I don’t know if I will ever get used to how full trains get during rush hour. At one point this evening, with the press of people, I wasn’t able to keep both feet on the ground. I had to fight to stay standing as everyone around me was much bigger.
I’ve often wondered what would happen if the train stopped suddenly. Tonight at Shinjuku something got stuck in the door. The train started forwarded for a couple of seconds and then appeared to stop dead. Most people managed to stay standing with only one person in the carriage falling over. Thankfully it wasn’t me.
