Different cities. Different transport situations. I'm not convinced I would take commuter rail in and out of where I live to Boston even if it ran more frequently. Chicken and egg and all that but it's empty in the evening as it is.

Even the reverse commute in the evening is annoying but then it's quite straightforward to go home. There are usually reasonable parking options. Personally, not sure I'd use it outside of rush-hour in and back.
