Жаңа Йорк метрополитенінің R33S вагондарының тарихы

Retired class of New York City Subway car

The R33S (also known as R33 World's Fair or R33WF) was a New York City Subway car that was built by St. Louis Car Company in 1963 for the IRT A Division. They were purchased for service on the IRT Flushing Line (7 and <7> trains), which was the closest line to the 1964 New York World's Fair. A total of 40 cars were built, arranged as single cars. While in regular service, each R33S was coupled to five two car consists of R36 cars to make 11 car trains for the 7 and <7> routes. The R33S fleet entered service on September 26, 1963, and was originally painted in a light blue turquoise "Bluebird" scheme. The fleet was overhauled in the mid 1980s, during which the cars were painted red, leading to the nickname "Redbirds". The R33S fleet was replaced in the early 2000s with the delivery of the R142 and R142A cars, with the last train of R33S and R36s running on November 3, 2003. After being retired, some R33S cars were preserved, but most were kept for work service; many of the work cars were scrapped in the 2010s.

The R33S cars were numbered 9306–9345. The cars were very similar to the R33 cars, save for differently shaped side windows (three piece curved windows on the R33S cars as opposed to three sectioned rectangular windows on the R33 cars), and the fact that the R33S cars were single cars with a cab at both ends. The cars were built as single cars to make 11 car trains with the R36 cars for the 7, which were built as married pairs. Although the R33S cars were later referred to as Redbirds, the cars were originally painted in a light turquoise blue and white upon delivery. This "Bluebird" paint color scheme was used until the mid 1970s when they were painted in the silver/blue MTA livery. Then, they were painted a full white (roof, bonnets, sides were all painted white) from 1981 to 1982 to combat graffiti; since the white paint was a Teflon based paint, the graffiti did not stick to it very well. The look was abandoned for the famous Redbird style. The Redbirds were painted between 1984 and 1989 to a deep maroon red body, black front bonnets and anti climbers, and a silver roof.

The first R33S cars were placed in service on the train on September 26, 1963. The cars were solely assigned to the (IRT Flushing Line) and were based out of Corona Yard. The cars were rebuilt in house in 1985 by the Coney Island Shop, except for one car (9306), which was not rebuilt and instead sent to the New York Transit Museum in 1976. However, they were not retrofitted with air conditioning system and instead retained their original Axiflow ceiling fans. For this reason, they were not used during the summer months due to poor air circulation or air flow and high humidity; the 7 train used 10 car trains when the cars were not used.
