WARSAW, Poland — A spokesman for explorers searching for a legendary Nazi "gold train" in Poland says there is "no train, no tunnel" at the site where they have dug extensively.

Last week explorers moved in with heavy equipment and dug deep at a site in the southwestern town of Walbrzych, following comments by residents and tests using earth-penetrating radar. Local legend says the Nazis hid a train with valuables in a secret tunnel there in 1945.

But the explorers' spokesman, Andrzej Gaik, told The Associated Press on Wednesday that they found "no train, no tunnel" there. The machines are now covering over the pits that cost 140,000 zlotys ($37,000) to dig.

Gaik said "hope dies last" and a search using probes will resume at a nearby site in September.
