The Delaware Extension was a rail line owned and operated by the Pennsylvania Railroad in the U.S. state of Pennsylvania. The line, located in the city of Philadelphia, Pennsylvania, ran from Arsenal Interlocking in West Philadelphia southeast, south, east and north to the intersection of Delaware Avenue (now Columbus Boulevard) and Dock Street. It junctioned the West Philadelphia Elevated Branch at Arsenal, crossed the Schuylkill River on the Arsenal Bridge, intersected with the Washington Avenue Branch, Girard Point Branch, Swanson Street Branch (twice), and Washington Avenue Branch again in South Philadelphia, and became the Delaware Avenue Branch at Dock Street.〔Pennsylvania Railroad, (Form CT1000, List of Stations and Sidings and Instructions for Making Reports to the Superintendent Car Service )〕 The line from Arsenal to Greenwich Yard on the Delaware River is now part of CSX Transportation's Harrisburg Subdivision. From Greenwich Yard north to Dock Street, the line is owned by the Philadelphia Belt Line Railroad and used by both CSX and the Norfolk Southern Railway under Conrail trackage rights.〔(Conrail System Map Showing The Proposed Allocation Of Conrail Lines & Rights ), July 9, 1997〕 ==History== Construction began on the first piece of the line, from Arsenal (then on the West Chester and Philadelphia Railroad) over the Arsenal Bridge to Washington Avenue west of 25th Street (then on the Philadelphia, Wilmington and Baltimore Railroad's main line), in 1860.〔, May 2004 Edition〕 The PRR acquired trackage rights over the WC&P from their main line at Market Street south to Arsenal in exchange for building a second track to handle the increased traffic.〔, May 2004 Edition〕 The PRR also gained trackage rights over the PW&B and their leased Southwark Rail-Road to the foot of Washington Avenue at the Delaware River, and the line opened on January 27, 1862; the PW&B was allowed to use the Arsenal Bridge as part of the agreement.〔, May 2004 Edition〕 The PRR began using the newly opened Junction Railroad rather than the WC&P on August 12, 1866.〔, June 2004 Edition〕 The first extension, south on 25th Street to Long Lane (Point Breeze Avenue) and then southwest to the Philadelphia Gas Works at Point Breeze, opened on January 27, 1863.〔, May 2004 Edition〕 It was extended further south along 25th Street and east along the current Schuylkill Expressway alignment to the Delaware River at Greenwich Point in March 1866, giving the PRR its own port.〔, June 2004 Edition〕 In July or August 1874, it was extended north along Delaware Avenue (Columbus Boulevard) to a new freight station at Dock Street, replacing the PRR's use of the City Railroad along Market Street.〔, March 2005 Edition〕 A new alignment for the east-west part was built later. The line passed to Penn Central Transportation in 1968, Conrail in 1976, and was assigned to CSX Transportation in 1999, becoming part of their Harrisburg Subdivision. 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「Delaware Extension」の詳細全文を読む スポンサード リンク
