The No. 501 locomotive spent its career pulling the Champion.[1] After retirement from regular service, the unit was restored to purple & silver colors by owner Glenn Monhart. In the 1980s, the engine operated on the Wisconsin Western Railroad, a short-lived heritage railway. It is currently operating at the North Carolina Transportation Museum in Spencer, North Carolina.
