This forensic description details a static, eye-level photographic scene at a railway crossing within the city of Roubaix, France, under an overcast sky. The central subject is a heavily weathered utility structure comprising a rust-stained metal box affixed to an orange-painted wooden post. The uppermost section of the metal box features a rusty, open-mesh cage containing a white cylindrical object partially marked with a blue 'X'. Below this, a silver-colored metal panel exhibits numerous graffiti tags, including "POTOM," surface scratches, and residue from removed stickers. A prominent blue rectangular sticker bearing the white text "CARCETTI" is adhered to this panel. Below the metal box, a white rectangular sign with a blue border is mounted to the orange post, displaying "S.O.S." in black capital letters underneath a large, abstract black spray-painted obscuration. The orange wooden post itself is marked with light blue graffiti, spelling "NOH." To the immediate left in the foreground, a dark metal pole is partially visible, rooted in overgrown green grass and weeds that also surround the base of the orange post. A paved pedestrian pathway runs parallel to the road and railway line in the middle ground. In the background, a railway crossing barrier arm, painted with alternating red and white stripes, is in a raised position, indicating an open passage. To the left of the crossing, a road extends into the distance, bordered by trees exhibiting autumn foliage and several parked vehicles. To the right, the scene includes visible railway tracks, more overgrown vegetation, an industrial fence, and distant urban buildings under a uniform grey sky. No individuals, actions, or direct interactions are depicted.
