CT Rail, stylized as CTrail, is the brand for commuter rail services overseen by the Connecticut Department of Transportation (CTDOT), in the U.S. state of Connecticut, with some service extending into Massachusetts. CTDOT oversees two lines: Shore Line East, between New Haven and New London, Connecticut, and the Hartford Line, from New Haven, through Hartford, to Springfield, Massachusetts.

New Haven State Street station is a commuter rail station located on State Street in downtown New Haven, Connecticut. The secondary railroad station in the city, it is located 0.8 miles (1.3 km) northeast of the much larger New Haven Union Station and is intended to offer easier access to New Haven's downtown business district. It is served by Shore Line East and Hartford Line commuter trains, Amtrak Hartford Line trains, Springfield-terminating Northeast Regional trains, and Valley Flyer trains, and a limited number of Metro-North Railroad New Haven Line trains. Originally proposed in 1996, State Street opened on June 7, 2002. A second platform opened on June 8, 2018, in time for the beginning of Hartford Line service.
