The R46 is a New York City Subway car model that was built from 1975 to 1978 by the Pullman Standard Company in Chicago, Illinois for the IND/BMT B Division. They replaced all remaining Arnine cars, some R10s, and all GE R16s, which had many reliability issues. Along with the previous R44s, the R46s are 75 feet (22.86 m) long.
The R46s are numbered 5482-6207 and 6208-6258 (even numbers only). 5482-6207 were originally numbered 500-1227 (except numbers 941 & 1054, as those two cars were scrapped prior to overhaul), and 6208-6258 were originally numbered 1228-1278, even numbers only.
The R46 order consisted of 754 single cars, originally planned to be 745, that were numbered from 500 to 1278. Even cars with cabs are A cars; odd cars without cabs are B cars. The cars cost about $285,000 each. The first two trains of R46s were placed in service on the F and N on July 14, 1975, with a brief ceremony at 34th Street–Herald Square, attended by Mayor Abraham Beame and MTA Chairman David Yunich. The fleet is infamous for having had frequent problems in the first decade of service, but an overhaul from 1989 to 1992 provided solutions to the fleet's many problems. During the 1976 U.S. Bicentennial celebration, cars 680 and 681 had white, red and blue star bands on their bases and were respectively renumbered 1776 and 1976. The first R46s were assigned to the F train.
