Detroit & Mackinac Railway 481 and 466 pull a U.S. Air Force B-52 Simulator train through Tawas City in 1963.  This was D&M's original paint design after becoming dieselized in 1946.  D&M numbered its diesel engines based on the year they were purchased or rebuilt.  481 was purchased in 1948.  466 in 1946.
