R8A was a class of New York City Subwayrevenue cars built in 1939 by the St. Louis Car Company, and used to gather and transport tokens from stations along the IND division. 66 and 67 were the only two cars built. Being blind motors, the cars were usually towed around by a set of out of service R1-9 cars. 66 was last operated in 1970, after which it was removed from service, and sent to Jamaica Yard Training Services, to be used as a shed. It was removed some time before 1990, and scrapped. Car 67 was used as a school car, until it was scrapped in April of 1986.
At one point, 66 and 67 were renumbered 20176 and 20177. Then, in the 1970s, they were again renumbered 30176 and 30177.
