This is the Circle and Hammersmith line platform at Baker Street station. Because both Circle and Hammersmith line trains share this track, I got on the wrong one a couple times by accident because unless you're paying attention to the next train signs or read the front of the train as it roars in, it's not obvious if you are running through the right doors.
The passengers lining up, I mean queuing up as they call it, echo the big pillars, but the pillars aren't going anywhere!
Compositionally the photograph is a triangle, the eyeflow starts at the bottom, follows the people left into the train, then the train takes you back to the top right, and the pillars draw you back down again to the people.
