The R142 is the first model class of the newest generation or new technology IRT cars for the New York City Subway. Built by Bombardier in La Pocatiere, Quebec and Barre, Vermont with final assembly performed at Plattsburgh, New York, from 1999 to 2003.〔("Some New Subway Cars Put Into Service Monday" ) NY1 - 10 July 2000. Retrieved on 24 April 2008〕 ==Background== The 1,030 R142 cars have Alstom ONIX AC propulsion, electronic braking, automatic climate control, and an on-board intercom system. The R142 and the R142A was partly designed by Antenna Design.〔(【引用サイトリンク】title=Antenna: News )〕 The first 10 R142s numbered 6301–6310 were delivered on November 16, 1999. Regular service began on the train on July 10, 2000, after several months of testing and troubleshooting of all bugs. The R142s and R142As replaced all of the Redbirds—the R26, R28, R29, R33, R33 WF, R36 and R36 WF IRT cars by late 2003. There are two types of cars: "A" (cab at one end) and "B" (no cabs). "A" cars are powered with four traction motors each, with the passenger doors opposite each other. The "B" cars are powered by two traction motors at the number-two end, and the passenger doors are staggered (car ends are numbered on the lower body just above the truck).〔(【引用サイトリンク】title=Showing Image 3427 )〕〔(【引用サイトリンク】title=Showing Image 100281 )〕 The trains are linked up in A-B-B-B-A sets, but also can be linked in sets of 4, 6, 9, or 11 cars. The R142/A cars are similar to the R110A cars, with 54-inch side doors (about 9 inches narrower than the R110A doors, which were 63 inches, and 4 inches wider than the doors on the R62/As, which were 50 inches). All car ends have windows, allowing passengers to see through to the next car, except unit ends, where the cab walls prevent such visibility. R142 car bodies are stainless steel. 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「R142 (New York City Subway car)」の詳細全文を読む スポンサード リンク
