I commented on someone's photobucket account once that his ulta detailed videos of the NK metro should be national news, I wonder if he took my advice...
Creepy, especially the escalator. Its like its straight out of that movie Logans Run. The paintings on the walls are an interesting, soft touch. I guess their leader wasn't all bad as the west would have you believe.
The current cars as seen in your photos are BVG Type D and were built in West Berlin (before October 1990) using West German components.
