R4 is the contract number for the second order of standard subway cars 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.
