on the metropolitan line during rush hour it’s not too bad, people do keep a distance and wear masks
I got on the picadilly line yesterday (saturday) there were so many people most but not all were wearing masks
I got on the overground a few times, no one keeps a distance, people are sitting next to each other but most have masks
The jubilee line is the same as the metropolitan id say but tbh i havent got on that during rush hour yet
