The Deck Roof cars served mostly in Broadway services, both Express and Local, throughout their lives. A number of trains served both rush hour Lexington Ave. Express services: Jerome Ave. and White Plains Rd., during the period that the regular Steinways were being used in Broadway Express service for a brief period from 1950 to 1952. These were returned to Broadway in 1952 as part of an equipment swap to save on crews. The first 4 of these cars were held aside for the Bowling Green–South Ferry Shuttle and had the center door cutout feature, indicated by the white line outside under the number. 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 the operation of trains with manual door-controlled cars. Unlike the BMT and IND Divisions, full length trains of all older types of IRT cars always used two conductors.
Retirement When all the platforms on the IRT were eventually lengthened to support ten car trains, the High-Vs were being phased out by the then new
R17,
R21, and
R22 subway cars. The last of the High-Vs was retired in 1958. Car 3662 is preserved by the
Shore Line Trolley Museum, modified with trolley poles. It was previously operational, but a flood at the museum site damaged the car's electrical underfloor components. It is currently out of service awaiting restoration. ==References==
