yeah but that's london, almost half of people on each line have to transfer for their commute, and it seems like they're shifting everyone over to St. George, which is a lot worse from a crowding standpoint.Not really. This is a common practice on the tube. When I was in London in 2017 Oxford Circus was regularly shut down during rush hour and made exit only. This allow people to exit the station but not board.
You could not transfer between lines at the station during the shut down but it cleared out the crowds.
