WARSAW: The mystery surrounding a fabled Nazi gold train allegedly buried in southwestern Poland intensified Friday after a week of tests by an army unit including a bomb squad appeared to have produced no clues.

The army was tight-lipped, saying only that after completing the tests it had handed over a “safe parcel of land” to Walbrzych municipal authorities. “The army’s job is done as we’re not in the business of treasure hunting,” Poland’s Defense Minister Tomasz Siemoniak said, quoted by the Polish PAP news agency.

Both military and municipal authorities refused to divulge whether they had found any hard evidence suggesting the train is more than just a treasure hunter’s fantasy.

“We haven’t yet decided what to do next,” Walbrzych municipal spokesman Arkadiusz Grudzien told AFP.

City hall would consult the interior ministry about its future steps, he added. Siemoniak said he expected Walbrzych mayor Roman Szelemej to contact Culture Minister Malgorata Omilanowska to plan his next move.

“It’s also a matter of finding funding as it’s quite a costly business if you excavate,” Siemoniak said.

Last month, two men claimed to have used ground-penetrating radar to discover an armored Nazi train buried at the end of World War II. Suggestions that it could be stuffed with jewels and gold stolen by the Nazis have made headlines around the globe.
