The Deck Roof Hi-V, a New York City Subway car, was built between 1907 and 1908. These cars remained in service from 1907 to 1958 and were also nicknamed the Battleships.
When these cars were delivered, they had two doors on each side until the early 1910s, when they received another door in the middle on each side. Just like the Gibbs cars, the Deck Roofs sent 600 volts into the controller, which was hazardous. Otherwise, however, these cars proved to be reliable throughout their career.
In the 1920s the Hi-V fleet was being converted to multiple unit door control, with the exception of all 50 of the Deck Roofs and some Gibbs and Hedley cars. The Deckroofs were often placed at either end of the train so that ten car trains of Hi-Vs could run.
Until the late 1950s and early 1960s, The IRT platforms could not handle a full ten car train. Thus, the manual door controls of the Deck Roof were reliable, as the side vestibule doors at either end of the train can be opened manually even if the entire car isn't on the platform. However, two conductors were required for ooperation of manual door controlled cars.
When all the platforms on the IRT were eventually lengthened to support ten car trains, the Hi-Vs by then were being phased out by the then new R17, R21, and R22 subway cars. The last of the Hi-Vs were retired in 1959.
Only one Deck Roof car, 3662, was preserved and survives at the Shore Line Trolley Museum. Due to Hurricane Sandy, the car is not operable, and will need to be repaired before it can run again.
