The R9 was a New York City Subway car model, which was built by the American Car and Foundry Company and the Pressed Steel Car Company in 1940 for the Independent Subway System (IND) and its successors, which included the New York City Board of Transportation and the New York City Transit Authority. Identical to the preceding R7/As, the R9s had distinctive curved ends on the rollsign boxes and contained distinct 2CY air compressors not featured on the older cars in the R1–9 fleet.[1] A total of 153 cars were built, numbered 1650–1802, and arranged as single units. They were the last R1–9 type cars that were ordered before the merger of the IND with the IRT and BMT in 1940.
The R9s were ordered in preparation for the opening of the IND Sixth Avenue Line, the second IND trunk line in Manhattan to open after the IND Eighth Avenue Line. They were used primarily for increased service in Queens and the opening of the Crosstown Line. They served exclusively on all IND lines for most of their service lives, but were also used on the BMT Division during their final years. The R46s replaced the R9 cars, with the final run taking place on March 31, 1977. Three cars were preserved, while the rest were scrapped.
