These pictures reveal the crumbling ruins of the famed Grand Orient Express, now hollowed-out and almost reduced to rubble. There are only a couple of the trains, launched in 1883, left in the world. This example stands dormant in Belgium, untouched from its last voyage in the winter of 2009. Rusty ceilings, moth-eaten seats and tattered floors capture its level of decay.

Professional conceptual category winner. Greetings from Mars, by Julien Mauve, France. Mauve says: “I have always wondered what it would be like to discover a totally different world ... and to photograph it for the first time as if I was Ansel Adams.
