Redbird trains were the nine train models nicknamed because of their red paint.[1] There were 1,410 New York City Subway cars of the following types on the IRT line: R26, R28, R29, R33, R33S, and R36. All were built by the American Car and Foundry Company and the St. Louis Car Company. They entered service in 1962. Most Redbirds were phased out from 2001 to 2003 and replaced by the new R142 and R142A cars. The final trip made by a train consisting of Redbirds was made on November 3, 2003 on the 7. 1,292 Redbirds have been sunk at sea off the coasts of Delaware (Redbird Reef), Georgia, New Jersey, South Carolina, and Virginia as artificial reefs to promote marine life, to serve as a barrier and to enhance recreational scuba diving by Weeks Marine Inc. Some trains were preserved by the transit museum.
