The suburban rail in Boston is very much commuter rail. I live about 50 miles west (pretty near a station though I have to drive) and I'll absolutely take it for a 9-5ish urban event. But it's completely useless for anything in the evening.
Its good in NYC for american standards. For european standards the NYC subway is abominable. The smells, the grime, the homeless, its honestly like visiting the 6th ring of hell. Source: I am a european living in NYC.
