As theThe all-steel prototype
In 1903, George Gibbs used his influence to contract with the Pennsylvania Railroad's shops in Altoona to build an all-steel prototype for the new subway. This car, numbered 3342, was tested in February 1904 and deemed to be too heavy for practical use in the new subway. It required further design changes before it could become serviceable. But most importantly, the all-steel prototype proved that an all-steel car could be feasible, and validated Gibbs' claims that the previously held fears of excessive vibration, poor insulation, and loud noise were unfounded. IRT engineers began modifying the all-steel design to lighten the cars to a more suitable weight. One of the largest breakthroughs came when engineers learned they could achieve a similar structural strength as the heavier car by constructing a "skeleton" floor frame made of thick, intersecting steel sills and crossmembers. This was in contrast to using a single thick, heavy sheet of steel for a large center sill that supported the car. Following this and other weight-reducing changes, the IRT was ready to go ahead with a production order of the new "Gibbs" cars, named after George Gibbs. Larger builders remained steadfast in their refusal to build all-steel cars. However, as a result of the generally successful introduction of the steel prototype car, the growing American Car & Foundry was willing to accept an order for steel cars. Three hundred were to be constructed, incorporating the latest modifications made by Gibbs and IRT engineers to reduce the weight of the cars. As it turned out, 200 of these cars were initially built, with an additional 100 as a supplementary order. The latter differed slightly from the base order by having aluminum trim on their roofs. As they were being placed in service, many motors from the Composite cars were transferred to these cars. However, to speed the process of placing these cars in service to ready them for the subway's opening, many of the Gibbs cars had newly ordered motors. In 1910–11, center doors were added to these cars, and the facing cross seats in the center, typical of el cars, were removed to accommodate the additional doors. Additionally, the cars were retrofitted with a more advanced type coupler, and the AMRE triple valve braking which was first introduced in the later Hedley High-V motor cars. At this time, 8 of these cars: 3376, 3386, 3447, 3514, 3524, 3567, 3591, and 3638 were set aside for work service and were not modified (see below). 3350 was retired from service in 1930 and became a pay car, stationed at Corona Yard. The sample steel car, 3342, also served as a pay car, converted in 1905.Service history
In 1937, a huge consolidation of the High-V fleet occurred, which set an assignment for these cars. First of all, to facilitate the operation of cars that still had hand-operated door systems with those that had been converted to MUDC operation in combination trains, as such consists were referred to, more cars had to be converted to MUDC. These consisted of 133 Gibbs cars, and the rest of the trailers, the first batch of which had been converted in 1923 along with around 268 Hedley motor cars. Next, the High-V fleet was divided into three groups: for Pelham and Lenox Local service, Broadway service, and shuttle service. Cars in the Broadway Local service were enabled to use the Pelham–Lenox cars for the purpose. The motor cars were equipped with a center door cutout feature and were distinguishable by a white line painted outside under the number. This indicated that these cars were intended to be used in services that operated to South Ferry, City Hall, and shuttle services such as the 42nd St. and Bowling Green–South Ferry Shuttle. Broadway Local trains sharing the Broadway Express service cars that were not equipped with this feature had special trailer cars assigned for the purpose. In 1942, car 3583 was involved in an accident and scrapped. Fortunately, the MUDC equipment from this car was salvaged. The economy-minded Board of Transportation took one of eight work cars set aside from this fleet in its early years, 3514 (the other seven are listed above). The car was converted back to passenger service, equipped with MUDC, and added the white line outside for the assigned service. Gibbs High-Vs were used on the first subway line since 1904 and ran until 1958. They were primarily used in local service on the subway until 1952, when an equipment exchange to save on crews put many of these cars in the IRT Broadway–Seventh Avenue–Van Cortlandt Park 242nd St. Express service as well. 3342 was scrapped in 1956. All other work cars were retired and scrapped by 1960 as surplus Low-V cars entered work service. All hand-operated cars were removed from passenger service in 1957, and MUDC cars in 1958. They were replaced by the R17, R21, andReferences
