London Underground S8 train Farringdon 25 2 2023

There must be scores of places where the tube pops up into the central London scene, most of which will be like this - grubby areas behind backs of buildings. Although I am very happy living on the south coast now, I do sort of miss the character of the grittier parts of London, having spent all my working life just south of the Thames.
I am not a fan of colour popping, although turning the background into a high contrast mono image might look good.
