The u-bahn / subway cars are linked in a way that you can see all the way from one end to the other. I finally had an opportunity to photograph it empty . . . I only wish I had been prepared enough to run to one end of the train in time instead of being in the middle.
Great shot, it's a rare moment to find these empty. We don't have that kind of connected cars around here, but I can't remember a time when I have seen one car empty.:)
