R40 (New York City Subway car)
From Wikipedia, the free encyclopedia
The R40 (sometimes referred to as R40 Slant to distinguish it from the later R40M) is a New York City Subway IND–BMT car, built in 1967–69 by the St. Louis Car Company, St. Louis, Missouri. These cars were unique for their 10 degree slanted end, designed by Raymond Loewy of Studebaker fame. The slant design did not work in very well in service, resulting in numerous modifications to the R40 fleet early on in their service life. Some early plans for the R40 fleet involved 5 car sets with slants only on the ends.
The first R40 set was delivered in November, 1967. In April 1968 the first cars went into service on the F service (6 Avenue Local).
The New York City Transit Authority found great dangers with the slant, with the lack of handholds for riders walking between cars, the danger of the passenger falling onto the track and other flaws in the design. All R40 cars were later retrofitted with pantograph gates at the ends. With the poorly conceived slant design, NYCTA had the last 100 R40 cars (R40M) built with a non-slant end similar to the R42. 200 R40A's (100 R40A slants and 100 "R40M") were built with original air conditioning.
In 1987–1989 the R40's were rebuilt by Sumitomo in Elmira Heights, New York.
Currently, R40 cars can be found on the B line. They also make some appearances on the N and W and are used to provide extra service on the D and Q during construction, games at Yankee Stadium, or the holiday season. They are based at Coney Island Complex yard in Brooklyn and the Concourse Yard in the Bronx.
The R40 cars are numbered 4150-4349. The R40A cars (slant end) are numbered 4350-4449 (100 cars), and the R40M (modified non-slant) are numbered 4450-4549 (100 cars). In January 2008, the R40 pair 4192-4193 was sent to the New York Transit Museum. They will most likely be preserved and moved to a yard. [1]. The R160A/R160B order will replace some or all of the R40 fleet. Some R40s have been retired. R40 cars being prepared for reefing
