Connecting Wall: 2023 edition

The 16 stations below need to be separated into 4 groups of 4 where each group has a specific theme. An example group would be Bank, Hackney Downs, Northwick Park, Wanstead Park; stations connected to other stations on the tube map. There are probably a number of different ways this could be done but there is one "neat" solution I am looking for. That's "neat" in the sense of not being able to swap any stations between groups without making one or more of the links less specific or outright changing the links. Of course, just as on Only Connect there will be red herrings to watch out for so try and identify what they are by considering which other groups they might fit into.

As for the rules on guessing I would kindly request that no-one submits any guesses until Boxing Day at the earliest. That way it gives everyone some time to think about it and also means I don't have to worry about this while I'm focussed on Christmas stuff. After that point feel free to make suggestions for possible groups of 4 and I will aim to respond when I'm available if you are right, wrong or semi-right. For Boxing Day specifically I'd appreciate one guess at a group per person at any one time just so I don't get flooded with too many guesses all at once to respond to. After that it'll probably be open season.
