When Piotr Koper and Andreas Richter announced in late August that they had found a train hidden by the Nazis at the end of the Second World War, the news made headlines around the world.
The hunt for the train has now started, with Koper and Richter undertaking the search along with experts from the Polish Mining Academy.
The team will deploy hightech equipment including thermo-cameras, geo-radar and magnometers to locate the elusive loot.
In October the Polish military moved in to secure the area near Breslau, scouring the scrub land for mines and uprooting dense thickets.
"The area is more easily accessible now,“ said Koper, speculating that the first results would not take long to gather. "We could publish our findings at the end of November."
The treasure hunters have so far remained tight-lipped about the details of how and where they found the train, but insist they have a right to a finders' fee of ten percent of its value.

For decades, rumours have circulated in the area that the Nazis hid the train in a network of underground tunnels they had built in Lower Silesia.
"When I first came to this region 13 years ago I didn't take the stories seriously – they were just fairy tales to me,“ Koper said.
But when he started to look into the story he became convinced it was true.
"These are no myths. That train exists,“ he assured.
"At least three different secret services have hunted for this Nazi treasure,“ he said, claiming that he was able to locate it because sophisticated technologies are now also available to hobby researchers.
"Sometimes one needs a bit of luck, and that was the case with us. We came across a witness who told us where to search, and suddenly all the pieces of the puzzle came together.“
But even he was surprised with the results of his search, he claims.
"We were actually just looking for a tunnel and then we came across the train.“
