The Amtrak journey from Boston South Station to New York Penn Station (specifically the Moynihan Train Hall) on the Northeast Regional or Acela routes typically includes several key stops across Massachusetts, Rhode Island, and Connecticut. Major stops usually include Back Bay (Boston), Route 128 (Westwood, MA), Providence (RI), Kingston (RI), Westerly (RI), Mystic (CT), New London (CT), Old Saybrook (CT), New Haven (CT), Bridgeport (CT), and Stamford (CT), before arriving at New Rochelle (NY) and finally New York. The high-speed Acela service is more selective, often skipping smaller stations like Mystic or Old Saybrook to achieve its faster travel time of roughly 3.5 hours. For travelers in 2026, the Northeast Corridor remains the busiest passenger rail line in the U.S., offering frequent departures. Many trains also continue south from New York to Philadelphia and Washington, D.C., making it the primary artery for transit along the Eastern Seaboard.
