The order contains two forms, a slant version similar to the R40, and a "Modified" version similar to the R42.The R40A is similar to the R40, but R40A was originally delivered with
air conditioning units. As a result of the air conditioning, the standee poles are arranged in diagonal patterns rather than the straight line of the R40. The R40A slant version was the last 100 cars to be built with the end slant (numbers 4350-4449). As of October 2008, the slanted ends run on the NYCS service|B and all 100 of the modified cars run on the NYCS service|A.With the poorly conceived slant design having proven unsuccessful, the
New York City Transit Authority (NYCTA) had the last 100 R40 cars (generally known as the R40M series) built with a non-slant end. The end was redesigned by Sundberg-Ferar, and is identical to the non-slanted end on the R42. The R40M is called a modified or a straight R40 and is part of the R40A car order, consisting of cars numberered "4450-4549". Due to their similarities, the R40Ms and R42s frequently run together. Car 4460 is mated to R42 4665, as the mates of both cars were damaged in the Williamsburg bridge wreck of 1995.In 1988–89 the R40s were rebuilt by
Sumitomo inElmira Heights, New York . The R160 fleet will replace some or all of the R40A fleet. The majority of slant-ended R40As have been retired.External Links
