Two independent teams will be working at the site.
The first team includes the two men who originally put forward a claim that they have found the train, Pole Piotr Koper and German Andreas Richter.
In August the claimants said they had found a 98-meter long “armored train” with gun platforms and a cargo of “precious metals” 70 years after it pulled out of Wroclaw (formerly the German city of Breslau) supposedly carrying a trove of gold and other valuable treasures back to Germany ahead of the Red Army's advance.
Instead of arriving at its planned destination of Swiebodzice, it is alleged that the train was lost without trace in the mountains around the town of Walbrzych. The two men say they have detected it eight to nine meters underground in a railway tunnel. They want ten percent of their supposed find.
The second team is comprised of specialists from the University of Science and Technology in Krakow.
Municipal spokesman Arkadiusz Grudzien said that the experts will be able to use different measuring equipment and detectors but are not allowed to dig or drill.
In October the Polish military forces, including a bomb squad, completed tests at the suspected site and declared it free of hazardous material.
Deputy Culture Minister Piotr Zuchowski said in August he was "more than 99 percent sure" the train exists after seeing ground-penetrating radar images provided by Piotr Koper and German Andreas Richter.
Claims that the train had been found this summer sparked a frenzy of interest, both within Poland and abroad, capturing the imagination of treasure-hunters.
The agiotage is fuelled by a massive network of secret underground tunnels near Walbrzych — including around formidable Ksiaz Castle — a fortress which Hitler had wanted to use as his base of operations in Eastern Europe.
According to Poland’s Radio Wroclaw, there are several theories about the train's fate. One story has it that the train entered a tunnel near Ksiaz Castle and never emerged. The tunnel was later sealed up and forgotten.
Historians, however, say that the Nazis dug miles of tunnels in the southwest mountains of what is now Poland in one of the biggest construction projects in the history of the Third Reich.
The reason for the tunnels remains a mystery, and some believers in the ghost train argue the Germans may have excavated secret railway stashes and hidden the loot in one of them for safe keeping.
The Nazis plundered loot from across Europe, and, as they faced defeat in 1945, anxiously hid it from the advancing Soviet forces.
Some were stashed away, while other pieces are believed to have been smuggled out of Berlin by high-ranking members of the Reich to fund their own escapes and allow them to establish new lives.
