I have become very familiar with this station, going to Paris very often. The Art Deco building was designed by Henri Pacon and inaugurated in 1932. It is always tempting to photograph a train station. But the activity is irregular. So at some point, the place is packed with busy crowd and it becomes difficult to get a general picture. You inevitably have somebody doing something so you have basically people pictures. But in between trains, the place can be rather empty, like it is in that shot. Then what matters is a balance of masses and colors that can become rather abstract.
