After completing the test, representatives of the armed forces did not comment much on its results, saying only that they handed over a "safe parcel of land" to the local authorities.
"The army's job is done as we're not in the business of treasure hunting," Poland's Defense Minister Tomasz Siemoniak said, cited by the Polish PAP news agency.
It still remains unclear whether some evidence of the train’s existence has been found during the operation. Polish official Arkadiusz Grudzien stated only that the local authorities have not yet decided on their further steps.
The agiotage about the mysterious train started with renewed force in the middle of September after it was confirmed that a tunnel has been detected near the suspected site.
Last month, Polish citizen Piotr Koperand and German national Andreas Richter informed the public that they had detected a 98-metre-long train carriage buried eight to nine meters underground.
