the T was lightyears ahead of the Dublin metro system.
Wow, Dublin's metro must suck. Boston's subway is good by US standards, but it's one of the worst of any major city I've been in elsewhere. The Green Line is more a tram than a subway line, and has that horrible tight turn under Park Street. For a city the size of Boston it has a decent number of different subway lines, but the whole system is old and poorly maintained.
