Nice shot and a good crop with the arrow top right.
This view daytime would be a mess I suspect; with the catenary of the metro and possible other overhead cables 'blocking' the view.
The localised night lighting makes it work.
Looks like there's another view, with white car lights (instead of red), the other side of the station possibly
I like this a lot,
I like the fact that you obviously used a shutter speed of at least a few seconds and still were able to get the couple in focus.
Pure Luck. Exposure time was 20 sec at f/16, ISO 100. I did not imagine to see any person on the picture that sharp.
