The R11 was a prototype class of experimental New York City Subway cars built by the Edward G. Budd Manufacturing Company in 1949.

Description

The R11s were numbered 8010-8019.

Because each one cost more than $100,000, the R11s were frequently referred to as the Million Dollar Train. From 1964 to 1965, the ten R11s were overhauled in the Transit Authority's own Coney Island Complex under contract R34. Therefore, it is also acceptable to refer to the cars as R34s, provided one is referring to them in their post-overhaul state.

The R11 was the first stainless steel R-type car (the Budd BMT Zephyr holds the title of being the first stainless steel subway car in the city) ever built. Fifteen years after the building of the R11s, the Budd Company built the first bulk order of stainless steel cars in New York City Subway history, the R32.

The ornamental design of the car body featured standee windows separated by a heavy brace from the lower windows. This was due to the influence of noted industrial designer Otto Kuhler (US patent Des.153,367), and featured as part of a bid by the American Car and Foundry Company in 1947. The cars also implemented new technology in several areas. "Precipitron" lamps were included, designed to combat airborne bacteria. Forced air ventilation was introduced as ceiling vents circulated fresh air in from outside each car, while removing stale air. Electric door motors were used for the first time, replacing the standard compressed air engines which had served on much of the older equipment. However, these cars were also built with outside door operating apparatus or controls along with an exterior mounted Public Address microphone system. Lastly, drum brakes were installed instead of conventional tread brakes.


History

Background

Otto Kuhler's patent of subway car filed 1947 (copied by R11)

On June 19, 1947, the city announced the details of the $1,158,000 R11 subway car order. The equipment in the subway car was installed by Westinghouse Electric.[1]

The full size of the R11 contract was 400 new subway cars, intended to provide service on the planned Second Avenue Subway, which was repeatedly delayed until January 1, 2017. The subway, which was then slated to open in the 1950s, had been repeatedly delayed throughout its history, and the 10 cars ordered were to serve as a newest technology prototype test train available at the time. However, the remainder of the cars were never built due to the halt of construction on Second Avenue shortly thereafter.

Modifications & Overhaul

The R11s originally used storm doors that were similar to those used in later SMEE cars, but by the early 1950s, those storm doors were modified to feature circular windows similar to those on the R15, R16, and R17 cars.[1]

The R11s were rebuilt in 1965 under contract R34. During the rebuild, the drum brakes were replaced with disk brakes, new fans were installed, and the middle stanchions were removed to improve passenger flow. The rebuild also included modifications that allowed the cars to operate in consists with other SMEE (contracts R10 through R42) cars.

Retirement

Despite the rebuild, maintenance for the the cars proved time consuming and difficult by the 1970s, as special skills and components were needed to keep the cars in working order. Because there were only ten R11s, the cars were retired from service in 1977 following a yard accident that wrecked car 8016.

By 1980, nine of the ten cars were scrapped. Only car 8013 survives today at the New York Transit Museum. The car was restored to operating status in 2013-2014 and has been operating on New York City Transit Museum-sponsored excursions since August 2014 - its first public service run in 37 years - specifically on the Train of Many Metals (TOMM).
