The R143 is a standard gauge New York City Subway B Division new technology (NTT) car built by Kawasaki in 2001-2003. The cars are mainly used on the BMT Canarsie Line ( train), but have been used on other BMT Eastern Division routes as well over their history. The New York City Transit Authority owns 212 R143 cars, numbered 8101 to 8312, and built for an average cost of about $1.5 million per car. ==History== Kawasaki Rail Car, Inc. was awarded a $190 million contract for 100 new B Division cars in late December 1998, with an option for 112 more cars.〔(Subway Job to Kawasaki )〕 The new design was based on the A Division's R142A, which Kawasaki also built,〔 and incorporated many features from the R110A and R110B prototypes. Delivery began in late 2001, and a 30-day test with one train of eight cars (8101-8108) began on December 4, 2001.〔(【引用サイトリンク】title=www.nycsubway.org )〕 According to Kawasaki, the test was "extremely successful".〔Kawasaki Rail Car, Inc., (New York City Transit R143 Subway Cars ), accessed April 14, 2007〕 R143s began running on the BMT Canarsie Line () on February 12, 2002,〔Randy Kennedy, New York Times, 1,700 Subway Cars to Be Built Under Largest Such Contract in New York History, July 31, 2002, page B3〕 and all 212 cars were delivered to the subway by March 2003.〔Railway Age, Kawasaki completes NYCT R143 order, March 1, 2003〕 In addition to running on the L,〔Patrick McGeehan, New York Times, Port Authority to Replace PATH Fleet for $499 Million, April 1, 2005, page B5〕 where the R143s displaced the R40/R40As and most of the R42s,〔(【引用サイトリンク】title=Showing Image 5251 )〕 they also displaced the R42s on the weekend shuttle service on the BMT Myrtle Avenue Line. The R143s on the M were replaced by R160As in February 2008. One Person Train Operation was tested on the L during mid-2005.〔(On L Train, Drivers Perform Solo, Without Conductors, June 20, 2005, page B3 )〕〔(Conductors Are Returning to the Subway's L Line )〕 Eight R143s numbered 8205-8212 were originally delivered with experimental Siemens traction motors to test the traction motors that would be later found in some of the R160B cars (numbers 8843-9102). These cars were eventually refitted with the Bombardier traction motors found on all other R143s. The 212 cars delivered were expected to provide enough service for years, but the fast growth of the Williamsburg neighborhood overloaded the L by mid-2006.〔New York Daily News, (Oh, L, not enuf trains! ), July 7, 2006〕 On June 21, 2006, an eight-car R143 train overshot the bumper at the end of the tracks in the Canarsie Yard after the operator suffered a seizure. Lead car 8277 suffered significant damage and has been stripped of damaged parts for repair.〔()〕 It was sent to the Kawasaki plant in Yonkers while the rest of the set (8278-8280) is at the 207th Street Yard.〔()〕 However, 8277 has been worked on for the past 5 years at the 207th Street and Coney Island Repair Shops and the repair work continues to be done.〔()〕 8278 also suffered a bit of body damage but was repaired sometime between 2009-2011 and coupled back up with 8279-8280. 〔()〕 〔()〕 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「R143 (New York City Subway car)」の詳細全文を読む スポンサード リンク
