Atlantic Coast Line 501

Atlantic Coast Line #501 is a preserved EMC E3 diesel locomotive at the North Carolina Transportation Museum. It was notable for being the sole EMC E3 survivor, though it was rebuilt into an E6 before delivery.
The locomotive spent its career pulling the "Champion". 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.
