The R40 was a B Division New York City Subway car built between 1967 and 1968 by the St. Louis Car Company in St. Louis, Missouri. The R40 cars were unique for their 10-degree slanted end (designed by the firm Raymond Loewy and Associates), and were often referred to as the R40 Slant.

Description[edit]

The R40 fleet was numbered #4150–4349; cars #4250–4349 were numbered #4350–4449 until 1970, while cars #4150–4249 retained their original numbers. This coincided with fleet renumbering of the R40A cars from #4250–4349/4450–4549 to #4350–4549.

The first incomplete pair of R40s (cars #4350-4351) 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.

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.[1]

Between 1987 and 1989, the R40s were rebuilt by Sumitomo in Elmira Heights, New York and retrofitted with air conditioning and a new interior design.[2]

Retirement, scrapping, preservation and usage[edit]

The R160 order has replaced all of the R40 fleet. The last slanted train—cars #4256–4257 in a mix with R40A slants—made its final trip on the A on June 12, 2009.[2]

Cars #4162-4163 were used as school cars at East New York Yard and were later transferred to Concourse Yard for storage. The pair was subsequently scrapped.

Cars #4192-4193 were on temporary display at the New York Transit Museum briefly in 2008 and were later reefed.[3][4]

Cars 4280-4281 (originally numbered 4380-4381) were designated to be preserved for the New York Transit Museum.[5][6] They were restored to operating status and are operated on certain excursions sponsored by the New York City Transit Museum.
