1954, when that line became part of the IND Culver Line. Upon delivery of the R16 cars in 1954–1955, the cars were returned to the IND Division. Retirement Most R1s were retired from 1968 to 1970 as age decayed the cars' internal components, causing the cars to perform worse than their newer contemporaries. Some were replaced by the R40s while many more were replaced by the R42s, but some remained past 1970 until being retired and replaced by the R44s. However, car 369, which was renumbered to 576 on October 3, 1969 and then to 1768 on August 27, 1973, was transferred to the East New York Yard. It ran on the Eastern Division until December 1, 1976, when it was finally replaced by the R46s. Following their removal from service, the majority of the fleet was scrapped. A small number of cars remained in work service and were used until the 1980s. Several other cars have been preserved and remain today, including: 100 – preserved by the New York Transit Museum and restored. It is the first car of the Arnine fleet, numerically. 103 – preserved by Railway Preservation Corp. and restored. This car was retrofitted with axiflow-type fans in the 1940s. 381 – preserved by Railway Preservation Corp. and restored. Car 175 is at the Seashore Trolley Museum, but is used only for storage and as a source of spare parts. It does not have trucks, and two of its side doors were donated to R4 401, which has been preserved by Railway Preservation Corp. and restored.
