1844 Brooklyn - Boston Line
Welcome to 1844 Brooklyn - Boston Line, a unique local business located in the historic Greenport, New York, 11944. Our name pays homage to a significant chapter in American rail history—the establishment of the Long Island Rail Road (LIRR) and its ambitious plan to connect New York to Boston via Greenport. This visionary route, conceived in the early 19th century, was designed to outpace the traditional path through southern Connecticut by avoiding major water crossings, thus offering a more efficient journey. The LIRR, one of the oldest railroads in the United States, began its journey as the Brooklyn and Jamaica Rail Road in 1832, with the goal of creating a rail line that spanned the entire length of Long Island. By 1834, it was officially chartered, and by 1844, the tracks reached Greenport, establishing a vital link that reduced travel time between New York and Boston from nearly fifteen hours to eleven. This achievement marked a significant milestone in American transportation history.
