[edit] 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.[1] The new design was based on the A Division's R142A, which Kawasaki also built,[2] 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.[3] According to Kawasaki, the test was "extremely successful".[2]
R143s began running on the BMT Canarsie Line (L) on February 12, 2002,[4] and all 212 cars were delivered to the subway by March 2003.[5] In addition to the L,[6] where the R143s displaced the older R40 and most of the R42 cars [7], 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 R160As 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 Yard after the operator suffered a seizure. Lead car #8277 suffered significant damage and has been stripped of damaged parts for repair. It is currently at the Kawasaki plant in Yonkers while the rest of the set (8278-8280) is at 207th Street Yard.
