The Western Maryland was assigned 25 ex-C&O GP9s in 1976 after the Chessie merger. These units were never given a full WM paint treatment, but received a half-hearted WM relettering and retained their C&O numbers. When repainted into the Chessie paint scheme they also retained their C&O/WM numbers.
