Several railroads have been called the oldest in North America. == Early experimental railroads == *1720: A railroad is reportedly used in the construction of the French fortress at Louisburg, Nova Scotia. *1764: Between 1762 and 1764 a gravity railroad (mechanized tramway) (Montresor's Tramway) is built by British military engineers at the Niagara Portage in Lewiston, New York. It was designed by Captain John Montresor. It replaced manual labor performed by Seneca porters and was in use until the early 1800s〔http://historiclewiston.org/downloads/the_cradles_tramway_placemat.pdf〕 *1795: A wooden railway on Beacon Hill in Boston carries excavations down the hill to clear the land for the State House. *1799: Boston developers begin to reduce the height of Mount Vernon, prior to building streets and homes. Silas Whitney constructs a gravity railroad to move excavated material down the hill to fill marshy areas to create new land from the Back Bay. *1809: In September, an experimental railroad is built next to a Philadelphia tavern by a millwright named Somerville. The track, built for Thomas Leiper, has a grade of 1-1/2 inch to the yard (1 : 24 or about 4%) over its total length of and proves satisfactory when tested with a loaded car. * 1810: The Leiper Railroad, designed and built by merchant Thomas Leiper, connects Crum Creek to Ridley Creek, in Delaware County, Pennsylvania. It is used until 1829, when it is replaced by the Leiper Canal, then is reopened to replace the canal in 1852. This became the Crum Creek Branch of the Baltimore and Philadelphia Railroad (part of the Baltimore and Ohio Railroad) in 1887. This is the first railroad meant to be permanent, and the first to evolve into a common carrier after an intervening closure. See the 1826 Granite Railway (pictured) for comparison. *1811: George Magers designs and builds a wooden gravity railroad between a gunpowder mill and its powder storage bunker at Falling's Creek, Virginia. *1815: New Jersey grants a charter on February 6, 1815, for a company to "erect a rail-road from the river Delaware near Trenton, to the river Raritan, at or near New Brunswick", as proposed by John Stevens (1749-1838). This New Jersey Railroad Company is the first railroad chartered in the United States, but fails to attract investors and is never built. *1816: A railroad is reportedly used at Kiskiminetas Creek, Pennsylvania. *1818: An iron-smelting furnace at Bear Creek, Armstrong County, Pennsylvania, reportedly has a wooden railroad in operation.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oldest railroads in North America」の詳細全文を読む スポンサード リンク
