A busy (!!) station on a Sunday afternoon in IR

My second attempt at IR black-and-white photography. This is actually a 210 seconds long exposure of a busy station (Nerima -- it was busy, although one cannot see it) in Tokyo, on a bright and sunny Sunday afternoon, on my way to a Meetup event (http://www.meetup.com/The-Nerima-West-area-in-Tokyo-Chat-Room-in-English/events/84765372/). I should really do some nature photography with the IR filter. This time, the white balance was set more correctly. Notice the ghosting of the trains on the platform. The human beings have become nearly transparent resulting in a deserted station, but in reality it was quite the opposite.
