The SD80MAC is a 5000 horsepower (3.7 MW) C-C diesel-electric locomotive which commenced production in The SD80MAC also has recessed red marker lights in the nose, an identifying feature unique to Conrail locomotives, although NS has removed the lights on most of their former Conrail engines.

All 30 units built were delivered to Conrail, and the 28 production units were completed, tested, and painted at the former Pennsylvania Railroad shops in Altoona, Pennsylvania. In the Conrail split, Norfolk Southern received 17 units, while CSX got 13. The former Conrail units were the first AC traction locomotives owned by Norfolk Southern, with the railroad waiting until late 2008 to order the General Electric ES44AC. While Norfolk Southern quickly removed the class lights, CSX did not and they can still be seen on the engines.

The SD80MAC is one of the most popular modern locomotives with railfans, partially due to its rarity.
