The R28 was a New York City Subway car model built by American Car and Foundry (ACF) from 1960 to 1961. The cars were a "follow-up" or supplemental stock for the A Division's R26s and closely resemble them. The average car cost per R28 was $114,495. A total of 100 cars were built, arranged in married pairs.
The R28s entered service in late-1960 and received air conditioning by 1982. The fleet was rebuilt by Morrison–Knudsen between 1985 and 1987. The R28s were replaced in 2001 and 2002 with the delivery of the R142 and R142A cars with the last train running on October 7, 2002. After being retired, most R28s were sunk into the ocean as artificial reefs, but four cars have survived.
