"Yes, there are more tourists here and it's difficult for the guides here because all the tourists keep asking about the gold train. It's tiring!"
Curious tourists are not the only ones excited by the Walbrzych mystery. The dark history of the area's Nazi occupation has inspired other treasure-hunters hoping to make similar discoveries of World War II artifacts.

Łukasz Kazek, a treasure-hunter from the nearby town of Walim, and Adam Hausman, that town's mayor, have used ground-penetrating radar to locate what they believe is a previously-undiscovered tunnel near an old rail station.
Even if investigators never find the gold train, Walbrzych may draw a long-lasting dividend from the search — a view held by the two original treasure-hunters, who hope to claim a 10 percent finders' reward in case their discovery is proven.
"We have already done a lot for Walbrzych," said Piotr Koper, from Poland. "It is a big advertisement for Walbrzych and the area."
His co-hunter Andres Richter, a German, said: "The train is still underground but city already has the gold!"
That view was echoed by the local historian, Mykytyszyn.

"Look at El Dorado. It is famous for gold never found, but has a lasting fame," he said. "Our beauty of mystery and history and or secrets of our past are now disclosed to the world and we are very happy. It's like a new era for Walbrzych and the area.
"Our town has 700 years of history and we were at a stop light until the train story. The interest in Walbrzych will stay now because there is so much to see here."
However, he added: "We must always remember the tunnels here were built on the blood and tears of the Holocaust victims and we should never forget that."
