context_page_description: Metro-North Railroad's New Haven Line runs from New Haven, Connecticut, southwest to Mount Vernon, New York. There it joins the Harlem Line, where trains continue south to Grand Central Terminal in Manhattan. The New Haven Line carries 125,000 passengers every weekday and 39 million passengers a year. The busiest station is Stamford, with 8.4 million passengers, or 21% of the line's ridership.
  This line was originally part of the New York, New Haven and Hartford Railroad, forming the southern leg of the New Haven's main line. It is colored red on Metro-North system maps and timetables; the New Haven used red in its paint scheme for much of the last decade of its history. The section from Grand Central to the New York-Connecticut border is owned by Metro-North, and the section from the state line to New Haven is owned by the Connecticut Department of Transportation. From west to east in Connecticut, three branches split off: the New Canaan Branch, Danbury Branch, and Waterbury Branch, all owned by ConnDOT.
  The New Haven Line is part of the Northeast Corridor; its share of the Northeast Corridor is the busiest rail line in the United States.
context_section_description: As with the Harlem and Hudson Lines, diesel-powered trains are driven by Brookville BL20-GH and dual-mode GE Genesis P32AC-DM locomotives, paired with Shoreliner coaches. While some peak-period trains operate directly to and from Grand Central Terminal with Genesis P32AC-DM dual-mode locomotives only, most New Haven Line diesel-only territory is operated as shuttle service between Danbury and South Norwalk, or between Waterbury and Bridgeport.
