I was a bit shocked by New York’s subway; you always seems to have to wait a loooong time for a train. On the London Underground the carriages are much smaller but waiting even 5 mins for a train is vanishingly rare. Tokyo has a crazy subway that guarantees to almost the second when the trains go. You can literally say exactly when you’ll be somewhere across town down to the minute and it’s nearly never wrong.
