R143 (New York City Subway car)
The R143 is a standard gauge subway car design used on the B Division of the New York City Subway in the United States. The cars are primarily used on the L service. 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.[1]

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 as many as 112 more.[2] The new design was based on the A Division's R142A, which Kawasaki also built,[3] and incorporated many features from the R110B prototype. Delivery began in late 2001, and a 30-day test with one train of eight cars began on December 4, 2001.[4] According to Kawasaki, the test was "extremely successful".[3]
R143s began running on the BMT Canarsie Line (L) on February 12, 2002,[1][5] and all 212 cars were delivered to the subway by March 2003.[6] In addition to the L,[7] where the R143s displaced the older R40 and most of R42 cars [1], they also displaced the R42s[8] on the M weekend shuttle service on the BMT Myrtle Avenue Line. The R143s on that line were replaced by R160A-1ss in February 2008. One-Person Train Operation was tested on the L during mid-2005.[9][10].
The 212 cars delivered were expected to provide enough service for years, but the fast growth of Williamsburg, Brooklyn overloaded the L by mid-2006.[11]
On June 21, 2006, an eight-car R143 train overshot the bumper at the end of the tracks in the Canarsie Railyard after the operator suffered a seizure. Lead car #8277 suffered frame damage and is being stripped of parts for possible repair, but may be permanently out of service.
