This is a wonderful rundown.

MNRR is nearly always on time, and the electrics they run are the most reliable trains in the country. The trips are padded, so you may get into Harlem or GCT early, and always early into New Haven. It's only 4-5 mins from West Haven.

But it's way too expensive. Interstate CT fares are okay. Try transit or biking to the station to save on a permit & stress. Have a good lock, though, on both frame and at least front wheel. There are covered spots outside next to the garage.
