Sleep like a kitten in this cozy t-shirt. Incorporated in 1973 Chessie System, Inc. was a holding company that owned the Chesapeake & Ohio Railway (C&O), the Baltimore & Ohio Railroad (B&O), the Western Maryland Railway (WM), and several smaller carriers. In 1972 C&O merged with B&O and WM, with the newly formed company named The Chessie System. They adopted the "Ches-C" logo, which incorporated the silhouette of the kitten into the "C" of the railroad's name. In 1986 The Chessie System merged with other railroads to become the CSX Corporation. Though the Chessie logo is no longer found in advertising and was phased out of usage on trains, there are still examples of rolling stock that feature the kitten logo as they have yet to be repainted.
