the and , until the truck crisis was resolved and the R10s were once again, for the most part back, on the and with only occasional usage on the until April 1983. In 1975, car 3192 had a new R42 type front installed; it was a prototype car for a complete rebuilding of the fleet, which would add modern interiors and air-conditioning. The unit was scrapped in 1980 inside Coney Island Yard and the rebuilding program never took place with the other cars because of the higher cost of rebuilding the cars as opposed to purchasing new cars. There was a light overhaul program for 110 of the WH-powered cars between December 1984 and February 1986 in an effort to get the entire fleet in a non-graffiti state. The rehabilitation of the select R10s was done in-house at a budgeted cost of $65,000 per car. Retirement Approximately 53 R10s were replaced by the R46s in 1977–8. While the remaining cars may have been considered the second worst operating revenue service car during the 1980s based on MDBF (Mean Distance Between Failures), doing better than only the R46s, many R10s outlasted the newer R11s and R16s. The remaining R10s were replaced by the R68s and R68As. The last train of GE-powered R10s and non-overhauled WH-powered R10s ran on November 10, 1988, ten days short of the 40th anniversary of their debut. This was an official date; some were still operating in service as late as February 1989. The rebuilt WH-powered R10s were withdrawn from March 1989 to September 8, 1989, when the last revenue service train ran on the . On October 29, 1989, a train of R10s (3018-3203-3182-2974-3143-3045-3145-3216) led one final farewell excursion run on various IND-BMT Division routes, including the then-new IND 63rd Street Line. After retirement, most cars were sent to what is now Sims Metal Management's Newark facility to be scrapped and processed. Most R10s were scrapped by June 1990; the last R10 to be taken off property was 3081, the last GE-powered car in existence. It was scrapped sometime in 1993. Two cars have been preserved: Car 3184 has been preserved by the Railway Preservation Corp. and was previously displayed at the New York Transit Museum. It was repainted into its original two-tone gray and orange striped paint scheme, similar to R7A 1575. The car was restored to operating status in 2017 and has been operating
