context_page_description: The Metro-North Railroad Harlem Line, originally chartered as the New York and Harlem Railroad, is an 82-mile commuter rail line running north from New York City into eastern Dutchess County. The lower 53 miles from Grand Central Terminal to Southeast, in Putnam County, is electrified with a third rail and has at least two tracks. The section north of Southeast, sometimes called the Wassaic Branch, is a non-electrified single-track line served by diesel locomotives. The diesel trains usually run as a shuttle on the northern end of the line, except for rush-hour express trains in the peak direction and one train in each direction on weekends.
  With 38 stations, the Harlem Line has the most of any Metro-North main line. Its northern terminal, Wassaic, is the northernmost station in the system. It is the only Metro-North line used exclusively by that carrier and the only one that uses the entirety of existing track. Metro-North has assigned it the color code blue, used as trim on station signs and spot color on printed timetables. The blue color-coding appears to have started with timetables issued by predecessor New York Central for the then-Harlem Division as far back as 1965.
context_section_description: The Harlem Line hews closely to roads along river-based transportation corridors dating back to even pre-rail times. It follows three major parkways closely from the Bronx northwards through Westchester: the Bronx River Parkway (and a short portion that becomes the Taconic State Parkway), the Saw Mill River Parkway and Interstate 684. In the last section it also begins to run close to NY 22, the long north-south two-lane state highway that parallels the eastern border of the state. In Westchester, it serves some of that county's most affluent communities as it slowly trends eastward.
