EMD SD90MAC

Diesel and Electric Locomotives

The EMD SD90MAC is a 6,000 horsepower C-C diesel-electric locomotive built by General Motors Electro-Motive Division. With the SD80MAC it is one of the largest single-engined locomotives ever produced, and only the dual-engined DDA40X is more powerful among EMD locomotives. It was introduced in 1995 to use the new 16-cylinder H-engine, and features radial steering trucks with AC traction motors and an isolated safety cab mounted on shock absorbers. The 4,300 horsepower SD90/43MAC variant uses a 16-cylinder 710G engine instead. As of 2025 most have been rebuilt as SD90/43MACs, and Norfolk Southern converted 110 into SD70ACU locomotives.
