In Metro Vancouver you can’t leave the Skytrain stations if you are still inside the terminal when your ticket time runs out after you’ve arrived at your destination you need a new ticket to go in and out through the gates - unless you buy another ticket or have a debit-like prepaid card that works like a fob, with money left on it. If you don’t have that and no money for a new ticket, you’re stuck - you can’t even leave. Another thing that disproportionately affects poor people. They need to change that. Instead they’re beefing up measures to have more transit security monitor people sneaking through - like letting someone else open the gate and going in behind them might get somebody arrested who is just trying to get out. The fob like tickets/ cards only let you swipe once, one way - so one time I swiped on the wrong side - from the gate beside me (I was new at it) so the gate next to me opened. There’s only one wide gate I can go through - I paid I wasn’t skipping fare - so a man helped me out and swiped his ticket and I followed him through. To do that nowdays might create a humiliating and potentially dangerous situation. And so could trapping someone in who is volatile.
