- The futuristic front end of the R40 cars, as delivered, was
designed
by Raymond
Loewy. The slant front end soon proved to be impractical and
dangerous for passengers to pass from car to car. Attempts to improve
the safety of the slanted ends immediately resulted in disastrous
changes to their appearance. Throughout 1968 and the course of the
cars' delivery, the simple handholds were first augmented with larger
protruding handhelds, pantograph gates, and finally, even larger
(higher) handholds. (The metalwork and chains did not age well during
the life of the R40 car, turning the once futuristic cars into ugly
ducklings.) By April 1968 it had already been decided that even such
modifications were not a solution, and the 100 remaining cars on the
order were redesigned. The modified ends were designed by the design
firm of Sundberg-Ferar,
which also designed the MTA "Metropolitan" (M1) cars for the MTA
commuter railroads, and the R44/R46 front ends. The R40 "M" cars
retained their smooth front, blue belt rail paint, and large rollsigns
until circa 1979-1980 when the signs were changed (to the MTA color
bullets) and pantograph gates were installed. "R40M" was not an
official designation, although it is now in common use to distinguish
the R40 cars with the modified (non-slant) end design.

- 4150-4249, 4350-4449 (present numbers 4150-4349) were built under
Contract R40, and 4250-4349, 4450-4549 (present numbers 4350-4549)
under Contract R40A. The fleets were renumbered in 1971 such that all
of the slant-end cars were numbered in order (with the side effect at
the time of also numbering the cars without, and with, air
conditioning in order too).
- Cars rebuilt 1987-1989 by Sumitomo. During the overhaul, air
conditioning was added to the slant-end cars that did not have it
(4150-4249, 4250-4349).
- Mismatched pairs: 4426 & 4429, 4258 & 4261, 4460 (R40M) & 4665 (R42)
- NOTE: Due to the R40 and R40M cars having been renumbered,
the photos indicate the car number when the photo was taken. So
some of the photos will show R40 and R40M cars with the same numbers,
taken before and after the renumbering. Where known, the original
number of the car is indicated in the photo caption.
- Last Run of the R40 Slant-front Cars: 6/12/2009, cars:
N-4425-4424-4415-4414-4398-4399-4257-4256-4433-4432-S, on the "A"
line.
