Same here in NYC. Before Covid, the trains and buses that I rode were packed. For 2 years they were empty; I always had plenty of seats, even during the proverbial rush hour.
Now they're filling up again -- however, mostly with immigrants or SJW types. Or bums sleeping on the seats or mumbling to themselves (or stinking up the cars!).
Few professionals, even blue-collar, or Wall Street types. Everyone looks like they're dressed for the beach or laundry room. Many of the wealthy whites fled permanently; they are presumably working remotely or driving in.
The trains have gotten so depressing. I feel like I'm traveling in a 3rd World country.
The route I live on is Monday to Friday route. There is an another bus route a few blocks away that operates on the weekends. From what I can tell, they could close down the route next to me or reduce the bus size to something like a bus operating from a seasoned citizens home. Deviant behavior isn't really an issue here. That said, there is no way in hell I would catch the Amtrak to Chicago and then take the blue line to O'hare for a flight...
