The R68 is a B Division New York City Subway car order consisting of 425 cars built by the Westinghouse Amrail Company, a joint venture of Westinghouse, ANF Industrie, Jeumont Schneider, and Alstom. The cars were built in France from 1986 to 1988 and shipped through New York Harbor. They replaced many R10s dating from 1948, all remaining 6300-series R16s dating from 1954 to 1955, and some R27s and R30s dating from 1960 to 1962. ==Overview== The R68 was the third R-type contract to be built with cars (the previous two being the R44 and R46), which have more room for sitting and standing passengers per car than the cars that were used previously and afterward. The R68s manufactures suffered from significant system integration problems. Inadequate communication and coordination between the carbody builder (ANF Industrie) and the chassis assembler (Westinghouse) led to operational failures and the R68s became known as a lemon. However, extensive work performed by the New York City Transit Authority provided solutions to the fleet's many problems. The R68s first entry to revenue service was on June 20, 1986 on the Brooklyn half of the divided with the first fleet consisting of cars 2500-2507. There were two contracts to supply the R68 fleet. The primary order consisted of cars 2500-2724 while the R68-1 option order consisted of cars 2725-2924. R68s are based out of the Concourse Yard in the Bronx and the Coney Island Complex in Brooklyn and assigned to the , D, , and Franklin Avenue Shuttle. The R68s that operate on the Franklin Avenue Shuttle have some noticeable differences from the main line cars. These cars have permanent side signs instead of rollsigns, remain set up as single units with OPTO switches added (unlike the rest of the R68s, which have been configured into sets of four), and car 2923 has three-piece side windows. The R68s are scheduled to remain in service until at least 2025〔(MTA Capital Program Oversight Committee Hearing, June 2010 (page 20) )〕 and the MTA is proposing mid-life technological upgrades for the fleet including LED destination signs and automated announcements. However, it is unlikely that these improvements will be implemented in the near future.〔(Request For Information No. 9003 Integrated Communications System on NYCT R62/R62A and R68/R68A Class Rail Cars )〕 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「R68 (New York City Subway car)」の詳細全文を読む スポンサード リンク
