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 American Car and Foundry, 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.
