A substantial portion of the former New Haven main line between New York and Boston was transferred to Amtrak in 1976 and now forms a major portion of the electrified Northeast Corridor, hosting high-speed "Acela Express" and regional rail service. The main line between New Rochelle and New Haven is jointly owned by the state of Connecticut and the Metropolitan Transportation Authority of New York, and is served by the Metro-North Railroad’s New Haven Line and Shore Line East, providing commuter service from Manhattan’s Grand Central Terminal as far eastward as New London, Connecticut. After a lengthy hiatus, the line between New Haven, Hartford and Springfield is now operated by the state of Connecticut as the Hartford Line. The MBTA's Providence/Stoughton Line provides commuter service between Providence and South Station in Boston.
