in 2017, after which they were sent into preservation. Currently, another handful of cars are being replaced by reassigned R42 cars. Six cars have been preserved: Cars 9306, 9307, 9308, 9310, and 9343 have been preserved by the New York Transit Museum in Brooklyn. 9306, part of the museum since July 1976, is the only R33S car to not be rebuilt, and thus bears the World's Fair paint scheme and original interior configuration. 9307, 9308, 9310, and 9343 were previously used as work motors based out of Corona Yard, before being retired in 2017. Cars 9307 and 9308 are also painted in the World's Fair scheme, and car 9310 is painted in the "Redbird" scheme; it is unknown what scheme 9343 will be repainted to. All cars except 9343 are fully operational and run periodically on museum-sponsored "Nostalgia Trains", specifically on the Train of Many Colors. Car 9327 is preserved at the Seashore Trolley Museum in Kennebunkport, Maine, painted in the Subway Series livery. The car was temporarily displayed at the New York Transit Museum and was used on a fan trip in May 2005 before being sent to Kennebunkport. It is fully operational, though modified with trolley poles, and makes occasional runs around the museum, often coupled to R22 car 7371.
