W-85 entered service for the Boston and Maine railroad as their 4590 in March of 1935. In October 1958, 4590 was sold to the Long Island, renumbered 7625, and rebuilt into a typical Long Island commuter car with walkover seats and Black and White tiling. In the 1970's it was retired from commuter service and converted to a Sandite car and renumbered W-85. After it was finished being used in Sandite service, it sat in storage. It was finally donated to The Railroad Museum of Long Island on March 3rd, 2008. Since the railroad museum had no use for it, W-85 was donated to Twin Forks. It is currently used for storage.
