The R4 was a subway car purchased for the IND division of the New York City Subway. They were built by American Car and Foundry Company between 1932 and 1933, and were practically identical to the original R1 order. The R4s had a slightly different side door panel than the R1, adding small handle notches below the door window. The 500 R4s were numbered 400-899 to continue the R1's sequence of numbers. The R5 contract order was for trucks and motors for R4 fleet. In 1932, each new car cost $30,633 for the carbody under contract R4.
The contract of subway cars was ordered to equip extensions of the IND in Queens, the Bronx, and Brooklyn.
The R4's were used for service on the IND exclusively until 1972-73, when many were retired, and replaced by the R44's. Some still usable R4's were salvaged and renumbered with number plates removed from out of service newer R6 thru R9 series cars, and were transferred to East New York Yard of the Eastern Division, and were used on the former BMT J, KK, LL, M, and QJ routes until 1977 when these renumbered R4's were finally retired and replaced by the R46's.
