This RBL-class insulated plug-door 50’ boxcar with Roller Bearing trucks was built in 1967 for Western Maryland. It featured a Hydra-Cushion underframe, roller bearing trucks and load dividers. It was repainted in 1977 at the Elkins Shop into the Chessie scheme. Chessie System was formed through the 1972 mergers of Chesapeake & Ohio, Baltimore & Ohio, and Western Maryland. It remained one of the largest East coast railroads until 1986 when Seaboard System merged with Chessie to form today’s rail giant, CSX Transportation.
