4590 entered service for the Boston and Maine railroad as  in March of 1935. In October 1958, 4590 was sold to the Long Island railroad, renumbered to their No. 7526 and rebuilt into a typical Long Island commuter car with walkover seats and Black and White tiling, with green tinted plexiglass glazing. In the late 1970's 4590 was retired from commuter service and converted to a Sandite car and renumbered W-85. After it was finished being used in Sandite service in the late 1990s, the car sat in storage for several years. It was finally donated to The Railroad Museum of Long Island on March 3rd, 2008. Since the railroad museum had no use for it, 4590 was donated to the Twin Forks NRHS Chapter. Unfortunately due to lack of resources and funds, the chapter is actively seeking to relocate the coach to a new, and safe home. #4590 is the last Osgood-Bradley "American Flyer" car in existance.
