R68 (New York City Subway car)

R68 is a New York City Subway car. The 425-car contract was a joint venture of Westinghouse AM-Rail Company, ANF Industrie of Paris, and other companies. The cars were built in France from 1986 to 1988 and shipped to New York Harbor. File:Rockfeller Center Station By David Shakebone.jpg

The R68 was built by combining R46 and R62A features to build a better, state-of-the-art subway car with high Mean Distance Between Failure (MDBF), leading to better service. R68 was the third R-class contract to be built with 75-foot (23 m) cars, which have more room for sitting and standing passengers per car than the 60-foot cars that were used previously. However, because 75-foot cars take longer to load and unload, more recent orders have returned to 60-foot cars.

The R68's first entry to revenue service was on June 20,1986 on the D service; the first cars were numbered 2500-2507. There were two contracts to supply the R68. The primary order was: 2500-2727, and the R68-1 option order was 2728-2924. The fleet today primarily runs on the D, N, Q, S (Franklin Avenue Shuttle), and very rarely on the B and W. R68s are based out of the Concourse Yard in the Bronx and the Coney Island Complex in Brooklyn.

History

In 1985 the brand new R68 was being deliverd. In January 1986 it made an test run on the D train. On June 20,1986 the R68 ran full time on the D Line. In 1987 when the N and R switch Northern terminals the N and Q Trains recived the next batch of the R68. In 1996 the S shuttle recived some R68. In 1998 the R40 went to the Q Line while the R68 went to the B Line. In 2000 the B recived 20 more R68. On July 22 2001 the Q and the brand new W trans recived some R68 from the B and D Lines due to construction but the B and D still had entirely R68. On February 22 2004 the D had the highest R68. The B and W gave up its R68 to the N Line. Sometimes the B will borrow the R68 from the D or Q Lines and when there's an occur on the N line the R68 can be change to a W train.

Future Planned

When the R160 is deliverd 205 more R68 will be deliverd and it will run on the B, D, N, Q, S, W and very rarely on the A and C.
