Two men in Poland claim they have found a Nazi train loaded with gold, gems and valuable art that according to local lore disappeared at the end of World War II as the Germans fled the advancing Soviet forces.

Marika Tokarska, an official in Walbrzych, where the train allegedly was found, says authorities received letters from a law firm representing the men, a Pole and a German who are remaining anonymous, saying they are seeking a 10 percent reward for revealing its location.

Tokarska told The Associated Press on Thursday that authorities are taking the claim seriously and have convened a meeting of firefighters, police and other authorities to explore how they can safely handle the train if it is located. She said it could be secured by explosives.
