The Daily Photo #98 by Tim Neumann of Softlite Studios.com
I think this is the Farragut North Metro Station, Washington DC, but honestly the exact station is a little elusive to me now.

This image is all about timing and framing. Timed the trains/platform so that I could get what would otherwise be a busy metro station stop at a quiet moment. This was taken during the morning, around 10:00 a.m., so waiting for that correct moment paid off. Framing the image, was simply a matter of making sure that I had the station center in the center of the frame and a focal length that included everything I wanted in the final image.
