North Korea's North Korean media agency, 38 North, said that the train, believed to be Kim Jong-un's private train, has stopped at a train station in Wonsan, North Korea since at least 21 days ago.

In the midst of mixed reports surrounding Kim's health ideals, Kim is further empowering what is known to be staying in Wonsan after the presidency of the Political Bureau.

Based on commercial satellite photographs, 38 North reported that the train is stopping at a station near Kim's Wonsan recreational facility.

"The existence of trains does not prove the North Korean leader's whereabouts or suggest anything about health," said 38 North.
