FILE - Then North Korean leader Kim Jong Il waves out of a window of his armored train at the Russian border railway station of Khasan, Russia, on Aug. 20, 2002. North Korea’s Kim Jong Un's train journey to Russia has a storified history. The tradition of train travel extends across the generations. That’s in evidence at the massive Kumsusan Palace of the Sun, where reconstructions of Kim Jong Un’s father’s and grandfather’s train cars, and the leaders’ preserved and displayed remains, are enshrined.
