Thank you for comment : )

That’s a good interpretation. You can also add the two women in black to the reading: they belong, or at least want to appear to belong, to a higher social group than the workers heading home.

They are visibly close to each other, and for them the evening is probably just beginning, while most of the others are on their way back home.

The woman in red, although physically close to the two women in black, is slightly apart. She doesn’t really belong to any of the social groups present in the station. Her attention is caught by the screens, all showing the same advertisement. She seems to be the only one who notices this detail, as if the ad was meant only for her.
