The R40 fleet was numbered 4150–4349; cars 4250–4349 were originally numbered as 4350–4449 until 1970 (cars 4150–4249 retained their original numbers). These cars were unique for their 10° slanted end, designed by the firm of Raymond Loewy and Associates.
The first incomplete pair of R40s (cars 4350 and 4351) came onto TA property in November 1967 for promoting the Transportation Bond issue on Election Day. On March 23, 1968, the R40 fleet entered service on the F train.
The New York City Transit Authority found great dangers along with other hazards with the slanted end design posed with the lack of handholds for riders walking between cars, thus the danger of the passenger falling onto the tracks, and other design flaws. Within months, the cars were retrofitted with large grab rails with pantograph gates mounted, which effectively destroyed Loewy's design, but allowed passengers to travel safely between cars.
Retirement, scrapping and preservation
Cars 4192-4193 were on temporary display at the New York Transit Museum briefly in 2008 and were later reefed.
