The Jersey Arrow is a type of electric multiple unit (EMU) railcar developed for the Pennsylvania Railroad, and used through successive commuter operators in New Jersey, through to New Jersey Transit. Three models were built but only the third is in use today. The series is similar to SEPTA's Silverliner series, but include center doors among other differences in details. ==Arrow I== The first series of Arrows (classed MA-1A) were built in 1968-69 by the St. Louis Car Company; 35 were built and purchased by the New Jersey Department of Transportation. These cars were initially numbered 100-134. These cars were built with higher capacity 3-2 seating which caused grumbling by the passengers at that time. These cars bear some resemblance to the Silverliner III also produced by St. Louis Car company at the time, including a unique numberboard area. However, these cars are very different mechanically. They featured diamond-shaped twin-arm Stemmann pantographs, round windows, center doors, and a different body shape. Car 107 caught fire early in its career and was scrapped. Car 105 was also severely damaged in a collision in the East River Tunnel near New York Penn Station in 1975. It was stored in Sunnyside Yard until the mid 80s, when it was scrapped. During 1976, 19 of the 33 surviving Arrow Is were rebuilt to be compatible with the newly arrived Arrow IIs. This involved the replacement of Symington-Wayne SW800 "hook-type" couplers with the Wabco N2A couplers used by subsequent Arrow MUs. As they were rebuilt, they were renumbered 500-533, with car 134 being renumbered 507 to account for the loss of 107. A further renumbering of the Arrow Is to 1200-1233 was planned, however this was never implemented as the Arrow Is were instead retired. The Arrow Is were phased out and stored as additional Arrow IIIs arrived from General Electric. All cars were stored out of service by 1980 due to reliability issues with their Westinghouse control equipment. These problems were a result of poor wiring and frequent electrical grounds. 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「Arrow (railcar)」の詳細全文を読む スポンサード リンク
