A descent into the tunnel required hardhats and the giving up of all personal possessions, particularly cameras & phones (I really need to acquire a spy-camera). The tunnel is narrow and somewhat claustrophobic as the monorail took us down. At the end we could see where the tunnel had been blocked, and then we quickly headed back up.
The last stop on our tour was Dorasan Station, a railroad line that was intended to connect North and South Korea. Constructed in 2000, the hoped for connection didn't happen, and today the station lies vacant.

Maybe one day we will be able to take this train to Pyeongyang.
But for now we say goodbye. One more night back in Seoul and then home to Michigan.
