Hedley Hi-V (New York City Subway car)

The Hedley Hi-V was a New York City Subway car class built from 1910 to 1911, which were motor cars, and then in 1915 an order for trailers that were numbered 4223–4514. All were built by the Standard Steel Car Company, Pressed Steel Car Company, and Pullman Company. These were the first cars built with center doors. They were also the last high voltage cars built for the system because high voltage cars were a hazard to both the train operators and track crews. Thus, all subway cars delivered afterward were low voltage cars.

Service history

These cars ran on both the West Side and Broadway–7th Ave lines and ran with both the Gibbs and Deck Roof Hi-V cars until being replaced by the R17, R21, and R22 cars. The Hi-V Hedleys were retired by 1959 along with what was left of both the Hi-V Gibbs and Hi-V Deck Roofs, which were in very small numbers by that point.[1] Several cars were used in work service until 1960–1961 before getting scrapped. Cars 3712 and 3737 were used as welding cars. 3700–3701 became work motors, while 4267 became a pay car. A fleet of cars numbered 4015–4024 operated on the Times Square shuttle line.[2] The Hedley's standard car body would be incorporated into another fleet of cars known as the Lo-V fleet, which were built from 1915 to 1925. None of the Hedleys were saved, as it was not thought of at the time to preserve for future generations.
