The R1 was the first New York City Subway car type built for the Independent Subway System (IND). 300 cars were manufactured between 1930 and 1931 by the American Car and Foundry Company, numbered 100 through 399, all arranged as single units. Nicknamed City Cars, the R1s were the first of five subway car classes collectively referred to as the R1–9 fleet, with future passenger stock orders – including contracts R4, R6, R7/A, and R9 – being virtually identical, with minor mechanical and cosmetic variations.
The first R1s were delivered in 1931, in anticipation for the opening of the IND Eighth Avenue Line. For their time, the R1s introduced several improvements to subway car design that greatly sped up the flow of passengers in and out of trains. The R40s, R42s, R44s, and R46s gradually replaced the fleet of R1s, with the final run taking place in 1976. Several R1 cars were saved for preservation, while the rest were scrapped.
