Preservation

Car 1575 has been preserved by the New York Transit Museum and restored. During its service life, it was rebuilt from its original appearance by ACF in 1947 after an accident. It became the prototype for the R10, designed to test new interior and cosmetic features. While it cosmetically resembles an R10, mechanically and electrically it is still an R7A and can only operate with other prewar IND R1-9 cars.
