The Deck Roof Hi-V was built in 1907–08. These cars remained in service from 1907–1958 and were also nicknamed the Battleships. When they were new thy had two doors on each side until the early 1910s when they received another door in the middle on each side. [1] Just like like the Gibbs car this car also sent sent 600 volts into the controller, which was pretty hazardous, but with that exception 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 exception being all 50 of the Deckroofs and some Gibbs and Hedley cars. The Deckroofs were often placed at either end of the train so that ten car trains of Hi-V cars can be run. [2] [3]

The IRT platforms up until the late 1950s and early 1960s could not handle a full ten car train and so the manual door controls of the Deckroof came in handy 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. Though two conductors were required when it came to manual door controlled cars. When all the platforms on the IRT were eventually lengthen to support ten car trains the Hi-Vs by then were being phased out by the then new R17, R21, and R22 subway cars which would completely replace the Hi-V fleet by 1959. Only one Deckroof 3662 was preserved and survives at the Shore Line Trolley Museum and is in running condition, but is not run often.
