The image is a warning sign on a wall in a train station. The sign is rectangular in shape and has a red background with white text. The text reads "DANGER" in French, which translates to "Danger" in English. Below the text, there is an illustration of a train with a red cross over it, indicating that the train is not allowed. 

On the left side of the sign, there are two figures, one of a man and the other of a woman, standing on the platform. The man is holding a sign that reads "FR: Avant de descendre du train, assurez-vous qu'il" which is French for "Do not enter the train". On the right side, it is a yellow arrow pointing to the right, which is likely indicating the direction of the train.

The sign also has a yellow border and a black background.
