That Wi-Fi is unusable. Not only does the association & DHCP negotiation take a large part of the time the train spends stopped at the station, but there's a stupid captive portal that also wastes whatever valuable time & bandwidth you manage to get despite the other issues.

I've been travelling to places where conventional mobile service is available in the subway and it's such an improvement. Being able to look at maps, message or browse the net is a godsend especially as a tourist in a foreign country.
