story of the “Gold Train,” which carted a comparable booty to that of the recently uncovered locomotive, dealt with a Budapest-bound train intercepted by US soldiers. That train’s cargo had an estimated worth of $200 million.
